How much Green do I need

[Gary Petersen]

2002' Sig with Cummins 500 ISM which, has dirty coolant.

The engine and radiator need to be flushed, and new green coolant installed.

I plan to purchase the concentrate and distilled H2O, to mix my own to 50/50.

How can I find out how many gallons of Concentrate to purchase before, I start this project?

Thanks,

If you replace with green coolant, making sure it is low silicant coolant, if you do not know.

 You should have one of these for reference.

I especially appreciate the reference warning regarding the Low Silicate and the linked document which, gave me the quantity number (11 1/2 gal) for which I was looking.

A big Thank You, comin' at You!

Glad I could help!

 Fwiw, I use a Fleetguard product, ES Complete, with the blue label.

 The best thing you can do is educate yourself on coolant. Also consider carrying a couple of gallons extra with you in your travels, concentrate preferably and a gallon of premixed and if you have to add water to the cooling system use only distilled water, that would also include doing a system flush.

To make sure that I am getting the correct coolant; Does the Blue label ES Concentrated liquid, have a blue color?

With the Fleetguard ES Concentrate, am I correct in assuming I would now use a "blank" filter.

Hey Gary,

   Yes the coolant I used has a blueish tint to it.

   Yes on not using a treated coolant filter, a blank filter would be fine, you should test your coolant every 6 -12 months with appropriate test strips from fleetguard to confirm that it is still good.
