hey guys i replaced my thermostat, and its still overheating like a bitch. could it be a clogged radiator? it seems it only overheats on longer trips id say above 20 miles. but then again it only overheats randomly. i replaced my thermostat and coolant, could it be anything else like a clogged radiator? its been sitting for 6 years like i said before. any help is appreciated.

May be the heater core

Well really its just an educated(sort of) guess. I dont really know why it would be but i had a '92 taurus that acted up like that and someone had mentioned it could be the heater core so i just bypassed it. Never had that problem again. But as you said it could be a clogged radiator. An easy way to check is to pull the top and bottom main hoses ( they are like inch and a half or 2 inch) from the water inlets in the engine ( dont remove them from the radiator) take a waterhose and run water through the top radiator hose and let it come out the bottom - you will know if it is clogged and it will half ass flush it too.

Then again sometimes parts from the autostore come faulty, try another thermostat

also today i just opened up my radiator, it was very low, bu then again i just replaced the coolant and all that, could it have "burped" out the air and all that space needs to be filled up again?

Possibly. What I usually do when I replace my coolant is fill it, then let it run with the cap off and if it goes down I fill it while its running to help get rid of the air pockets. I'm sure theres a more proper way but this works for me.

well when i do that, it spits all the antifreeze out of the top of the radiator, well more like pours it back out, could there be a hell of a lot of air in there?

took it for a test run, does something interesting, it seems to cool down when the rpms go up

rpm or speed?

rpm i believe, but when it sits and idles it gains a lot of heat, but when i start moving it cools off and when i turn the car off i hear it bubbling in the reservoir

check to see if any water is coming out of the wheeping hole in the waterpump. It could be a blown head gasket, or radiator as well. I would bypass the waterpump all together just to make sure its out of the equation. If you have a clutch fan, stick a bolt in it. If the clutch is screwed then the fan could not be working as well.
