Product Description

Cool-Trak coolant test strips is a easy and reliable way to test engine coolant effectiveness. With one simple dip, you can determine an engine's protection against freeze-up, boil-over and acid buildup with a highly effective pH test. You can also use CoolTrak to determine when to send coolant for recycling and to check recycled coolant for effectiveness. CoolTrak has been proven effective with the US military and has been approved for use by the U.S. Postal Service and municipal vehicle maintenance centers across the country.

Yeah, yeah, yeah. It tests freeze protection and acid level. Oh, wait--it DOESN'T test acid level of "orange" (extended-life) coolant. Gee, it'd be nice if a person knew about that BEFORE purchse, since this product isn't going to be fully compatible with newer vehicles; or older vehicles that have been converted to extended-life coolant.

They put that disclaimer on the bottle, but not in the online descriptions.

Works fine when used with the common, ordinary green Ethylene Glycol coolant. There's NO mention of it's suitability when used with Propylene Glycol.

While the freeze & boiling point measurements of this product is very helpful, the pH range of the strips don't help much, if at all. It gives results for pH levels of 6, 7, 7.5, 8 and then jumps all the way up to 11. The range between 8 & 11 is the most critical, as this is where the pH level should be on most engines. I used the strips to test the coolant on my RV's auxiliary generator. My coolant pH level should be between 8.5 & 9.5. But since the strips jump from 8 to 11, there's no way for me to tell if I'm at the correct pH level.

The lower levels of 6 through 8 are measured at close intervals which is useless, as the coolant should be changed in almost any engine if it falls below 8. The makers of this product should have made the measurements more precise ABOVE 8, not below it.

no where in the description does it mention anything about working only for green anti-freeze. Not many cars use green anti-freeze any more. I used it on a Toyota and it has red anti-freeze , it gave me a reading but can't say if it is accurate or not. I am going to change the anti-freeze just to be safe so it was a waste of money buying the test strips. I am quite sure they don't tell you about only working for green anti-freeze because it would limit the number of buyers.

They are not the greatest for the low phosphate low silicate low ph antifreezes. That is because the ph scale is for a more traditional "green" antifreeze.

I change my coolant religiously at the 30k mile or the 2-year mark (whichever comes first as recommended) for my 1995 Nissan Pathfinder. It had been 2 years and I took my truck in for my mechanic's inspection for the coolant change. He told me the coolant was in real good shape and no need to flush it just yet.
Me being me, I was just curious and wanted to test it a bit more for my own eyes. These strips told me exactly what my mechanic did. And, as advertised by the product, in only 30 seconds. Extremely easy to do, 'even a cave man can do it.' I'll be using them again and again and with a set count of 50 it should hold me for a while. Seems to be an accurate and very fair priced product.

Online description of product does NOT mention that it cannot be used with various colored (orange, etc.) coolants, which makes the strips useless for many of the long-life coolants. This is clearly stated on the product - so one discovers it AFTER having purchased it. Did not return - not worth the hassle.

I had an opportunity to test these strips against a pro-grade refractometer. I had an HVAC tech over the other day to help me raise the polyethelene glycol concentration in my radiant heat system (it had become slightly diluted after 10+ years).

Over the course of an hour we compared readings about 7 times as we brought up the concentration. Since he had the more accurate device, I'd call out my reading first and then he'd share his. I was within 2-3% of his concentration readings each time ... and I had a ph reading as well.

Now to be fair, I got better over the series of trials because I could calibrate my readings off of his. But even so, you should be confident that you can be within 5% in a concentration estimate without the benefit of a refractometer (as long as you are not color blind).

But I did notice that the bottle has an expiration date ... as it should, since the chems on each strip won't last forever. I think the exp date gives you about three years, and with 50 strips, you'd need to test a lot of glycol to go through a bottle in that time. So buy a bottle and share it with a friend, and keep your eyes on that expiration date !

Right on the bottle it says the PH measuring pad is not recommended for orange or red dyed coolants. Almost all newer vehicles are specifying orange or red extended life coolants. So this strip is useless for the purpose of knowing when a orange or red coolant should be changed. That is what i wanted to determine. Question: Why doesn't Amazon include such an important limitation in it's description of the product. All is not lost though it does an OK job of determining the PH of the hot tub.
