  • The price was great and the installation was a witch
My customer was having issues with her Grand Am running hot, figured we’d start with the hardest things first, and bingo problem solved. The thermostat worked as expected. The price was great and the installation was a witch! But it got done.

  • Works fine
You need a special tool to remove the thermostat housing for a Chevy lumina.

  • Great USA quality bargain
USA made quality, design is superior. For instance, as it starts to open it is designed to initially allow gradual flow upon first opening unlike most other designs that end up dumping a large amount of cold radiator coolant into your engine as they open in cold weather, thermally stressing the block or head. Fit great in GM 3400 application ... show more

  • Actual MOTORAD brand who boiught STANT
Not yet installed. Only can provide any quality review after installed and used for years. Looks like typical car thermostat. It is actually MOTORAD brand, who bought STANT many years ago. Oddly same items appear still sold under both brand names.

  • Good price, works as advertised:
I had to replace the LIM gaskets on the wife's 2000 impala so I though I might as well put in a new thermostat while the engine is apart. Comes with a built in gasket and works as advertised. Just make sure you get the right one for your application! The local auto parts store sold me the wrong one last time, so I had to make a gasket with gray RTV. ... show more
