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.

BMW X5 L6-3.0L Turbo Diesel - Brake Pads Replacement (Rear) - Bothell, Washington
This is my first time using YourMechanic and I've seen mixed reviews about such a service, so I was hesitant at first. However, I researched around and it felt like going with someone like Theodore will help improve my experience. I booked the appointment and crossed my fingers that things will go well. Theodore was spot on. He arrive exactly at 10am in my front door. Had a quick chat about any of my concerns and on he went to do his job. He finished the task expediently. I did a test drive, signed the invoice and off he went. Yes, it was that quick and easy. I had a similar job performed at my usual autoshop about a year ago for the front brakes and it costed me over $600. I managed to get this similar job done for less than $350 total. Saved over $250. And I didn't see any additional advantage of doing this at some shop. In fact, it was much more convenient to do this at my home, where I didn't sit around and wasted my valuable time. Overall, this was a great experience and I wouldn't hesitate to use Theodore again for all my future auto needs.
