Well this problem has been happening for a month now. I replaced my motor about two months ago. Now the car doesn't overheat at all, actually temps are perfect. Now after driving for a long period of time, I will park the car and you can hear the thermostat "belching" for lack of better words. The upper radiator hose and radiator is boiling hot as compared to the lower hose is normal. My coolant temp sensor was changed because the previous broke. Problem is, i have a 90T auto harness and the only sensor that properly connected to the harness was a 86 n/a(obviously) sensor. I'm not sure if this is the root of my problem but I just mentioned it just in case. My boy "queenskid926" told me that there's air in the system and to burp the car. Guess I was just looking for more incite.
Wierd coolant problem

gauge temp sensor is common to all the years.
efi and cold start sensors are not.
If your top rad hose is hot, and the bottom is cool, your radiator is doing its job...

^Either that or its blocked and hardly circulating at all. Take a temp gun to your upper hose and lower hose and find out what the real temperature is. If it is in fact boiling youre either too hot, dont have the proper coolant mixture or your system isnt holding pressure. The stock gauge isnt a very good indication of temperature btw its just a ballpark reading
i figured it was a pressure related thing but the thermostat is good and so is the cap. don't know what else is pressure related when it comes to the coolant system
thats what i was recommended to do. was just looking for a lil more incite but i guess i'll try it.
"burping" these can be a tad tricky. struggled with mine a tad bit. there is a sticky on here that has very good insight on how to do it effectivly. i havent had any trouble since i did it.
best thing to do, get the front up in the air, with it at opperating temp, and as long as your SURE your rad is not bogus, and you have NO leaks, let it idle for a little while with cap off and heater all the way on, then what i did was rev the motor slightly from under the hood, maybe bout 2k, hold it for a few seconds, then slowly let it come back down. this keeps it from shooting back out at ya, did that a few times over the course of 30 or 45 min. never had a problem since.

yeah theres a leak at the thermostat housing. when parked and started the next day, the belts will squeal because of the coolant that fell on them.
