I have a 73 grande and i want to remove the heater box. But i don't know how to. So can you guys point me to a website, video or just tell me how to remove it
OUCH...hate when that happens.
I can provide service manual instructions, which are actually pretty good as I recall.
I also believe there are foam seals which you will find to be trashed. In addition to the heater core, you should try to get a kit to replace the foam seals as well.
Because it is summer, if you do not need your heater, but need your car, you can remove the heater hoses at the engine bay fire wall and hook them together. You will lose a little heat dissipation, but other than that you should be fine.
GOOD TRUE Heater hose is hard to come by. I will see if I can help in that regard as well.
And LASTLY, you may want to replace your thermostat. There is a VERY IMPORTANT THREAD regarding the BYPASS VALVE for the thermostat that you need to read and understand.
And LASTLY LASTLY, there is also an important thread regarding the radiator cap. If you have an overflow tank, you need one type of cap. If you do not have overflow, you would use a second type.
Good luck...piece of crap radiator core.
And, if you don't want to do it, there is a thread running here about how great these Mustang wives are. Perhaps you could ask one of them replace it for you.
