Rotella ELC NF

[johnmyster]

Any qualms with switching to ELC-NF? Looking for maximum protection against heater core sludging, long term.

Not keen on mopar purple based on limited availability.

Currently filled with prestone dex cool, but will be taking the system down to do water pump and lower radiator hose. Obviously, will do a good flush and probably use a descaling cleaner (perhaps fleetguard restore or similar, Ford VC-1) in the process.

while Mopar seems to have a love for their own coolant
the engine manufacturer Cummins specifications for what coolants are acceptable would include that Rotella ELC.
you should be fine.

FWIW, I use that same Rotella ELC in my Kubota turbo diesel tractor and it works well.

I’m assuming the differences in ELC and the NF version are minimal? Pick one and stick with it?

Not coolant related but you guys probably know, I changed the oil and filter on my B21 Kubota, and I put in 3.5 quarts of oil. Then I noticed they should only have 3.2 quarts. Looked at dipstick, the lines I thought were the fill and low lines might be the fainter lines on the side opposite the heavy lines with numbers in between. Will it hurt anything to run it aclittle on the full side?

realistically you can use just about any off the shelf EL coolant you can find in a Cummins engine,if you had a Cummins Shop manual available you'd see it.. its just Mopar has that proprietary coolant specification that no one prints on their label except Mopar.

I currently am running good old Prestone Long Life one size fits all coolant.

Honestly, I think any special spec coolant is nonsense, as long as you clean and drain all the old stuff the compatibility issue should disappear.
I can't think of any material used in any engine that is any different from a different brand.. they all have to make contact with aluminum, brass, copper, iron ,plastic, rubber etc so where does the difference truly lie? Most likely in the engineers making one choice from many.

Thanks for the input. Peak Final Charge Pro seems to be the latest and greatest in HD ELC, and was on sale. It’s also available most places including wal mart. I’ll be going that path.
