Don,
ELC is not really compatible with the Alliance which is a "low silicate for diesels with added SCA" coolant.
ELC is an OAT-based coolant that does not require the addition of anything for a period of 6 years unless you drive more than 300,000 miles on it.
My suggestion would be to change out the coolant if most of it is OE, as the OE coolants do not have a design life that would still have it in good condition. And replacing coolant is a LOT less expensive than radiators, water pumps, etc.
BTW, here is the part number for ELC Concentrate is: Caterpillar 119-5150 or 238-8647 which is ELC with embitterment.

Brett,
According to what I've read on the subject there is a test strip that can be used to determine if the SCA is ok and if its not more can be added rather than replacing all of the coolant. The parts man at he dealership asked a mechanic if the ELC was compatible with Alliance and he said it was while I was standing there. I believe it states on the bottle that it is compatible with all types of coolants. That was why I used it.
