Hi, My 2002 Subaru is one of those that are subject to head gasket problems. So, maybe I can avoid the problem by keeping the antifreeze in good shape. Chem testing is one way, but i saw a review from someone for Wicks Chem strips in which those gave similar results for 4 -year -old antifreeze and new stuff.
So, does anyone know of a good way to test the solution - one indication of validity is that new and old solutions yield different test results.
I'm also looking into measuring Voltages and I've posted a separate question for that, along with my initial results.
