Hi everyone. I need help with my 2004 Cat 257B, slk00416. It has right around 1600#. Before the answer from the title is head gasket, here's a background..
I recently sent off an oil sample to Fabick cat. The lady in the lab said my numbers indicate absolutely no coolant in the oil at all. I actually purchased everything I need to do a head gasket before I got the sample results back, but never did the change because of that. It is not puffing any smoke and runs fine, so I don't suspect coolant into the cylinder. It will drain an overflow tank of coolant in 2-3hr of use.
Problem number 2, I have not had heat in the machine since I bought used it at 1400#. I figured maybe the heater core could be leaking so raised the cab and all is dry up there. The shutoff valve above the engine is open, and line going to the heater core (I think) gets hot, but the other line (I assume return) stays cold. I assume this would mean a blocked heater core?? Both high and low speed of the fan work fine, but always cold air no matter what temp control is set on. I got the center duct out and shop vac/blew everything out really well. There was quite the mouse nest in there.
Maybe these are related, maybe not, but I do seriously appreciate any help or feedback anyone may be able to offer. Thanks in advance!
