Review on 🔥 ACDelco Pro 180° Engine Coolant Thermostat with Gasket - Model 12T55D by Committed Schmidt

Works like a Delco part. 180 degrees is the wrong temperature for my truck. Thermostats are not to blame at all. Highly recommended, however 195 degrees is more appropriate for most applications. Using this thermostat in hot weather can reduce air conditioning efficiency if you have a clutch fan, and lower temperatures will also reduce your vehicle's heating efficiency in cold weather. I've also found this thermostat to open earlier than 195* which extends the warm up cycle in cold weather.
