Does anti freeze evaporate over 5 years? or would a reduction be caused only by a leak?

Answer 1

a leak if in the vehicle that long, but you should'nt be keeping it in the vehicle for that amount of time. you should be changing it out once per year.

it's a fact that some will go down due to evaperation by it cooling off a very hot engine.

Answer 2

No body uses a 100 percent mix, the water will eventuially evaporate, but could be a small, minute leak!!! also not a good idea to go more than 2,3,years between changes, looses its, properties, also a lot of conditioners stop working

Answer 3

Anti-freeze/corrosion inhibitor based on ethylene glycol will get used up in preventing corrosion and will loose it's potency.

In general the cooling system should be flushed every 2 years and re-filled with new coolant.

It is absolutely crucial that different anti-freezes are not mixed, use the same brand. UV will destroy any pre-mix that you might have for topping up, so store in the dark.
