take the cap off and check this look under the cap and see if the rubber seal is broken or it looks worn but if in doubt replace it a mechanic has tool for connecting to radiator to check cap pressure. but if you think radiator cap is the problem, just buy a new one they cost under 10 bucks. if that is the problem, it is sure cheaper than going to a mechanic
What else can I help you with?
Where is the radiator cap located on the 1990 Jeep Cherokee How do you add coolant with only uncapping the overflow and no radiator cap?
I believe the 1990 year still had the sealed system. So there is no rad cap. You can add fluid by pourig it into the overflow bottle with the vehicle running the coolant will be sucked into the system. No radiator cap exist in the 90, 91 model. You add the coolant to the coolant container (The coolant container cap is the equivalent of the radiator cap, (pressure device))and the palstic container is under pressure all the time. Be carefull when you want to open it after the car has been running. After those year models, Jeep discontinued the use of the pressure container and went back to tha radiator cap and remove the pressure coolant container.
Where do you find the radiator cap on a 1989 Jeep Cherokee?

Where is the radiator cap located in a 2002 Jeep liberty sport?
The radiator cap is actually on the plastic overflow bottle located on the passenger side of the firewall. It is pressurized while it is hot, so, use extreme caution there. Your best bet is simply to let it cool before removing the cap. *On a side note* If you are adding a radiator or cooling system sealant, Do not add it to the overflow jug, instead, remove the upper radiator hose (drain out a bit to ensure there is room in the system for what you are adding) and add your sealant there, re-attach, and then start the engine. I hope this has helped, good luck!!
How do you remove air from radiator?
Allow the car to cool. Remove radiator cap. Add water or coolant to fill radiator. Start engine leaving cap off. check to see if coolant is circulating in radiator. Locate upper rad hose, and squeeze to move air bubbles out, or to ecourage circulation. If large air bubble works its way out, add coolant to fill. Once coolant starts to expand and spill out, replace cap. Watch temperature gauge to esure the problem has been rectified. You may have to repeat this procedure.
What would cause a jeep Cherokee radiator upper and lower hoses to collapse?
If they are collapsing after the engine is off, the rad cap is bad. The cap needs to allow pressure back in as the engine cools off.
Why are the radiator hoses sucking inn?
Low on coolant and/or a faulty radiator cap.
What are symptoms of Faulty radiator cap?
Overheating due to coolant going to the reservoir and not coming back to the radiator because of the bad cap.
Would a radiator cap cause a car to overheat?
to add to this, a big YES,on the radiator cap .the radiator cap needs to be specific pressure rating. radiator caps do wear out. also the cheapest fix to start It is doubtful a radiator cap would cause a car to overheat. Common overheating causes are insufficient coolant, leaking coolant (into or out of your engine), faulty thermostat, blown cooling fan fuse, faulty fan temperature switch ( sender ), faulty fan, or a faulty fan relay.
Why is your car using lots of water?
It is leaking coolant or the radiator cap is faulty.
Why is my 2003 Oldsmobile alero overheating?

Could be, worn bearing/seal in water pump, loose hose clamp, faulty hose, faulty radiator, faulty gaskets, faulty heater core, faulty freeze plugs in engine block, faulty radiator cap, cracked cylinder head,
What happen when a radiator cap does not retain the pressure?
When a radiator cap does not retain pressure, the coolant can boil at a lower temperature, leading to overheating of the engine. This can cause damage to engine components and potentially result in a breakdown. It is important to replace a faulty radiator cap to prevent these issues.
How can you tell if your water pump go bad?
I presume you mean car water pump? If the water pump is faulty the car will over heat and the temperature gauge will go up. Make sure that there is enough coolant in the radiator, the radiator or the hose pipe is not leaking and the radiator cap is not faulty, as all of these faults can cause overheating. Once you have excluded these then you can blame the water pump.
Can not replacing the antifreeze cap and driving your van cause the head gaskets to blow?
Yes, but indirectly. Without the radiator cap in place, or using a faulty radiator cap, you run the risk of overheating the engine, which can cause head gasket failure.
Why should you replace the radiator cap?
You should replace the radiator cap if it is leaking coolant, not sealing properly, or showing signs of damage. A faulty radiator cap can lead to issues like overheating, coolant loss, or air entering the cooling system, which can cause damage to your engine. Regularly inspecting and replacing the radiator cap can help prevent these problems and maintain the efficiency of your cooling system.
