coolant test strip probs??

[dieseldan2005]

I just got some of the fleetguard coolant test strips and did everything they said to do for the test, but the colors on mine won't change. So i added a bottle of the additive anyway cause i wasn't sure when it was done last, but shouldn't the nitrate and the other one change color to show where there at on the chart?

anybody know how to make these things work right?

I dunno, I just dip it in, pull it out and they change. you're supposed to take the reading within 45 seconds of getting the pads wet I think recalling the directions in my mind.. not sure if the coolant has to be hot or cold.

[dieseldan2005]

yeah i tried it 2 times and the same results both times. No color change. Did you take the coolant from the regular tank or did you drain some from the rad pet****?

[Lord Tauk]

Just from the overflow res.

That's really weird, you're positive it's all getting wet?

I've heard these things go bad after a year. Could you have gotten some old ones? I always drain a few ounces from the radiator drain pet****.
Read it within a few seconds and I always double check the freeze protection with a Prestone antifreeze coolant tester. Since I completely trust the old style coolant tester, if the freeze protection doesn't match, I wouldn't trust the SCA or nitrate reading either.

See my reply to your other post on the same problem.

yeah, was that stuff you were talkin about, coolant or an additive?
