Re: Best Method to Burp Cooling System
This may sound a little crude, but what I've done in the past is to fill the system up to to the radiator cap opening and/or the thermostat opening like Marcus said, and then raise the front end of the car 18" to 2 feet up in the air with a floor jack, and then top it off again with more coolant. Then after bringing it to operating temperature and running it for awhile, I let it cool down for a good 4 hours, and then raise the front end up in the air and top off the radiator again, and it's good to go. This ensures that your radiator neck is the highest point of the system. Or if you happen to have a driveway that's on a hill, you can just do the same with it parked there.
