So, in summary, the right thing to do is run a Cleveland specific thermostat and there are no issues?

The block off device is needed if you divert from the stock setup?

I've had no obvious problems with my 351C running a 180 stat and although my parts store gave me a stat listed as for the Cleveland, to be honest, I had no idea that there was the requirement to block off the restrictor hole. This is news to me. As many will know, my engine is currently being rebuilt, so I will now ensure that the correct Cleveland specific thermostat is used..... if I can find one in Canada. To me, this seems to be counter to logical thinking, but what do I know!!

Thanks for bringing this thread to our attention.

Geoff.
you only need to block the restrictor hole if you use a windsor stye t stat instead of a cleveland style one . i just fixed a car that would creep up in temp a little bit in traffic ad it had a windsor t stat with the factory bypass plate s i pt the factory cleveland t stat in it and it cured the problem . there are a lot of variables that affect water temp . i have been fixing overheating probs fo 40 years so i have pretty much seen it all and some of it wasn't very pretty.

Thanks Barnett468, Now I know what to do.......... buy the right stat!!

As you know, my engine is as stock as I could make it, so as long as I install a stat that was MEANT to be in it, everything should be hunky-dory.

Glad you liked my engineer joke. However it should have read; ...tell HIM much, not them, but what the heck eh!

no, there have been thousands of issues with stock factory ford parts.

Yes but a high flow t stat should also be used.

Here's two charts that info came from:

ok, unfortunately the block off plate will not compensate for an inadequate cooling system . . if anyone wants to know how to keep their car from overheating when its over 100 degrees, feel free to let me know...also be prepared to spend some cash because you will be buying some parts.

one of the things to do to reduce engine temp is to tune your distributor to your particular engine . . if your timing is too low for your engine, it will be more difficult to make it run cool.

.
True Barnett. Block off plate or brass bypass washer, which ever way you decide to go "...will not compensate for an inadequate cooling system." When that person then has an overheating issue, they will blame it on the plate -vs- washer decision when, in truth, it is more likely radiator, water pump, timing, fan shroud sealing...etc.

Yes but a high flow t stat should also be used.

...or buy/use the parts mentioned above (from the machinist on Ebay) since they are not the "stock factory ford parts..." They are better quality. They will not CURE your cooling problems, (I never stated/implied they would) they will just work better (potentially) at sealing the bypass (skirt of the bypass sealing off the hole/orifice in the brass bypass washer) when the thermostat is in the open position.

Barnett468's statement "...the original system also works fine when the parts mentioned above (the parts on Ebay, I'm assuming, since this quote was a reply under my links of the parts on Ebay) are used . the factory parts didn't work well . the prob is not the concept, it is the crappy parts ford used to build the system with."

The thermostat I listed the link to, sold by the machinist on Ebay, is the original Robertson High Flow thermostat. I'm pretty sure you can't get this High Flow thermostat with the copper skirt attached any longer. It is not made. Similar "skirted" NON-High Flow stats can be acquired from Amazon and Napa. They MAY/COULD introduce an additional variable, since they are only similar. I have suggested and I personally use, the parts sold by the Ebay machinist in an attempt to use the "concept"^ but improve upon the "crappy parts ford used."^



the design is to allow the heads to warm up evenly . this is to prevent them from cracking due to the thin walls in the water jackets.

the block off plate has cured many pantera hot running probs in spite of the poor design of the rest of the cooling system.

the brass colored thermostat you have also looks like a high flow one and just using a high flow thermostat has helped reduce temps in many cases so its not possible to contribute a hot running cure to the machined brass parts alone.
Yes, it is the high flow Robertshaw thermostat that the Ebay seller (the machinist) adds his machined skirt to. This high flow design with the skirt is how the Cleveland's cooling system was originally equipped. The others, although they are quite cheaper, are not as refined and it was important to me to have the skirt, of the thermostat, flawlessly mesh with the orifice in the brass bypass washer. When you want something to mesh flawlessly, you go to a machinist AND pay him to do it right.(he's already done it) ***THESE PARTS WILL NOT "CURE"^ HOT RUNNING PROBLEMS IN ALL CLEVELANDS. :shootself: THEY MAY WORK BETTER THAN CRAPPY PARTS THAT MAY NOT MESH TOGETHER WELL***

Personally, I have done everything I could in planning and building my engine to assure no overheating. In fact, last summer I was in 2 cruise nights, 95°+ temps on the road, sitting in traffic (parade of hot rods), with my windows up, Classic Auto Air blasting (it was literally cold), for over 2 hours and my temp never rose above 180°. 3 core brass radiator and dual Spal fans with a Painless controller. I too, was amazed.

http://www.amazon.com/Spal-30102130-Dual-Extreme-Performance/dp/B003PB9S8G?ie=UTF8&psc=1&redirect=true&ref_=oh_aui_detailpage_o06_s00

Well worth it.

So, maintaining bypass is part of a system (that needs to be understood) and may not "cure" an overheating problem but you start by doing all the little things right and you'll end up with a more dependable machine. ***Yes, an electric fan can malfunction...but so can a fan belt or a water pump belt. :shootself: ***

This "brass bypass washer" subject has mucho content on this site written about it. There are strong opinions. People like to defend their point of view. All I'm saying is you'll have a better chance of it working as the engineers intended to, if your parts work together nicely. Get good parts. Pay the $125 for the good washer and thermostat and know you made the best choice for your beloved engine...a small price to pay.

If any of you want the Aluminum Pantera blocker plate, I have a brand new one, in the box, from WCCC (who did not invent/make it-they only sell it AND none of the WCCC guys use it in their Clevelands), that I won't be using.

Our purpose here is to help others gleen information and make decisions as to how to proceed in their builds. My only intent, is to help, as many here have helped me. Read everything you can and never just listen to one person's opinion. Discern the truth from all the information you gather and proceed how you see fit. (to me that's where the fun is, you get to chose for yourself) Good luck on your builds, keep the passion and do it right or don't waste your time.

By the way, respectfully, your last sentence would make more sense with the word "attribute" as opposed to the word "contribute."

or buy the cheap ones at Napa and Amazon, they are similar but not High Flow and the skirt that seals the opening in the stock ford bypass washer is not constructed as well. You will save $50-60 with one of these, that's up to you, obviously. Good luck with it!

installing electric fans does not make a system more reliable since they can fail . also, since good electric fans flow more air at low speed than a stock fan does, they will cool the engine better at low speeds, so again, you can NOT attribute improved cooling or efficient cooling to the custom made parts as it seems like you are trying to do.

Also, i don't know what you mean by saying that none of the west coast cougar guys use the aftermarket bypass, because this is wrong . i was in the west coast cougar club and i used it and i know several other people that used it.

there are many things the engineers designed on the cars that are less than ideal for one reason or another, so not everything they did was great just because they were engineers . if everything they did was great, no one would have had problems with the original bypass design working properly because ford would have machined the parts for it instead of stamping them etc.

no one would be lowering the upper control arm pivot point to drastically improve steering with ZERO adverse effects.

not every single 289 mustang would have overheated if you drove it with the ac on in 110 degree weather.

the auto trannys would have always fully engaged the parking pawl when they were put in park instead of sometimes coming out of park allowing the car to roll freely down hills until something stopped it which was often another car or a building.

the pinto would not have ever exploded when it was rear ended.

the rear door latch on one late model vehicle would not have randomly opened dumping any kids that might have been leaning against it, onto the road.

the list of factory flaws is virtually endless.

these cars came with bias ply tires but i dont know a single person that uses them other than a concours guy.

Electric fans use electricity, yes. Stock fans use belts. Both can break. My electric fans will more reliably cool my engine than my stock fan would, in a wider array of situations than my stock fan did.




Also, i don't know what you mean by saying that none of the west coast cougar guys use the aftermarket bypass, because this is wrong . i was in the west coast cougar club and i used it and i know several other people that used it.

I was speaking of the owner of West Coast Classic Cougar, Inc. WCCC (http://www.westcoastclassiccougarinc.com/index.php) and his staff. The owner told me that "they sell it, they don't know much about it and do not personally use it." Just because they sell it, is not an endorsement of it. They did not invent it, do not manufacture it, do not use it but they will take your money if you want it.


I don't know anything about your "west coast cougar club."





Any other misunderstandings you need cleared up?

yes, i was referring to the ebay link posted by EBSTANG . These are the best and safest option if you use the stock style system . the problem is that there is no way to tell for sure if te stock system is working and sealing properly because you can not see inside the engine, therefore, if you have a hot running condition and the stock system, the stock system is suspect . if you replace the stock system with the bypass plate, it totally eliminates the possibility of the stock system being the problem, and since blocking off the bypass can be done with a fifty cent freeze plug and some JB QUICK, it is FAR cheaper to try that avenue first than it is to simply throw a new $400.00 radiator at it, especially if your current rad looks clean inside and ypur fans are working.

if it still runs hot then look at the other fr more expensive areas and once t is fixed, you can simply wire wheel th JBWELD off ad revert back to the stock system and if your tems remain the same, you are good to go . if thy increase, your stock system is obviously failing as well.

if you modify your engine for higher hp and bore it out, it's cooling requirements will be greater, therefore, a bigger rad is needed . the demsr the rad core is, the more ifficult it is for air to flow thru, therefore, a better fan is usually necessary also wjen installing a bigger ad.

if the engine runs hot in traffic but not on the open road, you need better fan . if it runs hot on the open road, you need a bigger rad.

a bigger rad works better with a high flow t stat and high flow pump or faster spinning stock pump which ca be achieved wit the use of a smaller water pump pulley.

all chinese made rads have tubes that are at least 25% smaller than us made tubes so this must be taken into account when buying a rad.

do not assume that an electric fan will flow more air than a stock type fan, and in fact, very few do . the best fans are the big spall and factory taurus and lincoln fans . these will in fact suck small children and animals right off the sidewalk and increase your mileage by 2 mpg as they pull your car along.

a fan controller should e used with these because they should not run on high all the time DCC controls makes two very god and very popular ones.

if your engine rums hot, it can also be due to incorrect timing, incorrect plugs and incorrect jetting . this items should be looked at as well if you have a hot running condition.

probably 99% of engines in the older cars have less than optimal timing even if it is factory timing on a factory car because starting in the 70's, the factories had to start using timing specs that would allow the cars to pass emissions inspection.

OK, OK - the dead equine is sufficiently tenderized. Geez.

Look guys, as the actual originator of this thread, the point was to ask if the WCCC block-off plate could be used as a replacement for the unobtanium factory Cleveland restrictor bypass plate with some modification, which segued into the discussion on the merits/shortfalls of the Pantera Mod. The added discussion of having a properly working cooling system vs. a poorly operating cooling system along with the sharing of the correct Cleveland-specific thermostat applications is valid and added value to the information provided.

I asked because I kept getting Windsor thermostats from the local parts stores due to not having the right P/Ns, since the kids at said parts stores don't know anything more that what their computers tell them. Since I have employed the Pantera Mod, my engine's cooling system is working wonderfully - as it should, since everything is brand new (and unrestricted by old or failing components).

The bumping uglies of egos and subtle sniping as a result, however, is unwelcome. Let's stay on-topic, please.

I agree with everything you just stated in this post, my friend. I just chose to start with (when building my 408 Cleveland ) the pricey thermostat and a new brass bypass washer since "neonfiddler" (Ebay guy) did such a nice job perfecting them. This does not mean these parts will perfect a cooling system, just that he did a great job perfecting the parts! I truly appreciate a finely made part, especially one made by a small business in the United States! :sbalute:

You obviously did a lot of research and some testing when you looked into this which is great, and your comment about the high quality made parts for the stock system and link to them are both great as very few people know of these parts and where to get them.

As I am guessing you realized, my entire point was simply with the crappy parts that don't always work as intended and not being able to visually see if they are working.

Also, if i remember correctly, the orig t stat on a Clevo was a high flow like the one you bought from him, and if that is the case, even if the standard flow t stats did seal properly, an engine can still run hotter than it normally would solely because the t stat does not flow enough.

This system is a good example of a good idea that was poorly executed.

PS - Yes, attribute is a more accurate word than contribute . I was tired when I posted that . That's my excuse and I'm stickin to it.

Semantics. When on a forum, especially when contributing the written word to a forum, (or any other "text only" communication) semantics is key. Texts/emails can lose much in translation. People, in general, (not you specifically- everybody) need to take the time to text/email exactly what they mean and not speak loosely and leave the door open for miscommunication. (Very important in today's wold of non-face to face correspondence). There are many people who like to give their 2 cents but won't invest their time in others enough to write a concise comment. (or novel, as some would call it)

Thank you for your well though out comments toward the end of the thread Barnett.

Go to this Ebay site. I have no affiliation with this man, other than I purchased the brass washer, a 180° & 195° thermostat from him. Now listen......I testify with my reputation on the line, that these are quality, better than new. The brass washer is a higher quality, more finely machined piece, period. The skirt, is machined and pressed onto the correct robertshaw thermostat. This skirt is thicker than stock material and is much higher quality than the others available on Amazon and at Napa, I know because I have the Amazon ones and the Napa ones on my shelf in my shop. I spent big bucks on my engine and I obsessed over this issue a year ago. I bought all of them and tested them.

This guy on Ebay is a machinist and a Pantera enthusiast but he does not believe in the aluminum blocking plate. Either do I. (I also have one of these plates and contemplated using it) Get this next concept clear in your mind: It is not a restrictor plate, it is a bypass washer. A restrictor plate is something altogether different. My Cleveland, with 425 HP runs perfectly using these parts, I currently use the 180°. Again, I have no reason to recommend this guy other than when you have the parts in your hand and you compare them to others, his are of better quality.

His washer and thermostat will cost you $100 (last year), now they are around $120. I know it sounds like a rip off but what do you think he should sell them for...his machinist time is worth it for my engine. If it is not worth his time to make them, why would he? He doesn't make runs of millions of these, each one is machined. Go to his site and read. Educate yourself. Don't cheap out.

Good info ebstang, just re-read the entire post from beginning to end and actually learned a few things. That is difficult to do as I get older, but it does happen...

I would also like to apologize to 4x4 for taking over his original post, I was just looking for thermostat information for our rebuild. Clevelands are quite interesting engines in this regard.

:thankyouyellow:

 
No worries, Mystic Fish - your questions and comments are relevant to the thread... and you're right: Cleveland engines are somewhat of a different breed it seems. :cool:

 
.

yes, the problem is not the concept of the cleveland system . . the problem is the design and parts used . . this system did not seal all the time when it was new which is why guys were changing it on new cars . . there are some cars that have the clevo system and theirs work just fine, but if you get rid of it, you 100% eliminate it as a potential cause of overheating.

the problem is that you can not actually see the system in operation so there is really no way to tell if it is sealing or not . . if you install the block off plate, it will seal.

if you have an aftermarket water pump that does not have the bypass, you should drill the bypass hole in it if you use the block off plate.

also, you can drill three 1/8" holes in the perimeter of your thermostat if you use the plate.
If you want to use the factory brass bypass washer & the correct skirted thermostat, you need to use an original factory water pump, an edelbrock water pump or a FlowKooler water pump. They all have the bypass bored into them to mate up to the block where the bypass connects. If your pump does not have a bypass bore in it, it does not matter whether you use a brass bypass washer or a block off plate. You could put nothing in that location because it would lead to nowhere.

My Cleveland had a Weiand pump on it when I bought the car. The weiand pump has no bypass bore. If anyone is interested I have pics of that pump and the pics of the bore process to drill out the bypass passageway to use that pump. This FlowKooler is what I chose after researching all available. It seems to be working great.
