Replace Air Compressor coolant lines

yeah! you need to drain coolant. may be not all, but more then half.

replacing compressor hoses is not so difficult thing. I do this kind of works myself

 

if you are quick--and do it in your neighbours driveway it can be done
might be better to drain tho

 

my friend did hoses change and spilled some coolant, neighobour's dog drank a bit and died...

 

If this is a true story, friend must be popular with the neighbors...

 

yeah, it is true. coolant is poison, but with sweet taste.

sometiimes dogs die drinking antyfreeze in garages, truck yards.. so if you spill coolant do not let animals drink it.

well, fortunatly coolant is not so dangerouse for us, becouse we prefere vodka

 

You'd probably have an easier time replacing those heater hoses without draining the system than the air compressor lines. You should definitely do it all at once while you have the coolant drained. I'd replace every hose on the thing and be done with it. Take a good look at the oil line going to the compressor too, wouldn't hurt to replace it if it's the original one.

You might save a couple of bucks by getting those lines made at a hose shop instead of the dealer. Might save some time too if Detroit (or whoever) has to order them.

 

i do the same way. there is exavator shop near my work and I use to gove him old hoses and they make all hoses for me, including PS lines, brake lines, coolant hoses.. it is a bit funny to have 750 BAR rated heater hoses

 

I know each truck is a little differant but on mine I just hang a five gallon bucket on my water filter bracket and unscrew the water filter, seems easier and less messy, just have another bucket handy to swap out if needed, this will get the water level down below the air compressor lines and the upper heater hose and should have a cutoff for the lower heater hose.
