Using Coolant Test Strips

[shertex]

I thought I would entertain myself by testing the coolant in my three Benzes. Two of them have Zerex G05; one has Zerex G48.

The test strips I got are Fleetguard 3-way test strips. They test glycol/freeze point, molybdate, and nitrite.

I understand how to do and read the test. What I'm uncertain about is whether these test strips are a good way to test my particular (Zerex) coolant.

Maybe I'll give Valvoline tech support a call next week. But I thought I'd check with you guys to see if you have any insights.

I should probably just change the coolant on all three. But, as long as I have the tests, I might as well see what I can learn.
