Pressure Test Radiator Cap Service

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.

People say the nicest things

David was knowledgeable, professional and thorough. I will have David do all my future car repairs.

Whitney went above and beyond in solving my issues. Extremely friendly and extremely professional! Thanks, Whitney!

I have to be honest, this was the first time that, I have EVER felt 'at-ease' around an auto mechanic. Jonas was thorough and straight forward with me about the issues; gave me a quote directly after doing the diagnostics on the car and, as it turned out, it cost me less than the original estimate. When does that ever happen with auto repairs ?? He was friendly, informative and knowledgeable. You folks made the whole experience convenient and painless. I'm "sold" on the "Your Mechanic" concept. I'll probably never take my car again to a traditional mechanic !! Jonas was a pleasure to deal with !
