This will save you hundreds of dollars over the life of your tires. The interval most vehicle and tire makers recommend is every 5,000 to 8,000 miles, and even more frequently if you have a Front-Wheel Drive, All-Wheel Drive or 4-Wheel drive vehicle.
Add pure antifreeze initially in a volume equal to the water remaining in the system, topping off with a 50/50 mix. â¢ Improper topping off. If you have a low coolant level, the first thing to do is add coolant; the second is find out where the coolant is going.Finding and fixing leaks is critical. When topping off, be consistent. Mix and mark a jug containing a 50/50 mix of compatible antifreeze and distilled or demineralized water.Then use that container for all top-offs.Too many systems get topped off with whatever is handy, commonly pure antifreeze, plain tap water, or...whatever is handy.ix and mark a jug containing a 50/50 mix of compatible antifreeze and distilled or demineralized water.

As for buying pure coolant or a 50/50 mixture...the 50/50 mixture fairly recent. 10 years (maybe it was 20)...you could only buy 100% coolant. And I've NEVER bought the 50/50 mix. Seems like a waste to me...especially since it's the same price. Docnick 2011-02-28 17:27:17 UTC #5.
