ANTIFREEZE TESTER

DOES THE JOB FAIRLY CHEAPLY.

Saved me over £100!

At the last service my garage informed me the antifreeze in my Mazda CX3 was out of spec and should be changed. I know that it was tested a year ago and found this hard to believe. Bought this tester and guess what....antifreeze was 100% up to manufacturers specification! That saved me £100 they had quoted for the job! Money well spent on this item.

Antifreeze tester

Arrived as promised on time we'll packaged. This tool tests the antifreeze coolant with six coloured discs that rise in a tube after drawing the coolant by pressing the rubber ball to create the suction action. There was no actual detail or how to use the scale on the tube. A company that sells A product should provide details stated full and instructions to use.

Not accurate readings,leaks

I always buy the same anti freeze and mix it at 33% and have done this for about 40 years like this.I, purchased this tester and tried it at different ratios of antifreeze and water,,you can see from the pics it measure tap water the same as 30% and it only made any movement until I made a 50%mix.its not accurate,and it leaks ,buy those little pippet ones they are better.not happy with this purchase
