Description

The Dorman 902-2030 is an engine coolant thermostat housing designed for select GM vehicles. It is constructed from durable metal with a natural finish for corrosion resistance. This housing features a 1.25-inch outlet port, two 0.313-inch mounting holes, and a 45-degree neck angle for precise fitment.

This part includes a gasket for a leak-free seal and an air vent (bleeder valve) to remove trapped air, helping to prevent overheating and maintain optimal engine temperature. Bolts and the thermostat itself are not included.
