coolant question

[Shimon]

It's probably Fleetguard ES Compleat (which is a Cummins product as DieselPower wrote). It's a very good diesel rated coolant w/SCAs. You can buy the Fleetguard test strips which will let you know the freeze point and SCA level (nitrite & molybdate).

I don't know who makes it for them, but NAPA sells a 50/50 premixed antifreeze (distilled water) that is yellow in color, and goes in all makes and models. I like it 'cause it takes out the guessing of mixing, goes in anything, and isn't very expensive. I use it in all my cars and trucks at 20 thousand miles after their first coolant flush. I'll put it in my tracor when I flush the coolant at around 250 hrs. Another thing is it can be mixed with any other coolant too. I think it may be made by Prestone but not sure.

It's probably not a diesel rated coolant...meaning it doesn't have SCAs or DCAs (supplemental or diesel coolant additive) which is specifically added to reduce the detrimental effects or cavitation in diesel engines. If you don't know I'm talking about, use your favorite search engine and search for "diesel cavitation" and you will have plenty of interesting reading. This is not a problem that happens overnight or even after 20,000 miles...it takes a while but when it does happen the affects will ruin the engine. It's a long term insurance policy.

If you want to know if the coolant is rated for diesel engines...it will say so on the bottle. It will also say made for heavy duty trucks or engines. Not light duty trucks. Also look for the specifications on back of the bottle from engine manufacturers or ASTM (see attachment).

Glad you mentioned that.
