Darryl&Rita Posted August 21, 2022 Report Share Posted August 21, 2022 I'd want to figure out where it went, but to refill, wait until it's cooled down, then add back to the "Full Cold" mark.

Jaydrvr Posted August 22, 2022 Report Share Posted August 22, 2022 Find out if you're running conventional coolant or extended life. Conventional is typically green, while extended is often red. You can use the green to top off the extended, but then you loose the extended life properties. Jay Quote Link to comment Share on other sites More sharing options...
Darryl&Rita Posted August 22, 2022 Report Share Posted August 22, 2022 Good call, Jay. Mixing in the wrong blend can also create mud in the cooling system, I'm thinking of the early Dex-Cool blend being topped with green, and absolute chaos resulting.

hemsteadc Posted August 22, 2022 Author Report Share Posted August 22, 2022 (edited) It looks kinda reddish. What's the trick to getting the metal cap off? I've twisted it open but I can't pull it off. Looks like some kind of rubber thing in the middle of the cap may be stuck. I've seen youtubes using a wrench but I don't want to twist it too far.

Is it maybe a quarter turn cap? Push down while turning? Also, if you don't know the age of the coolant and it doesn't look clean, you might consider just flushing and refilling. Cheap preventative maintenance. Jay Quote Link to comment Share on other sites More sharing options...

I don't think silicate dropout is any longer much of a problem. My understanding is the newer formulations are designed to avoid that. As I recall, it typically occurred by over treating with additive packs. Jay Quote Link to comment Share on other sites More sharing options...

I was getting concerned about coolant because on my last two tows I noticed it hitting 212 before the fan came on. In years of ownership I've never paid that close attention to the water temp, maybe that's normal for this truck. Edit.. I've tried twisting, pushing.. it won't come off. I'll see what SC has to say. Hours later I still can't this thing off. Edited August 22, 2022 by hemsteadc Quote Link to comment Share on other sites More sharing options...
Twotoes Posted August 23, 2022 Report Share Posted August 23, 2022 I currently have a coolent leak. It turned out to be the pump in the AquaHot for the engine pre heat. Turned off both the intake valve and the recirculate valve to isolate the pump till I can replace it.

jenandjon Posted December 19, 2022 Report Share Posted December 19, 2022 You can get coolant that is compatible with everything. It is a yellowish green. We started getting that in our farm shop. Otherwise, we had 2 barrels of coolant for various pieces of equipment. We had old-school green for the old stuff. A barrel of red for the trucks and a bunch of 2 1/2-gallon jugs of John Deere brand for the newer equipment still under warranty.
