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!

Yes lift the lever slightly until you here the air escaping. Be careful if the coolant is hot as you might get a steam burn.

From what ive seen on here many times, the lever action cap is not recommended ever. Use an OEM type. You can search or go to Ogres Cave.

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.

See my Cave, Radiator Caps and Coolant Fill

It was a bit confusing, so I made a couple of corrections.

Ahhh, so it isn't recommended to use. That's good to know! I will swap it out for the OEM style cap and bleed like normal. Thanks, guys!

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.
