Product Description

180 Degree Thermostat for 1971-1973 Mustangs with a 351C Engine.

Installing this new 180 degree direct relpacement thermostat can prevent serious damage to your engine. Keeping your engine operating at peak performance while maintaining optimum engine temperature is very important. A faulty thermostat could cause loss of coolant flow and incorrect temperature readings. Thermostats are normally around 180 degrees from the factory.

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

After years of service, thermostats tend to stick or provide faulty operation. To keep this from happening, replace the thermostat during regular tuneups to keep everything working properly. Adding new coolant with the thermostat will help keep your engine running at it's proper operating temperature.

Rated 5 out of 5 by from Good quality I always get the right part when ordering but the description calls this a thermostat for a 6 cylinder 351 Cleveland. I've never seen a 6 cylinder 351 Cleveland.
