No more trying to cut and weld -16AN fittings to crusty old thermostat housings!
SpeedFactory Racing -16AN Cast Thermostat Housings are designed to replace your factory thermostat housing and allows you to easily adapt -16AN hoses and fittings to your engine's cooling system. All SpeedFactory thermostat housings have provisions for the OEM cooling fan switch and engine harness ground wire.
Complete your -16AN cooling system conversion by pairing this housing with a SpeedFactory Racing Upper Coolant Fill Neck, found in the cooling system section of our online store.
Note: -16AN hose ends are large and may require adjustments to other items such as fill necks, scattershields, etc for clearance.
