Green oil Pres light never goes off

[Clembs]

hey i have the problem of the green oil light never going off in my 2a. It comes on after the truck is warm then stays on. The gauge seems fine and not too high pressure.

Any suggestions.

A new pressure sensor is very cheap. First clean your contacts though.

Hello there,

Is this an Ex-MOD veh.?
Sometimes the shuttle valve in the oil cooler can become jammed, causing "groaning" on idle and the oil light to trigger.

Les,
Is that is what they refer to the military moan? Can a replacement shuttle valve be purchased?
