how can i fix a 1985 dodge camper that overheats?

Question

i checked the thermostat and thats not the problem.. it will drive for a while then overheat

Answer 1

It's almost certain to have a clogged radiator at that age. Only an idiot would suggest removing it to clean it. That would cost just about as much as putting in a new radiator. Trying to clean the scale and junk out of an old radiator is just going to get you a corroded radiator that will quit altogether soon and possibly toast the engine. If it's a camper, it would be a good chance to get a better radiator than the stock one.

Answer 2

The thermostat is never the problem (well--rarely the problem) as you have found out. NEVER replace any part till you know the problem. Don't waste time and money with flushing, it won't work. Remove your radiator, pretty simple, and take it to a RADIATOR SHOP to be cleaned. I got a '84 Dodge, two pass radiator, cause I live in the Mojave desert, gotta keep it cool, cost me $60, problem solved

Answer 3

I would;d double check the thermostat. Then consider flushing the cooling system. Then check timing.

Answer 4

I WOULD SAY THAT FOR THAT AGE OF VEHICLE THE RADIATOR IS PRETTY CLOGGED UP BY NOW.

HAVE IT CLEANED, BOILED AND RODED OUT COMPLETELY BUT BEFORE YOU DO THAT HAVE THE RADIATOR SHOP DO A FLOW CHECK ON IT AS WELL.
