Buy one of the coolant strength testers at the FLAPS. Under $10 for a
good one by Prestone. This will tell you the concentration you have now
and then you can calculate what you need to bring it up. After changing,
run the engine to make sure everything is mixed well before testing
again.

Problem is the last guy to refill it used one gallon of antifreeze and
filled it with water.  So how much do I drain and refill with 100 %
antifreeze to get to 50-50?  That�s why the math part.

Thanks
