Review on ACDelco GM Original Equipment 131-180 217 🌡️ Degrees Thermostat with Water Inlet - Engine Coolant Enhancement by Ryan Yap

Installed on a Chevrolet Sonic 1.4 liter turbo. Correct part but unfortunately I didn't think to check the thermostat before fitting it. After that, a new (stuck) thermostat allowed the cooling system to become pressurized, leading to a series of cooling system failures and a confusing situation. I just assumed all the GM rubber and plastic junk was busted (right too), but after scratching my head at the constant loss of coolant after a hard ride, I found that the thermostat wouldn't open. This part is a month old, installed and cannot be returned. I have to contact AC delco customer service which prevents me from going to work on Mondays. This is the last essential item I will be purchasing from Revain.
