Fel-Pro 18-21 Ford F-150/15-21 Mustang/11-14 Edge Engine Coolant Thermostat Housing Gasket

A coolant thermostat housing gasket for the 2011-2021 Ford F-150 and the 2011-2021 Ford Mustang. It has one job: seal the thermostat housing so the coolant stays in the system. If the old one is weeping, this is the part that stops it.

Why Upgrade to a Fel-Pro Thermostat Housing Gasket

Per Fel-Pro, here is what this gasket brings to the job:

• Designed for the repair environment, meaning a housing that has already lived on the truck or car for years.
• Built to deliver a reliable seal on the troublesome applications, the ones where the last gasket did not hold.
• Designed for imperfect sealing surfaces. A mating face that is no longer perfectly flat is what this gasket is made to cope with.
• Manufactured with proprietary materials the brand developed for real-world repair sealing.

Fitment Notes

Fits the 2011-2021 Ford F-150 in Base trim, Raptor (2017-2021) and Tremor (2021). Fits the 2011-2021 Ford Mustang GT, V6 (2011-2017), Boss 302 (2012-2013), GT350 (2016-2020), Bullitt (2019-2020), GT500 (2020-2021) and Mach 1 (2021). Does not fit the Mustang EcoBoost. [VERIFY: the title reads 18-21 F-150 and 15-21 Mustang while our fitment data reads 2011-2021 for both, and the title also lists an 11-14 Edge that is outside this store's scope; confirm the year range before you order.]

Install and Honest Talk

Be honest with yourself about what this part is. It is a seal. You will not feel it, hear it, or see it once the housing is bolted back down. The whole benefit is a coolant leak that stops, nothing more. The brand says the gasket is made for imperfect surfaces, but a gasket is still only as good as the job around it, so pull the surface prep steps and the torque spec from your vehicle service manual before you start. What comes off the vehicle to reach the housing, whether the housing itself comes off, and whether the coolant has to be drained is not spelled out here. [VERIFY: install steps, hardware, torque spec, whether an instruction sheet is in the box, and what comes off the vehicle.] What else you need: your vehicle service manual is where you find out whether fresh coolant, sealant or a new thermostat is called for alongside this gasket; nothing here confirms it either way.

When it ships
