I have a safety radiator cap, with the pressure relief lever. When burping the coolant, can I just lift this lever to get rid of the air bubbles without having to loosen the cap? Or should I still loosen the cap until coolant runs out each time?
I know it seems like a dumb question, but I just didn't want to assume things and waste a bunch of time burping. Thanks ahead of time!
You can try that but lever types can develop air leaks and then radiator will suck air when system cools. Some says lever types hit the hood and that can cause problem too but I don't know.

It was a bit confusing, so I made a couple of corrections.
If you're using a" Lever cap" On The Radiator, the Radiator is Lower than the engine, so .... when you lift the lever you will in all likelihood be letting Air IN, not out. That's why you Fill from the back. the only way what you are doing will work, IS, if you jack up the front of the car so it is about 6-8" higher, then try it.
