cooling system additive

[bucwheat]

What do you guys use for a Diesel cooling system additive. I used to buy something called F-7 but it's not made anymore.

You mean for the anti-cavitation? Fleetguard DCA4. Well, the pints are designated DCA4. Half-gallons are DCA65L, gallons are DCA70L. Best price I've seen is at Ryder Fleet Products.

yep, thats good stuff. also, I wasnt able to find that stuff at my local parts store so i got Wixcool instead, which is also great. Wix Filters 495-24058 - WIX Filters WIXCool Coolant Additive - Overview - SummitRacing.com

good idea to get some coolant test strips too..

I am a fan of Power Service (both white winter and silver summer bottles), but when I plan ahead and get the stuff ordered in from the dealer, I like using FPPF products.

I think the FPPF 'Total Power' product is the poop. It has a cetane booster, anti-gel, water dispersant, injector cleaner, and lubricity improver all in one shot. When summertime rolls around, I go with their 'Lubricity plus Fuel Power." Which has all of the above without the anti-gel.

Edit: Ooops... I didn't realize it was coolant additive you were after.
