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.

Cadillac Fleetwood V8-5.7L - Electric Problems - Orlando, Florida
Great mechanic. Very thorough, helped and tried to locate the main problem. He couldn't locate the problem I was having but then again this was my 3rd opinion (1st time with YourMechanic) and to no avail. Took his time and was never in a hurry.

Cadillac Fleetwood V8-5.7L - Cooling System Flush - San Antonio, Texas
It sometimes takes forever to find the right fit for a car owner - - we all know the story. Having to wade thru a bunch of bad experiences, price gouges, and broken promises. All this and all that many have suffered like this ended today with my Experience with Mario. This was the BEST experience I have ever had with a mechanic. Highly knowledgable, extremely polite, very service focused and oriented. No upselling, no change in price. All in all a top-notch customer service experience. I thought for sure I heard my car say "Thanks Mario" when he drove away - - I have been known to have a rude car so I'll say it again - thanks Mario.

Cadillac Fleetwood V8-4.1L - Fuel Pump - Oakland, California
I made an appt. for Tien to come by and replace the fuel pump for my no start diagnosed by him through the inspection I had a few weeks earlier. Tien got to work on the car immediately on arrival. As in many if not all jobs, it turned out to be a more complicated than expected. In the process of changing the fuel pump, he discovered that the new fuel pump was slightly different than the one being replaced and the wiring would need to be adjusted somehow to be able to use the new one. It was amazing to see as he used his knowlege and experience to make the necessary adjustments to make the part work! He could have taken the "shortcut way" which a lot of mechanics would have done. When he removed the old fuel pump, it seems that only the fuel hose part was damaged beyond repair, but the rest of the unit was intact and probably still working. He could have maybe just changed the hose part and left the rest of the old unit as is, but decided to replace the whole unit if he could, pending the wiring adjustment mentioned above. Thanks Tien for a great job highly recommend you to everyone!
