Review on ๐ŸŒก๏ธ Engine Coolant Thermostat Water Inlet Assembly by GM Genuine Parts - 15-10412 by Jimmie Trotto

Revainrating 5 out of 5

This is the original replacement thermostat for LS1 engines. .

This is an OEM replacement thermostat for LS1 engines. It's identical to the one the dealer tried to sell me for $66. Note that this applies to LS1 with OEM water pumps. If you have replaced the water pump or have an 04-later engine, a new separate case version will be made.
