Still Have to Change Coolant Every 2 Years?

[RaydaKub]

You can check electrolysis with a multimeter, whether that tells the whole story, I dunno.

Tell me more, please.

In the area I live in used coolant can be disposed of at designated recycle depots.

I change the coolant when the water pump goes bad.

As coolant ages, it becomes more conductive.

Excellent tip ! And easy !

In the distant past, I've seen conductivity vs. lifespan graphs.... somewhere..... so, I can't vouch for those exact #'s in the quick link I found, but they'll probably do as a rule of thumb.....

The junk yards around our area sells old antifreeze taken out cars before being parted out. Guess they figure if it looks green or orange it's good. Sure they don't care as long as they make a few extra $.

Maybe that's a cover up plan for dumping it on the ground. I can't imagine anyone stupid enough to buy second hand antifreeze.

My (4) Kubotas all came with standard green coolant, which should be changed every 2 years. I have always replaced the oem coolant with a hoat (hybrid organic acid) coolant that requires changing at 5 years.
Whatever coolant type is used, I would replace it at the required interval.
