Coolant loss

Yahoo Message Number: 91675
Finally happened to us. Driving down 60 in Tempe, AZ when I got a stop engine warning, followed by the engine shutting itself down. Coasted to the side of the road, temps at 233 degrees! Let it cool and tried to add coolant. It ran out as fast as I was putting it in. I started it and got off the freeway. Crawled underneath and found the heater pump leaking. Called a mobile tech and had it bypassed. My question is, to get moving again he put in four gallons of tap water. How long is it OK to run like that before I flush and refill with ES Compleat? I am heading to San Antonio and need to get there. We won't be in freezing weather.

AL,

Consider converting to OAT (organic acid technology) coolant. No water filter needed, no SOC requirement (install a dummy filter WF2070?), OAT is good for 150,000 miles.
Peak Final Charge found at NAPA in red label (premixed) or black label (100%) and mix with distilled water.
A system cleaning may be needed. On your coach there are two pepcocks - one on radiator and one on engine, so draining is easy. If you see very little white flakes coming out after a fill and drain with soft water, then you are ready for filling with Final Charge.

Fred,

I Googled the OAT Coolant and it does look interesting.... but would that void any warrant either by the manufacturer or personal warranty you might have?

Coolant should be mixed 50/50 with water. Just drain out about two gallons and refill with two gallons of straight coolant. This won't be exact but it should be close enough considering how many total gallons of coolant are in the system.

Don't know what engine you have; but, both Cummings and CAT make their version of the new OATS technology coolant and they are both fully certified for those engines. My 2006 CAT came with ES Complete and I have considered switching to one of the CAT coolants for convenience when the time comes but so far my coolant analysis test are coming back satisfactory. It is also recommended that you use a cleaner when switching which adds to the cost. Both the ES Complete or OATs version are going to give you 5-7 years of service. The OATS is more environmentally friendly.

After a bit or research, and help from IRV2 Cummins section and specifically member Spike45 (retired from the Cummins/Fleetguard) I went with Final Charge OAT. His point was that it is more readily available in major Truck stops, like Pilot. So getting some for topping off if needed is easier. I carry a gallon of the 50/50 pre mix with me.
I will also note that I am seeing consistently lower temps by about 5-7 degrees.
I see not downside to this. Just make sure your shop gets you a good flushing. I paid my shop to do a final flush with distilled water that I brought into them from the store in two gallon containers, before adding the Final Charge.
Also be sure you get the dummy coolant filter cartridge, as SCA additive is not needed.

Best of luck,

Dan......I am running the Cummins 8.3 ISC. 'Final Charge' is an OAT coolant and is fully compliant with the requirements for Cummins, Cat, Mercedes and several other diesel manufacturers. You can find the full skinny in the 'Peak' link that I included in my original post.

If your cooling system is already in good condition, as mine was, by using the converter there is no need to endure the flush procedure and expense of discarding many gallons of existing coolant.

To my knowledge, no other HD coolant offers this advantage.

The only thing I did, besides adding the converter, was to replace my SCA filter with an untreated filter.
