Caterpillar 312B 9GR00432- I posted this before but did not make it clear that -the hydraulics- are what's overheating only when traveling. Hydraulic temp runs normal when digging. Ambient temperatures in the 70's & 80's F so that should not be a problem. High volume of air flow thru cooling coils. Hydraulics overheat and after a while then also raises the water temperature. Water goes up just slightly over the middle of the gauge but not really hot. I don't know how to change the subject or modify the older todays post.
