Thread: 2000 GTP overheating and no coolant flow

Are you making sure that the block is full of coolant first, then adding the rad?

Take the thermostat out and fill the block from there, then put it back in and top off the radiator. Put the cap back on and fill the res tank, then start the car and run it till its warm, open the bleeder on the thermostat housing for a few seconds and close it. Do that atleast 5-10 times as its heating up to get rid of all the air in the system.

If that doesnt help anything, you likely do have a real blockage of coolant flow and not just a massive amount of air in the system.

Ffdp bet he is not letting it warm up all the way. I noticed on mine that even tho the temp reads normal the hoses can be cold if you dont let it warm ip all the way. Most of us dont have block heaters like you lol

take the t stat out, put the housing back on, then take the upper hose off the rad. then start the car, coolant should pump out the upper hose, if its not flowing out, theres a real blockage.

you did put the t stat in the right way right? if its upside down it wont work well. maybe the last one one was in wrong too?
