 Subject: T-stat Problems
IP: Logged
Message:
I just replaced my tstat with the Robert shaw and immediately after I ran my truck for about 1/2 mile and it was already hot. I did nothing special but drain through the draining hose and removed tstat and put the new one in. Am I missing something? I put the original stock back in to try and remedy the problem but to no avail. If anyone could please help I would appreciate it. I would like to drive to work monday. Hehehe.

No I checked that when I replaced the new one back to the original stock one. Even read the directions after the first time. Unless they changed the directions for the 4.7. It has me dumbfounded I hope I didn't do anything to mess the truck up. We will see when I take it in on Monday to the dealership. Thanks anyway.

if T stat is in correctly check coolant level sounds like air in system, if that was all you did.

Most likely air in the system. Drain some fluid out ( enough to uncover your radiator core), and run the engine with the radiator cap off. Once the thermostat opens the air should vent out, and you should see a significant drop in fluid level. Then refill your system.

Did not know that. Of course that isn't in the manual. I will try that next time. Thanks.

Does anyone know the part number for the t-stat for the 4.7? The Robert Shaw GT755-180 isn't listed for the 4.7. Does it still work or is there a different one for it?
Thanks

I was told that one is correct. I have seen a couple of other post where they have used these and had no issues. The strange thing is I saw no gasket on mine. Did not put one on and still had no leaks. It had a plastic ring that housed the t-stat. I guess that is what formed the seal. I will attempt the 180 tstat again this weekend knowing about the plug that needs to be pulled to keep the air pockets out. Thanks for all of your help.
