So, I changed the coolant on my caterpillar 320c after running it with dawn dish washing detergent in it to clean for 30 hours.
The problem is......well...it is supposed to hold 7.9 gallons of coolant. I could only get maybe 6 gallons out of it. I could only add 6. I did a 50/50 ratio of water and red coolant.
So...I couldn't get the whole amount flushed....nor add new back.
I kinda blew air through it with compressor.
I undid the hoses in many places.
See when I refilled....I loosened the coolant sample fitting on the coolant tube by the valve cover to let air out as I was refilling. Then I cranked machine and let run for an hour and watched the gauge. It barely climbed at all. Turned on the heater with no fan. Anybody got a cool way to completely drain and refill the coolant? I guess I could think of a few ways to do it...but I'd like to learn a new trick. Please.
I was in a hurry so I just gave up at dark. I guess a couple of gallons stayed in the block..... The machine needs to run in morning so I gave up on my creativity.
By the way....the dawn dish washing detergent...well...it foams so much AFTER draining and replacing that it was aggravating when pouring in new coolant.
The fins in my radiator have a little white fuzz on it....not bad...but a little. Dawn didn't fix that. Should I run a flush chemical? I don't wanna harm it...or mess up the heater core. And what additive would be good to run to prevent cavitation and corrosion? I usually use napa cool etc.....
Thanks
