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.

BMW 750iL V12-5.0L - Serpentine/Drive Belt - Plano, Texas

I highly recommend Adam to anyone needing work to their car or truck. I own 2 old BMW 750iL 12 cylinder sedans. I'm talking 25 and 28 years old. They both have been in storage for about 6 years. One of them had a broken fan belt which I called Mobile Mechanic to send some one to replace it. The person they sent was Adam. Adam was on time for our appointment. He called the day before to introduce himself and disgusted with me the work to be done. Upon his arrival the day of our appointment, he was very polite when he introduced himself to me. He then went to examine my car and what needed to be done in my presents. After his examination he informed me that my water pump may had seized up and it was what was causing the belt to break. He suggested there also may be other things wrong such as the fan clutch that is attached to the water pump may also be froze up. He suggested that I not put the belt on but take it to a garage for further examination. We agree to this and he left without charging me anything. What an honest guy. I did take his advise and the next day had the car at the garage and they found that Adam was right. Both fan clutch and water pump froze up and that is what caused the belt to break. Adam not only saved me the cost of replacing another fan belt which would have broken if he replaced it but also the possibility of getting stuck on the road when the new belt would have broken because of the other 2 problems. Adam was honest enough to inform me of the possible additional problems even at the cost of him not getting the original job he was sent to do. When I get the other car out of storage it is my intent to call Adam to check it out and let me know what needs to be done.

I lost the keys to my 1997 Chevy 1500. I got a replacement lock cylinder and keys. I had to drill the old one out to be able to turn it to the start position to release it and remove the old lock cylinder. I put the new one in and now there's no resistance when I turn it to the start position, none of the dash lights up and the radio is on at all times. I was careful when drilling to be sure I didn't wreck anything. don't believe that I did but I don't know what the heck is going on right now. What I mean by no resistance is that there does not feel like there is a spring or anyting to return it to the Run position after I turn it to start. Nothing kicks in like the fuel pump, windows and locks don't work, blower fan or anything else that should when the key is on. Thanks for any help!
