Do you carry test strips for Volvo VCS coolant? I would like to check the freeze protection remaining and determine whether I need to change the coolant before winterizing the engines.
We don’t carry test stips, but NAPA or VIP have a refractometer (about $85) that tests nicely.
We don’t tend to use the less expensive hydrometers ($15) as they only work on Ethylene Glycol based
coolants while the refractometer works on all coolants (Propylene Glycol as well – yellow and red).
Besides the refractometer is way more accurate.
