Gates Engine Coolant Thermostat P/N:34830
Gates 34927 thermostat for the 2015-2020 Ford Mustang V8 5.0L and the 2016-2019 Mustang V8 5.2L controls engine temperature from an integrated thermostat housing. This engine coolant thermostat opens and closes to hold the engine at its operating temperature.
An engine that runs hot, warms up slowly or shows a wandering temperature gauge can mean a stuck thermostat. A weak water pump, a low coolant level or a failing cooling fan can be behind those signs too, so find the cause before you buy. If the thermostat is at fault, this unit replaces it.
It is a thermostat for the 2015-2020 Ford Mustang V8 5.0L and the 2016-2019 Mustang V8 5.2L, and each engine takes one. It meets or exceeds OE standards for fit, form and performance.
