Product Details

Fel-Pro 35448 is a thermostat housing gasket for vehicles that use a coolant outlet or thermostat housing seal in the cooling system. Fel-Pro focuses on vehicle-specific sealing solutions, using materials selected for the application rather than a one-size-fits-all approach. This helps support a proper seal on service jobs involving Buick Century, Buick Skylark, Oldsmobile Cutlass Ciera, and related GM platforms.

Follow the vehicle service procedure and torque specifications for the thermostat housing to help achieve a proper seal.
