Review on 🔧 132-55 ACDelco GM Original Equipment Engine Coolant Thermostat by Terence Dardant

The thing is scrap. This is surprising as most AC Delco parts I have ordered from Revain have been reliable. Brand new out of the box, they had a slight defect (kink) on the outside diameter. This resulted in it not fitting properly in the cutout in the crossover, and coolant leaking everywhere. Also with a new seal and the right torque. Also, the main function of opening and closing on temperature doesn't work, which drove me crazy trying to find the source of the problem. Quality control is obviously an issue when it comes to this product.
