Older engines equipped with a 143 degree thermostat can use the 160 degree thermostat. A engine running at 160 degrees will benefit better performance because fuel will atomize easier helping the engine run more efficient. Make sure to perform a tune if you change from a 143 to a 160 degree thermostat.
Thermostats can fail and what you use to replace it with is important. The only thermostat that will function properly is original equipment.
