Just in case someone needs a test kit ($69.95 includes shipping) www.rxauto.com/block-test-kits.htm

I took a quick look at the test kit. The kit looks to be a vacuum bulb for getting a test sample, a small mixing jar and a small bottle of liquid catalyst.

I confess I didn't go searching for the process by which this kit works (yet). But a replacement bottle of catalyst is $12.95. Couldn't I buy a bottle of that and use my own mixing chamber? Granted it must be inert but seems simple to me.

Quite a bit of savings.

Yeah, I dunno why they charge so much for them.
They just check for the presence of CO2, right?

You can buy the test kit at NAPA for $49.95.

The way it works:

- Pour liquid into the "mixing chamber"

- Start car with cap off your radiator surge tank

- Put the tapered end of the "mixing chamber" into the top of your surge tank - making sure that the level is low enough that you do not suck up any antifreeze into the chamber - you are only checking for the presence of HCs, in the void in the surge tank.

- Put the bulb at the top of the chamber and pump - while the engine is running still.

If the liquid changes yellow you have HCs in your coolant - a very good (actually very bad) indication that you have head gasket issues.
