What is the radiator cap pressure test all about?

In a pressurized cooling system like those found on all cars, your car’s radiator cap is calibrated to seal in coolant to a particular pressure point, then allow some vapor to escape once that threshold has been reached. The ejected fluid is piped into the overflow bottle you might have seen in the engine bay. Then, as the engine cools, the coolant level may drop inside radiator. When that happens, a reverse-flow valve in the radiator cap opens to allow fluid from the bottle to return to the radiator. A radiator cap that isn’t working properly may cause too much fluid to escape the system.

Keep in mind:

  • A radiator cap pressure test is quick and simple, and replacement radiator caps are inexpensive.
  • Leaving a defective radiator cap in place can cause damage to the engine.

How it's done:

  • The vehicle engine is cooled before the radiator cap can be removed
  • The radiator pressure is relieved and the cap is removed
  • The radiator cap is pressure tested to specifications
  • The radiator cap is replaced and/or reinstalled to the radiator
  • The vehicle is verified to confirm problem is fixed

Our recommendation:

If your car’s engine overheats, or the overflow bottle seems overly full, have the radiator (and radiator cap) pressure tested.

What are the common symptoms indicating you need to pressure test the radiator cap?

  • Car overheats
  • Car’s overflow bottle fills up

How important is this service?

Not having this safety valve on the car’s cooling system operate properly can over- or under-pressurize the system, leading to damage to hoses, the radiator, and even the car’s cylinder head.

Oldsmobile 98 V6-3.8L - Oil Change - San Jose, California
Kenny was very informative and down to business. Diagnosed my problem, quickly ordered the parts,scheduled a time to come back, and provided the cost all in a few taps of his phone. I thought it was great having him roll up to my driveway and fix my car while I was in the comfort of my home. By the time i got inside I had an email with the invoice and new appointment.

Oldsmobile 98 V6-3.8L - Oil Pressure Light is on - Houston, Texas
The mobile mechanic came. I must say I am impressed! He found my house. He and I started talking. He said he owned two Ninety Eights previously. He was there to look at my Oldsmobile Ninety Eight. He had two Oldsmobile Ninety Eight Touring Sedans. The ones he owned were from the 1987-1990 era. He was describing the floor shifters and they had and how much he liked Ninety Eights, Touring Sedans, and the Oldsmobile Eighty Eight LSS too. He talked about how a family member owned one and how he was fixing his. He talked in detail about the Touring Sedan and the things he loved. He asked me how long had I owned my Ninety Eight. I told him 2003. He told me how he become a mechanic and went to school for it and more. He got into the Ninety Eight and it would not start. He got out and disconnected the battery and rubbed the negative and positive battery terminals together. He reconnected them and the Ninety Eight started! The instrumentation then told him exactly what it was. There is a sensor at the bottom of the oil pan. He said by doing what he did with the terminals, it cleared the computer and reset it. We went underneath the car and he showed me the sensor. He said which one did you replace? I told him. He said you were on the right path. You know what you are doing. You need to replace this sensor and not the one you did. You can get the sensor and replace it because it is clear you know what you are doing and on the right path. He said you also need to replace your valve cover gaskets. They are leaking. I told him I will request him to come back and do that. I am not doing that even thought I can.
