Heater hoses

[naa10104]

Hello, want to replace the heater hoses in my 73 non-air-conditioning car. I get the basics but I want to know if there's a correct sequence to do this t[/align]o minimize spillage and avoid an air pocket in the cooling system? Appreciate any comments. Thanks Steve [align=right]

Hi Steve,

normally it is an easy fix. Drain the coolant out of the radiator in a clean jar - you can reuse it later. Change the hoses old against new. Clean the joints if necessary. Fill off the coolant. Then let the car run until it gets warm and set the heater on warm with ventilation for a while. To do so all possible bubbles would have gone.

Principally the same procedure as on every car.

Hope this helps ::thumb::

TIP:

Slice the old hose along its length at the nipples and

peel it off instead of just trying to twist it loose.

Run the engine after filling with the cap off. It should burp out most of the air within 20 minutes. Anything that may be left after that will work itself out on your next couple drives.

I did this recently and also found a hose lubricant that Autozone sells. this lubricates the hose and fitting when putting it back on as well as preventing the rubber from deteriorating.

I know when I took mine off, I'm glad I cut the hose since it was really stuck to the fitting and would have never twisted off. Other posts on here mention using too much force trying to pull the hose off and breaking off the fitting.

I have always used anti seize on the inside of the hose and on the nipple at the connections to prevent sticking. The rib on the nipple keeps the hose from blowing off and usually only 16 lbs. of pressure in the system so not much. Don't over tighten the clamps it will cause the hose to fail early.

Hope you don't have to change the heater core that is a job for sure but you don't have air so it is easier.

Thanks all ... great advice ! By chance anyone know the correct ID and OD of the correct heater hose for 73 351 C ?

Hi Steve,

you have to buy these - I bought them for my 351C 4V without A/C and they seem to be correct. My father has a completely original 351C 4V vert and you can even see the original script like the reproductions.

I bought it there

That has to be the correct numbers and color on it...
