Questions for the PROs of trucking/mechanics.. Coolant pushing out.

Is it boiling when it hits your overflow tank? Ought to do a pressure check on system for right psi. Could be as simple as a wore out cap on radiator and as bad as a leaking head gasket depending where its coming from.......thats a drag tho.

 

My vote goes for blown head gasket lol I think more info might be helpful tho.... where it's leaking?...while running? when it's not?... running temp...as cruisin thru said could be as simple as a bad cap

 

It could be that your thermostats are stuck.It just depends on were it is leaking from.If it was a head gasket you will know.P.S. your handle is weird. I don't feel comfortable responding to a pretty Boi trucker. 10-4 .......

 

Is there oil in your radiator? Can you see where it is pushing the coolant out? Could be anything from a cracked liner, head gasket, to some thing with the compressor. They can put a gauge on the fill cap and test some things.

 

What would Oil in the radiator indicate?

 

Oil in coolant would probably be a blown oil cooler. First thing I would do the bottle test to determine if the head gasket needs replacing. If not head gasket I could be oul cooler sending oil or injector cups mixing coolant with fuel

 

I'm with 4legged, head gasket leak. That pressure pushing the coolant out has to have an origin somewhere in the engine, and what else is there?

 

Air compressor!

 

Pushing cooling out is either over heating-confirm with temp, or air compressor-confirm by disconnecting air discharge line, or head gasket-confirm by combustion gas in coolant tester.
