Either the cap is defective or too much pressure is building up in the system. I would replace the cap is it does not appear to be overheating. answer you have a defective radiator cap replace with a new one with same pressure rating as old one
A radiator cap would not cause a leak! However, if the radiator cap is holding pressure, other weak parts could signal issues in need of attention.
Radiator cap
Check valve in radiator cap malfunction, replace radiator cap.
there is no real radiator cap. On the left side of engine compartment there is a coolant jug. This where you would add coolant to radiator.
Hey Willie==If it comes out the cap and not the overflow jug, the cap is faulty plus what is causing it to get hot. 'Check the fans for proper operation. If it isn't smoking white smoke, it probably isn't the head gaskets. A stuck thermostat will also cause it ot overheat. If all else fails, take it to a radiator shop and have the radiator flow tested. GoodluckJoe
The thread on cap on your engine coolant reservoir is your pressure cap / radiator cap ( 16 PSI ) on a 1996 Ford Taurus ( all engines )
blown head gasket. the easiest way to tell is to open the radiator cap while the cars running BUT BE CAREFUL! if theres antifreeze in there it will spray and burn you! but if you have a blown head gasket when you open the throttle the same white smoke will blow out of the radiator cap. white smoke is a sign of a blown head gasket though.
If you have a threaded cap on your coolant reservoir that is your " radiator cap "
No , the " radiator " cap / pressure cap is the thread on cap on the engine coolant reservoir
The radiator cap is on top of the radiator.
Coolant gets hot. Either there's a radiator leak, or you opened up the cap without letting it cool down.
The raiator is a type of system where all fluid is added to the reservoir instead of the radiator directly, look for the reservoir and you will have found your radiator cap.
