Holland was going to charge you 400 bucks for a coolant change?

84FC35 Coolant Change - Keith Strehle - 04-02-2007 07:37
Hey everyone, I'm slowly catching up on the maintenance items for my
FC. I don't know when the coolant was changed last. So, I have a
couple questions
Regarding the coolant...
The coolant is bright green. Does that mean it's good to go?
I plan on testing the pH. Should it be neutral? pH-7?
If the pH is good does that mean the coolant is good?
When and if I change the coolant, should I drain everything? Heaters
and all?
Okay, last one. How much coolant will I need to do the job and is
there a preferred brand or color?
Many thanks, Keith

I am changing my A/F as part of some major maintenance. You need to
download the Cat lubrication guide in the file section. There is a
section on coolant. You have a diesel and there are many things more
important than the PH. Bright green indicates that your unit has
regular life A/F. Do you know if it has ever been changed? When? There
are many choices and the Cat document covers them all.

I just bought the coach and the previous owners were unsure about
maintenance and didn't have many records. It has only 36,000 miles but
it is 23 yrs old. So, I don't know the status of the curent coolant?
I'm thinking of having Holland do it for me but thought I should test
it first. Should I use a standard automotive glycol test meter? Don't
want to spend $400 if I don't have to...

Generally what you want to test with is a three-way test strip. Nitrites, glycol
(freeze point), and pH. Nitrites give a good indication of the level of
protective additives.

Yep, figured about 8 to 15 gallons depending on whether on not the
entire system was drained. Makes sense to drain the whole thing to
me. Didn't ask about SCA? Not really sure if I need the SCA?
Drained, flushed, refilled, chassis heat and all. Actually around $335
not includng SCA?

You can use the standard auto glycol test meter for antifreeze to
water ratio. You want around 50% ratio.
You NEED SCA. Cat SCA and test strips, or compatible in the correct
ratio. Too little is bad, and so is too much.
I did research this past week on SCA. Nalcool and Nalcool test
strips, and the NAPA SCA and test strips are compatible with the CAT
product.
The fleetguard brands are more for Cummins. (Just differrent
formulations.)
