did that and I'm not loosing any also filled the bottle with half of water and dont seem to see bubbles of overflow one small constant bubble but stops oil doesnt look murky or milky cant see anything on the ground either
If the leak is new, and not rapid, it takes a while for oil to saturate with enough coolant to change the color of the oil. Ask me how I know
Put some shop towels or something like that under the air tank drain. Pull the air tank drains. See what comes out. While the air drier gets most of the water, coolant can sneak by some. Coolant will have a very sweet smell, and feel slippery.
Did anybody suggest transmission cooler? Some trucks use a coolant to oil heat exchanger. If its leaking, it'll start filling your transmission. Takes a minute to pop the fill/level plug out of the transmission and see if its majorly overfull.
Bubbles may be at high rpm. Try it again and bump the idle up. You can leave the bottle empty, bump the idle up and check it. Or run the truck and keep an eye on the bottle. I hope not but worst case, could be pitted liners, and the coolant is going out of the stack. If this was the case you would see white smoke at start up, as the coolant would leak in the cylinder. Same if your injector cups were leaking in the cylinder. How much are you loosing? And how long before you have to add?
well news update been driving it over 450 miles yesterday I filled up tanks with fresh diesel and a bottle of Lucas knjector cleaner on each side for 2 days no white smoke at start up Nymore and no coolant loss but air tanks getting filled but very slowly I think compressor might be pulling coolant into tanks maybe but checked this morning no coolant loss
That is some good news. keep an eye on it. I know it sucks, but if you have to put a new air compressor on it, that's a lot cheeper than some of the other problems that it could have been
