Gates 31511 cooling system components for the 1991-1993 Ford Explorer 4.0L and other vehicles are a safety release radiator cap that seals and holds pressure in the cooling system.
- The release lever protects against accidental burns by releasing steam through an overflow tube.
- Covers a wide range of pressures, 12-16 psi.
- Can be used for applications with or without coolant recovery systems.
- Constructed of corrosion-resistant, heavy-gauge metal.
Coolant loss at the overflow, a collapsed radiator hose or overheating can mean the cap is no longer holding pressure, though a sticking thermostat or a leaking hose may be behind them, so find the cause before replacing it.
It fits the 1975-1997 Ford F-250 with the L6-4.9L, V8-5.0L, V8-5.8L, V8-5.9L, V8-6.4L, V8-6.6L, V8-6.9L, V8-7.3L or V8-7.5L engine, and the 1983-1997 Ford Ranger L4-2.3L. If your car is not one of these, open the "Vehicles it fits" section and match your own model and engine.
