hi i just bought a 6x4 diesel unknown to me someone by passed the auto thermostat for the radiator fan with a manual switch. (the switch didnt work when i tried it until i tore it apart and learned what it actually did) After running the unit on some hot days in PA it began to over heat, I thought it was a blown hose or leaking radiator but came to find out about the manual fan switch. Now when I run the gator both the red glow plug light and the amber light next to it both come on intermittently now when I run the machine for 5 or 10 minutes then they go out but will come back on again after awhile. The dealer over the phone thought I had a blown head gasket. Does this sound right to anyone, because I surely dont want to tear it apart for no reason at all. Thanks in advance Phil
