Your cart is empty. An engine's thermostat regulates the temperature of the engine by controlling coolant flow, its job is to block the flow of coolant to the radiator until the engine has warmed up.
Symptoms of a bad or failing thermostat: high temperature reading and engine overheating; low temperature reading and underheated engine; temperature changing erratically; coolant leaks around thermostat housing or under vehicle.
NOTE: If the thermostat has a jiggle pin, check valve, or other feature to assist in bleeding air from the system in a vertical installation, the jiggle pin should be located at the north or 12 o'clock location.

Gasket slightly undersized on width. Not the same as original. Bought another gasket on Amazon and it was good. This thermostat also causes my temperature gage to move slightly hotter than the original, and it was not as beefy as original. However, it is installed on my ol' RX330 and it works.

Fits. Includes rubber gasket for thermostat. It has the necessary air bleeding hole. Temp stamped on product is 82 C which is also 180 FI bought this version because I believe it is better than the OEM version.Advice for Solara repair:-My old thermostat was stuck open causing the temp colder than expected engine trouble code-The thermostat on this V6 engine is in the top of engine drivers side beneath the air intake and lots of wires/tubes. More difficult than the 4 cylinder.-There is an O-ring in the connecting coolant pipe that you may want to replace or have on hand. This is not included with this thermostat. I used the old one, no leaks.-Engine thermometer is plugged into the Solara thermostat housing... you may as well get a new one in case of breaking the old one off. It’s a tight space maneuvering the thermostat housing around tubes and wires with the thermometer still on, but it is possible. I did it. You can too.

The main issue is the gasket that came with thermostat was too thin and the housing could not get a good seat. What you get in return is coolant leakage. In my case I thought the bolts holding the housing were not tight enough so they were tightened and one of the housing studs broke off. Fortunately there was enough left that I could back it out of the block or we would of had to try to tap out in a very small work area. Went to Toyota dealership and bought studs, nuts and thermostat and gasket. When comparing side by side you can visually see the difference in gasket size. So after a week of leaking coolant and several gallons of antifreeze my advice is to buy OEM thermostats for your Corolla.

The thermostat seems to work great. The gasket that came with it is really thin, much thinner and harder than the Toyota thermostat that was in the car. I replaced the gasket with an AC Delco gasket that was closer to OEM. No leaks yet🤞
