Can you test Dex-cool with a standard Antifreeze tester? I mean the kind with the turkey baster bulb on the top and the arrow that floats to the protection temperature. I know its just a density tester and wasn't sure if Dex-cool has the same density as other anti-freeze. The tester says "Tests All (ethylene glycol) Antifreeze".

Please lets not start a thread about the virtues of Dex-cool (a.k.a. Red Death), etc. Just trying to learn how to work with it.

I would say use the tester, Specific Gravity of Dex is 1.13, Green stuff is 1.12.

I have tried Prestones Ethylene Glycol (sp?) float guage on the dex-coolant and it didn't work. I dont know if it was a bad gauge or the coolant isn't compatible with the guage.

Prestone says to use the test strips to test thier Dex-Cool coolant. I think test strips are also needed for Propylene Glycol coolants.

Yes for PG coolants, I happen to have some of those test strips because I have it (Amsoil PG) in my 93 Lumina winter car.

btw-The test strips have an expiration date so be careful of what you buy.
