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.

Audi A4 Quattro L4-2.0L Turbo - Automatic Transmission Fluid Service - Mountain View, California

Mark was going to replace the transmission fluid and fix a torn rubber cover of the drive mode selection stick. Having opened up the car he realized that he got a wrong filter part for transmission. This was not his fault (apparently yourmechanic did not ). So Mark had to come again and do a lot of extra work (for no additional pay). He also tried to glue the torn rubber. Somehow he put far too much glue and glued together parts which prevented the drive selection stick from going into some modes. He also somehow managed to leave unremovable superglue on the steering wheel. When I contacted him he came to separate the accidentally glued parts. He managed to fix the sticking but as a result also the part which was supposed to be glued disconnected again. He then told me he is going to look into replacing the part. He did not get back for two weeks. After I reminded him he said he could not figure out the part and said he'll get back to me. But after another week I just went to the authorized dealer and got it fixed. I also checked online and the part was very easy to find on audiparts.com
