Mustang Thermostat 180 Degree V8 289/302/351W 1965-1995

180 Degree Thermostat for 1965-1995 289/302/351W V8 Mustangs.

Features a copper "hat" that seals against a bypass restrictor plate inside the block. This closes the bypass circuit when the thermostat opens, so that all coolant has to go through the radiator. This keeps the temperature from fluctuating too much, thus causing overheating.
