"When you are burping your coolant the first thing you do is you fill it up all the way with the engine running and fill the reservoir as well and as the engine heats up you will see bubbles come out and sometimes you will hear a burping sound but as soon as the bubbles stop coming out and the coolant is at a level, is all the way up then you're done burping your system. The easiest part to find will be the overflow reservoir which will say add coolant and it will have lines that say full hot or full cold and another place that you can find the coolant is in the radiator and that is where we are burping it from is by removing the radiator cap and checking the coolant level inside the radiator itself."
