Antifreeze And Or Additive What Kind?

[Mbmaring]

I put a block heater in an 1999 E7 eteck drained out the antifreeze and wonder what kind of antifreeze I should use and if I have to put in an electrolysis prevention additive like you do for the old cummins. I have some extended life antifreeze made by peek will that work?

Antifreeze sold for Class 8 use will normally have the additive already in it. Up at our dealership, we use Houghton Security red antifreeze that already has the nitrite SCA (supplement coolant additive) in it for all shop jobs.

By far, this link gives the best information on not only what your coolant needs to have, but WHY.

I've used Polaris Labs for oil and coolant analysis.

They seem to have it togather.

I had a little training on coolants (through Polaris) on cooling systems and after seeing some

of their examples, as well as my own experance I know that coolant is much more than just

something you cuss when its in your oil pan!

One thing I picked up on a long time ago was to use de-ionized water when changing/adding

coolant. (Read the artical)

It will actualy clean up a dirty system somewhat.

If you spend $6-8.00 per gallon on coolant (times about 6 gals), another $6.00 or so for de-ionized water

to mix with it is not a big cash out-lay.

I am big on NOT using tap water!!!!

Another additive I've used is Nal-Cool.

That purple stuff.

Adds many miles to a cooling system.
