Description
Radiator caps from Motorcraft are crafted from heavy-duty zinc plated steel and high-quality plastic, both resistant to rust and corrosion. Stainless steel pressure valve springs maintain the calibrated pressure for a maximum service life. These Motorcraft radiator caps include a rubber pressure valve gasket, and are able to withstand high temperatures and deterioration caused by coolant chemicals. Any accidental cap removal can be prevented with the “positive low-pressure” feature.
