I just finished up the lim job on my 02 GTP and it's immediately overheating as soon as it starts. I've opened the bleed screw on top of the thermostat and I've filled the radiator up. But still as soon as I start the car the temp gauge climbs up to max so I shut it down. Can anyone point me in the right direction?

*meep meep* calling ScottyDoggs.

Was your temp gauge working fine before the LIM job? The temp guages are known to be faulty. But try removing the thermostat and see if it overheats still.

take the t stat out, fill the t stat hole with coolant if none is seen.
when you open the bleeder whats coming out? coolant air or bubbles?
09-14-2015
Did you open the bleeder while running or when it was off? If it's registering hot when you first start it after sitting I would guess the sensor is bad.

Temp gauge was working fine previously however the plastic clip got broke at disassembly so I replaced it with a bwc one.
I started to the process with the car cold and opened the bleed valve from the get go. Nothing at all is coming out of the bleeder, but it doesnt help I can't run it for more than 20 seconds before it overheats. I did install a stant super stat 195 while doing the lim job.

take the t stat out, make sure its in the right way, then fill the engine via the hole in the lim.

If your car was stone cold when you started it, it shouldn't overheat in 20 seconds, especially if you put at least some coolant in. Have you checked to see if the coolant you put in was leaking? Maybe your LIM gasket was off centered when you re-installe everything and coolant is draining into the oil pan? Just a thought.

Removed the thermostat and the lim is full.

leave the thermostat out. take the radiator cap off and close the bleeder for a few minutes. sometimes it helps to jack the front end up. moves the air to the top of the engine.

you did put the belt back on right? if the belts on do you see any movement of the coolant in the rad.
09-14-2015
Yeah, the belt is on and yeah adding Coolant to the radiator it sucks some down and I kept adding more until it stopped going down.
09-14-2015
run it with no t stat. see if the temp goes up fast, if it does your sensor is messed up maybe, or the wires to it. you did plug it back in right?
09-14-2015
he did say he swapped sensors...could be a DOA sensor or he screwed up the wires/plug when removing it.
09-14-2015
swapped the sensor? put the old one back in.
when i did my engine swap i reused my 233,000 mile old temp sensor vs a new one for a reason lol new suck.
09-14-2015
he said he broke the old one removing it..

so put the old one back in and tape the plug on the sensor?
09-14-2015
The old one was thrown away. Just removed the new one and got a replacement, same results on this one too...
Any other good ideas? Removing the thermostat and running it without one it did the same thing.

Then your car is not actually overheating, the temp gauge is just saying it looks like it is. SgtMarshal said his temp gauge will reach 260* before the thermostat opens, so his gauge is way off. I'd hook up a scan tool to see what the actual temperature is.Originally Posted by Brammer

could you actually see the coolant circulating ?
