The OEM recommendation for my Hyundai Genesis Coupe is to change the coolant initially at 5 years (100,000 kms), then every 2 years (50,000 kms). However, I only drive this vehicle in the summer so in a year I might only put 5000 kms on it. Would the time based interval still apply? Does coolant degrade with time AND mileage?
Strangely, the OEM coolant was blue but the genuine Hyundai coolant I bought from the dealership (concentrated) was green. I wonder if the OEM coolant is some sort of super long life formulation while the dealership stock is standard old school stuff? Ideally I would love to use some sort of long life coolant that I can safety go for extended periods of not changing. Most new vehicles seem to have coolant change intervals of 5 years or more so every 2 years seems kind of excessive.
