ZR-1 Net Registry Forums - View Single Post - "Burping" the LT5 after a coolant change?

Bell Curve · 08-17-2005

During a thread about which coolant to use (Red or Green), someone mentioned "burping" the engine afterward. A reply came that I copied below;

Take a large asprin or any drug in tablet form, pry the thermostat open and use the pill to hold it open. The pill will dissolve, but not before you fill the car without any air gaps, no need to burp it and it won't harm anything.

Whatever you do, don't use the orange crap, it will corrode the system.

I wanted to hear opinions on it and "burping" in general?
