Stant 14757 Engine Coolant Thermostat & Water Outlet Assembly Review

Installed on my Civic Si because my old one was leaking, I really only needed the gasket but I replaced the whole thing anyway. Suitable for all still running K20A3 engines.

Perfect for 2002 RSX base. Also contrary to what you may have read on forums and the like, you can replace it without removing the heatsink. If you are careful you can access it under the car.

Although not easy to install on my CR-V, this solved my overheating problem. A small amount of anti-seize paste on the screws will do if/if you need to replace them again. Breaking into the permanent shell that is part of the engine is going to be a lot more of a headache if you're not careful.

Replaced my radiator and figured why not replace the thermostat while I'm there. Put everything back together and the heater stopped working. I had to go back and delete. Screw sticks when removing. There was a headache. As a result, Honda ordered OE quality. Works now. No thank you
