Last fall, the old thermostat in my car started getting lazy. I decided to replace it with a "high performance" 180 degree Mr gasket t'stat. What a piece of junk! When I ran the car last fall I noticed it was running just a touch cooler than the old one. When I got the car out this year, It would barley heat up to 140 deg. I pulled it out and put it in a pot of water with a food thermometer and it started to open at 140. I let it cool down and it stayed open down to 100 deg. A total waste of $16. I'll get a new stant and put back in. Do yourselves a favor and avoid. I should have listened to the many on-line reviews stating that it was junk.
What are some of you guys running for a t'stat? 180 or 195? I like to run the 180. With a 195 I'll get some pinging on a hot day.
