Hi All! Hey, I know the thermostat temperature is critical to the performance of the 5.0's but what is the best for the 4.6?
i know the factory is a 195, and i think you would be safe with a 180 or 185 which ever it is.....you dont want to go with a 160 though because it can pout the car in open loop and u will be running rich, and gas mileage will suffer..
I had a 180* thermostat in my mustang. It takes longer for your car to get to operating temperatures. It will cool your car alot more efficiently than the stock 195* thermostat because it will be in open loop more. I liked the 180* thermostat in my mustang because in the hot humid summer months my car would run cooler. 180* is the coldest thermostat you should get because 160* in too cold.
