Problem with truck overheating
About two months ago I hit a cow. It pushed the radiator back into the fan, cracking the back of the radiator. When the body shop fixed my truck, they replaced the radiator and fluid. Also the thermostat had to be replaced, it had stuck closed. Before that, the temp gauge, when the engine was fully warmed up, would stay almost exactly at the midway point. For the first few weeks after I had it fixed it was reading the same. But it's the middle of winter, and the temperature had been in the 40's and 50's. Last week it got into the 70's. I noticed that when full warmed up the needle would be just above the midway point. But when I got out, then got back in and restarted the engine, the needle would be 3/4ths of the way to the top of the gauge. When I would start driving again, the needle would go back down to the middle point of the gauge. I thought that the fan might not be working. But I checked it while the engine was running, and it was turning. So what could be the problem? I think that the body shop may not have mixed in enough water with the anti-freeze. But I'm not sure. Thanks for any help or ideas.

RE: Problem with truck overheating
i'm sure your more familiar with how your temp gageacts, than I am,but, I don't see any concern. I believe the water temp will go up a little on any vehicle, when it is first killed.
You might talk to the shop that did the work, see what they have to say.

Moe in Wichita,KS. I read a story about one time when Chrysler changed the co. that made stats for them. the new co. was used to making very close tol. valves, and the stats they made for Chrysler were air tight. to get a cooling system to fill easly Chrysler engeners said to drill a 1/8 inch hole around the outer edge. i have done this for decades, with no trouble.
to seal the stat use permatex #2 put a small amount in the grove in the housing. and some on the other side side of the stat then put the gasket on. but not the side of the gasket that goes to the manafold. this keeps the sealant where its easer to clean the next time you take it apart.

bleed the system.. classic symptom of air in your cooling system.. listen close when you take off. do you hear water running thru the system? sounds like water running thru pipes.. to bleed it.. park the truck with the front end higher than the other .. (i parked mine with the rear end of it in my ditch.. you can also park the front end on a curb .. make sure the system has no pressure.. and take off the radiator cap.. put in some 50/50 to full.. start the truck.. if you see bubbles while its running.. theres air.. leave it running and fill as needed till its full.. stays full.. with no bubbles.. might take a while.. but thats what it sounds like to me
