Customers say
Customers find the thermostat works well, with one mentioning it saved their engine, and they appreciate its quality, with one noting it performs better than store-bought alternatives.

The thermostat has a perfect fit, but customers note it lacks a gasket.

Works great.
I had another thermostat in my car (Not an cheap knock off company either) and my car always ran hot. Tested both in a pot of hot water and this one opened when it shoud. My car rund much cooler now. I could not be happier. From now on this is the only thermostat I will run in my classic car.

Works great but I needed a rubber gasket
The thermostat is good quality and accurate. I installed this in my 1994 GMC that the previous owner had removed. This didnât fit the housing, it was too small. I went to the local parts store, where we found a gasket that goes onto the thermostat. Itâs like a grooved rubber o-ring. Once the print was on, everything fit and went back together as it should.

Good quality!
Wish it was US-made but oh well. Seems good quality nonetheless. This size (54mm) is universal for most older GMs and some other makes too. Obviously it does not come with a gasket because a Chevy thermostat housing is different than an Olds housing, which is different than a Pontiac.

Fit my ’68 318 – keeps it at temp
Was having temperature issues with my 318. Never warms up without a thermostat, 165 deg thermo was running way too hot for some reason. This one keeps the gauge right in the middle.

Sweet
Alright so I’m not sure if it was this product alone but I recently installed this, a new factory radiator, and tuner on my 1993 chevy c1500 350 and the coolant temp sensor stays where it should all the time. I used to have problems in drive thru with over heating or red-lights with my ac on but now it doesn’t go over where it would normally be. Seems good to me.

No parece dramático el aumento de flujo pero se ve de calidad y no es muy caro

Temps still reach 205°F , it lasted a week at 190°Ordered 160°F to see if it will keep temp at least at 180°F
