coolant for cat

[bjs]

I have a buddy out of state that purchased a cat 287b . he wants to know what kind of coolant to run ? said was little low .

What colour is the coolant that's in it right now..?

 

[bjs]

he said green

If it's green the original coolant has been replaced at some time with regular anti-freeze. My vote would be to drain all the coolant, flush the system completely with water, and refill with coolant meeting Cat EC-1 specification. The total system capacity is only 2.8 gallons.

Nige beat me to it. Cat ELC is the best coolant on the market IMO. Had a water pump go out on our 953 at 4K plus hours and while changing it noticed no cavitation or buildup - the pipes were clean as they say. That particular engine has ran Cat ELC since day one.

I have since swapped all of our engines over to ELC.

Just in case he's not aware, coolant that meets Cat EC-1 spec will be red in colour.

BJS check the price of Cat ELC at Yancey, Thompson sells it at about the same price as you can buy green antifreeze at an auto parts store.
