How many psi should the radiator cap be specified for?

My friends truck didn't have heat so he replaced his radiator cap and the hoses begain to leak but the heater worked I believe the cap has a stamp that says 13psi (i'm not positve) could that be correct?

    13-15 PSI is the normal operating pressure of the cooling system. No-heat issues with the V-6 can usually be tracked down to air pockets in the cooling system. If you need further information, please get back to me.

My 1997 buick park avenue, is getting hot. upper radiator hose gets under extreme pressue, stem coming from radiator hose/radiator inlet, leaks coolant only after shut off??


Normal pressure is 16 psi controlled by the radiator or coolant tank filler cap. Sometimes a cap fails to hold the proper pressure this is most noticeable at engine shut off, water and steam blow out

2000 Dodge Durango getting over heated


Never use a used radiator... check electric cooling fan, and air must be purged out of the radiator / cooling system after refilling it, this can be a little difficult. are you sure that it is not leaking coolant from somewhere else, which would cause the overheating.?

Have water leaking in front of motor behind a c compressor.checked and replaced water pump,still leaking.is thier a freeze plug behind a c compressor?


You don't say which engine you have but if I were you I would get a cooling system tester and test your cooling system. Very simple to use you just remove your radiator cap and install the tester and pump it up to the PSI listed on your radiator cap. You may be able to rent one. After you pump it up watch for the leak and pinpoint it. Not knowing which engine you have, I'm guessing the 4.3 liter. I believe there is a heater hose connector in the right hand side of your intake manifold. Those are common for leaking. I'm not sure where your compressor is located. Also you may have an intake manifold gasket leaking which is common. With the tester you should be able to trace it down. Also it is possible that your new pump could be faulty or it it possible that you didn't get the gasket surface area clean?

1998 Buick Skylark is over heating


You need to check the radiator cap for air leaks and also try having the radiator Flushed as you could have plugged fins inside the radiator, causing the radiator not to cool the antifreeze.

2001 Honda CRV radiator leaking


I had the same problem and traced it to the joint between the plastic bottom and the metal body. This is a common fault, you would new a pressure test to confirm.
