Extended Life Coolant

[wimberleyman]

I have a 2001 DP with 3126b Cat. I want to convert the coolant from conventional SCA to Peak Final Charge Global Extended Life coolant. I had originally intended to drain the radiator and refill with Peak ELC (about 9-1/2 gallons). However, according to the Peak Final Charge website I can simply drain out one gallon of the existing coolant and add one gallon of Peak Final Charge Extended Life converter and achieve the same results. The cost difference is approximately $60 versus $160. It sure makes a lot of sense money and labor wise to me.

Has anybody in the forum done this?

From doing this on Ford diesels, that is pointless.
Drain it ALL. As much as you can, flush with tap water until clear, then flush with distilled water quite a few times to get all deposits out.
Then drain as much water as you can, refill with HALF your systems capacity in CAT EC-1 rated coolant, then top off with water, and that achieves a true 50/50 mix.

X2 half the battle is getting started and actually doing the job. Do it right the first time and its done. Why be concerned that you may not have a proper mixture.
