How can I test for a bad radiator cap?

Alternatively, you can use the OEMTOOLS 27065 Radiator and Cap Test Kit to test for pressure faults and leaks from your radiator cap. To use this device, you need to turn off your car and wait for at least 30 minutes before you remove your radiator cap. Connect the pressure gauge or tester to the cap adapter and screw it tight.

What happens when you open the radiator cap?

This will cause air pockets to get inside of the heater core, thermostat, and radiator hoses. As a result, the engine will start to overheat because it cannot sustain a temperature that is consistent. Warning: Never open the radiator while it is hot!

What should the pressure be on the radiator?

A radiator cap is the part of a vehicle responsible for containing engine coolant and ensuring that the cooling system remains under pressure. Ideally, car cooling systems should maintain a pressure of around 13 to 16 PSI. The radiator cap ensures that this pressure remains constant.

What causes coolant to overflow from the radiator?

Your problem may simply be a loose or damaged cap not keeping coolant where it needs to be. The radiator cap is designed to allow access to fluids in a ‘closed’ system. The coolant used to cool the engine does so at maximum efficiency when kept at specific pressure. Check your owner’s manual for proper cap replacement.

What are the symptoms of a bad radiator cap?

The radiator cap ensures that this pressure remains constant. There are several symptoms of a bad radiator cap like leaking coolant, the appearance of white streaks, and hose bursts caused by coolant pressure fluctuations. Excessive pressure causes cooling system component failure while less pressure could lead to the liquid coolant boiling off.

When to remove the coolant recovery reservoir cap?

If you engine does start to overheat, it is important to note that you should not remove the coolant recovery reservoir cap or the radiator cap. After you stop and you turn your vehicle off, you should wait at least 20 minutes before opening the cap.

Where is the coolant recovery tank located on a radiator?

The coolant recovery reservoir takes this place, and any coolant that escapes from the radiator due to pressure will flow through a discharge tube and into the recovery reservoir. The coolant recovery tank is made of white plastic and located near the radiator. You will be able to see how much fluid is inside of the reservoir.

When to check coolant level in the radiator?

If you have 2 fans when you turn on ac both should be running. Also check coolant level when cool in the radiator and make sure it is full. Also are you sure you have a proper coolant to water mix?
