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.

Mercedes-Benz CL500 V8-5.0L - Pre-purchase Car Inspection - Lumberton, New Jersey
G inspected a Benz CL500 for me. He found multiple issues with the vehicle and saved me a 2 hour drive to Philadelphia to inspect the car myself. His inspection was very thorough; I was highly impressed. He took the time to make sure that I don't get stuck with a lemon; with his findings, he saved me from a potential costly nightmare.

Mercedes-Benz CL500 V8-5.0L - Radiator - Houston, Texas
If you read nothing beyond this first sentence, just know that Robert is magnificent! On my repair day, Robert showed up promptly at the requested appointment time, sending several heads-up texts prior to his visit. Upon arrival, he very kindly and pleasantly introduced himself, then immediately proceeded to review the requested service and closely inspected the vehicle before bringing out his heavy duty tools. Radiator replacement can be tricky, but Robert tackled it with ease and with a highly professional methodology which can only come from longtime mechanical knowledge and experience. Not only was Robert careful to keep the job site clean and orderly, but he also took delicate care in disassembling components in and around the engine. Once the radiator was successfully replaced and the coolant levels and functionality restored to factory specs, Robert went above and beyond by scanning the vehicle computer for any fault codes, etc. He diagnosed a misfire and tested some ignition components, after which he very kindly suggested what needed to be repaired in the near future. Overall, I will gladly admit that I am very satisfied with the repair work received by Robert. I cannot thank him and YourMechanic enough, as the service received was excellent, affordable, precise, professional and highly convenient. I would highly recommend Robert as a mechanic, as his knowledge, insights, technique and professionalism are without equal.
