How can I tell if my HG is going???

[Steve885]

Not sure what to look for I'm having some cooling issues..yesterday I did the burping the system trick withe a 2 liter bottle cut and the tiny bubbles never stopped..the water didn't smell like exhaust..but I'm a novice mechanic and am not sure....

If you have constant bubbles, theirs either a leak in the system or a HG.

I have a tool that tests the gas in the cooling system for Co. It draws the gas through the tool, and bubbles it through a blue fluid. If the fluid turns yellow, the cooling system has exhaust in it.

Perhaps you can find someone in your area who has such a device.

Or buy it for 20 bucks.....


I have never had much luck with those things.

Do a compression and leakdown test
