Product Details

Fel-Pro 35278 is engineered for coolant outlet sealing where dimensional accuracy matters. The 1.890-inch inside diameter and 5.9 mm thickness support proper fitment at the sealing surface, helping restore the joint between the coolant outlet and mating component. This part number is used across multiple Toyota platforms, including Toyota 4Runner, Toyota Pickup, and Toyota Supra applications from the 1980s and 1990s. Fel-Pro 35278 also cross-references Gates 33618 for the same application.

Installation Notes

Clean both mating surfaces before installation and remove any old gasket material, corrosion, or coolant residue. Verify the seal dimensions against the original part before assembly.
