Antifreeze Coolant Tester 8592 (item no. 140305)

Check your coolant in minutes — before the first freeze catches your engine.

The 8592 antifreeze tester shows how much frost protection the coolant in your car still offers. You use it straight at the open expansion tank or radiator, with no tools and no workshop visit. It is the simple way to prepare a car for winter and to re-check the coolant during the season.

Winter coolant check right in your driveway

The 8592 antifreeze tester gives a clear answer on whether the coolant still protects the engine below zero. The check takes minutes and can be repeated every season, ahead of the first cold nights.
