What should the pressure be on a jeep radiator?
General rates of increase are usually 8psi to 15psi. If pressures exceed the rated amount for the cap, the valve will open and release the pressure and possibly coolant as well.
What causes a jeep radiator to overheat?
As the engine heats up, the thermostat opens and allows coolant to circulate through out the entire coolant system. The thermostat can fail by either sticking open, sticking closed, or completely breaking and cause an internal blockage. All these scenarios can cause overheating, no hot air output, or low running temps.
When to take radiator cap off Jeep Wrangler?
Now, if the engine in your Jeep 4.0L Cherokee (or Grand Cherokee, Wrangler) has been running for a while and it’s hot, let it cool down for about an hour, since a radiator cap should never be removed with the engine hot. Please take all necessary safety precautions.

General rates of increase are usually 8psi to 15psi. If pressures exceed the rated amount for the cap, the valve will open and release the pressure and possibly coolant as well.
What happens to the coolant in a jeep radiator?
For every additional pound of pressure the coolant’s boiling point increases by 3ºF. General rates of increase are usually 8psi to 15psi. If pressures exceed the rated amount for the cap, the valve will open and release the pressure and possibly coolant as well. This coolant will be highly susceptible to flash boiling.
What happens when you increase the pressure on the radiator?
The water will expand and create pressure. The boiling point of the water increases three degrees for every 1 psi the pressure goes up. If the pressure goes up 15 psi we add 45 degrees.
What should the pressure radiator cap rating be?
Remember, none of the above running temperatures have anything to do with the cap rating. They are simply conditions of the cooling systems capability, the ambient air temperature, and air flow. Often customers will report their system boiling over at temperatures of 220 or lower and as explained above this isn’t possible.
