Cat caught the FLU
2000 Cat C-15 is puking her fluids. Maintenance claimed it was "just the radiator cap", put on new cap, no difference. From a COLD start, within minutes shes puking past the cap thru overflow tube onto the ground. After a days driving she needs 2-3 gallons replaced. She holds a good temp running on flat ground, gets a bit warm (200 +) when climbing, and has kicked on (at 250 deg.) the water warning and stop engine light 3X. I'm thinking injector seals leaking, causing pressure to build in cooling system, but since I'm not the "mechanic" nobody listens. HELP!!

Yes fan cycles on/off. I thought about head gasket too, no oil contamination tho. Possible, yes I know.

From the original post:

You're getting compression leaking into the cooling system. Head gasket is a possibility. I've also seen this caused by an air compressor with a cracked head or bad head gasket allowing air pressure into the cooling system. If the truck's air pressure is at zero when you start it, and then the "puking" starts as the air pressure builds, it could be caused by the compressor.

Cold start, warm restart, doesnt matter. If the radiator is full, shes puking her guts up. Air tanks can be empty or full, doesnt matter. Last run from N Alabama to Chicago, filled er up, when at stop, put 4 3/4 gallons back in. Goes in shop Wednesday, will update.

Sounds like compression leaking from the head gasket. Block check can be used to detect cylinder gases in the coolant. The compressor can be unloaded to eliminate the air in the cooling system problem.
