Thermostat works great, gasket- not so much

Summary: Tested the thermostat before installing and found it operated spot-on the proper temperature. Installed with the supplied gasket and had leakage. Purchased an upgraded gasket and have had no coolant leaks since. Thermostat has been operating fine for a couple of months now and would recommend it.

Yes, I recommend this product.

Would buy again
