coolant change

I would check with Gillig-- call them with your VIN.

Buy lots of premix antifreeze. Drain the system and start adding premix antifreeze until it is full. Return unopened antifreeze to store for refund.
Make note of how much you put into rig for next time

Call CC. They have it in their records

Please explain with pre-mix how you achieve a 50/50 mixture given that a DP will have 4-5 gallons of residual water (hopefully distilled water in final flush) in the 5/8" diameter lines from engine to heater core, heater core and back to engine?

I always recommend buying concentrate. Determine total system capacity. Final rinse with distilled water. Add 50% of total volume as concentrate and just top off with distilled water. NOW, you have a 50/50 mixture with far less risk of an air lock than any other method.

Da thought here but would you not want to back flush the system, rather just drain and refill. Or is this my old school showing through?

Last month I was inspecting under the power systems of our coach and found several of the radiator hoses expanded and very soft, looking like they needed replacing. The antifreeze was green short life stuff which kind of surprised me as my big trucks have had red extended life in them starting many years ago. I drained the radiator, engine block, transmission cooler and removed the heater hoses up at the heater core and drained them. I collected all of it into buckets so it could be an indicator as to how much was removed. After replacing all the suspect hoses I flushed the entire system in the same manner 4 times. As the removed antifreeze was just under 9 gallons I purchased 5 gal. of concentrate red extended life antifreeze and put it into the expansion tank, I went up to the front and removed the hoses to the heater core again until they both flowed red. I connected one hose and added two gallons (measured in the gallon jugs) so that the heater core was filled with antifreeze and reconnected the hose. Put 2.5 more gallons of water in and it was full.

I ran the engine at 1500 rpm to get the temp high enough to open the thermostat and circulate the mixture through and to mix it. After this I tested and the mix is good to -38. I also bought a gallon of premix to add later if needed.

This took me a day and half to get done but my peace of mind is worth it.

Thanks, Sully
I didn't know that CC was available for info since they went out of business. Will google for the phone#.
