I have used Peak antifreeze since the first time I changed it out in the vehicle about 2 years after I bought the truck and I used it again this time. I am assuming it is compatible since I"ve never had a problem with it before. Had a similar heating problem in a Suburban in the past and discovered the problem then with current. Replacing it with Dexcool fixed the problem in that vehicle.
I flushed the entire system about 2 years ago (probably had done it a couple of times before also). Also replaced the radiator at that time, along with water pump.
Never have checked the current in this system. Would that keep other components in this system from working properly? Do you mean grounding straps attached to radiator, other metal parts of the cooling system, etc?
Someone else mentioned that this vehicle might have some kind of flow restricting device in the cooling system and if it is not present it could cause this problem, but I can't find anything about that in the actual Ford repair manual (two volumes) that I have for this truck. Do you know of any such device in this system?
Thanks for your reply. The help/suggestions are greatly appreciated.
