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.

Land Rover Discovery V8-4.6L - Exhaust Manifold Gasket - Menlo Park, California
Khoa showed up a little early and after the pleasantries, immediately went to work on my car. Double checked his diagnosis amd went about his business of replacing some gaskets. Within an hour it was all done and the car as back to its proper self. Khoa worked fast and assessed any other possible issues to look out for. Explained the overall longevity of the work performed. A real pleasure having Khoa help out with my car issues.

Dwight is very polite and professional, and he did a great job on the front drive shaft replacement on my Land Rover. I am so impressed with this company and it is because of individuals like Dwight who represent Your Mechanic in such an oustanding way. I have already scheduled some additional repairs and Dwight will be taking of those for me as well. I highly recommend him to anyone seeking quality repair work for their vehicle. Thanks for all your help today Dwight!

Michael

Land Rover Discovery V8-4.6L - Crankshaft Position Sensor - Las Vegas, Nevada
This was a simple part replacement that was anything but simple! Foreign cars are usually a challenge, but there was barely room to do the work. Michael never once complained and never tried to reschedule (even though it got dark while he was working) even though he still had another customer, and this took much longer than expected. As someone who has worked in the repair industry (appliance), I appreciate a tech of his caliber and I respect his strong work ethic. This is the first time I have used this service, but I will be requesting Michael for any future work I may need to have done.
