Prestone Extended Life Coolant

Only use what is recommended for your specific engine. Do not mix. Do not use universal. Do not rely on color. Its more expensive, but, I prefer pre mix. Never have to worry about minerals or mixture ratio. The engine costs too much to mess around.

Peak Final Charge is the way to go. The only drawback is if you have a hose that blows and you are not in a major area that coolant may not be available. Truck stops and SOME NAPA's do carry Final Charge. I keep 2 gallons of the concentrate in our unit as well as some distilled water.

Buy the Cummins/Fleetwood product. A LOT of places have it or can get it quickly

Maybe Peak final charge.

Check out the newer generation OAT-based diesel coolants.

Looks like they have several offerings styled: "Extended Life Coolants".

Here is another extended life coolant that would not be suitable for diesel engines: http://www.prestone.com/enmx/products/antifreeze_coolant/product_list

Looks good on their website.

I just had my radiator replaced due to the external fins falling off from salt I guess, the inside looked like new, no sediment, not clogging of the tubes, just parfect looking all due to using the ELC, the coach is a 2001 model with 114 K miles.
New radiator went back on with 50/50 ELC & Distilled water.

A quick look at the specs saw no mention of "for diesel engines". For the best answer, look up the Mil Specs for the coolant in your Cummins owners manual and compare to the Mil Specs on the Prestone produce.

There are basically two types of coolants for diesel engines, particularly critical for linered engines like you ISC:

1. Low silicate for diesels with added SCA
2. New generation OAT-based coolant for diesel

Use even an excellent coolant meant for gasoline or non-linered diesels and you will have cylinder wall erosion.

If you have a Cummins engine....just use their Antifreeze. Youll always have someone to call if you develop any sort of problem(s)
