This maybe a dumb question but Im learning from yall!

My car over heat last night quickly in traffic. I pulled over at the nearest mall to let it rest.
thought it would be fine......and headed back home.
but It went back towards high! I assumed it was the
thermostat, so I drove and made it to the nearest
autozone. Convinced me to get the Fail safe one. Knowing I had to go to work early...I got my flashlight and attempted to install the thermostat. I gasket didnt feel right but installed it anyways. This morning on the way to work, the temp went back towards high.
Got to work , opened the hood to check it out.I had tightened the bolts pretty good. But, noticed coolant leak at the gasket area.

So, dumb question, would that still cause the overheating?? I saved the old gasket, looks fine , may reuse it.

Thanks

Better to start your own thread to avoid responses to the original questions that ignore yours.

Regardless...
No, the new thermostat, even if leaking, would not cause your car to overheat as long as it is opening when up to temp. New parts are sometimes bad, but it isn't likely. You need to use google to search the forum (search "geometroforum overheat" or something like that and do some reading to determine what the possible causes are and how to check them. Could be a bad water pump, blown head gasket, clogged radiator, or a few other items.

first thing fix that leak and even if the thermostat was the problem it could still get hot because of air in the system from changing out the thermostat-when ever I drain coolant for any reason it usually takes 3 or 4 times of filling radiator to top, replacing the cap and running the engine a little, letting it cool a little if i took a short drive and removing the cap and filling it again-if you're so inclined you can test your old thermostat by heating it up on the stove in a pan of water-as it gets hotter in should open-the using an egg grabber put it in cool water and see if it closes-and it could also be any of the things MMM mentioned-

Every thermostat i buy that dont have the "jiggle valve" i like to put on my drill press and make a small hole in a similar location to help bleed out air. I have had a couple brand new bad out of the box thermostats.
