Coolant Bubble
I replaced my coolant the other day and now I have an intermittent "Low Coolant" light. I assume that I have a bubble in there somewhere.......my question is, how do I get it out?

Look through the tips, you'll find one on how to purge air. What year do you have. One old trick that works is take the radiator cap off and let the engine run untill it reaches temp. If the air bubble reaches the top, it just vents out. keep an eye on the level when it gets hot, it will drop when the air is released.

I just put a penney on the throttle stop and that kept the RPM's around 2K. Maybe it was a nickel. It does force the air out and heats up the engine so the thermostat will open. You must wait wntil the thermostat opens to get the air out. You'll see the water in the radiator tank begin to flow when it opens.
