Overheating problem
Overheating problem I've recently replaced the thermostat as that was sticking. Everything was running fine up until recently when the Radiator cap on the bottom of the radiator began leaking so I replaced that as well. Now when I start it up and after it gets warmed up the temp slowly begins to rise and won't go back down. The thermostat is brand new so I dont see how it could be that? When I have the radiator cap off from what I can tell coolant is being sucked in and circulating. I know I don't have a blown headgasket. What else could be the problem o what am I missing?

Does the temp rise without stopping and if you let it it will go into the red? if so, your t-stat is not opening, get another one
Just sitting and letting it idle then yes but it takes awhile. 5-10 minutes The temp will go up a few degrees then stop then go up some more, it takes awhile for it to do this but it does and will go into the red.

Does the coolant ever boil over when it gets real hot?
The t-stat could be partially opening up too.
Simple check to see if this is a t-stat issue, take the t-stat out and bolt the housing back up. Start the engine with the radiator cap off and see if the coolant is flowing. It should be. Put the cap back on and go for a drive for about 15 minutes. It shouldn't get hot in 15 minutes of driving.
Then put the t-stat in a pot of boiling water and using a cooking type thermometer gauge see if it opens FULLY when its supposed to.
Checking the temp with an OBDII or other scanner is a good idea, just to make sure you're not chasing something that isn't there. Could just need a new temp sensor.

I'm going to try that with the T stat tomorrow,
I think that it IS actually getting too hot because the fans stay on awhile after I turn the car off, or would a faulty temp sensor cause them to do that as well?
I also plan on checking the water pump tomorrow as well, taht could cause it to overheat as well correct?
Thanks for all the info

I do believe a bad sensor WILL keep your fans on and make them come on and off when not needed. NOT POSITIVE on that, maybe someone else will know.
The water pump will always pump water, they don't stop working, they just start leaking.
