Cool. And yes, good point on water in fuel.
I know you're a very experienced Vanagon owner so assumed coolant
level was fine but I've had the coolant low light come on while
coasting down a long long steep hill. But in my case, as a less
experienced owner-operator, in fact, the coolant was low.
;^)
Just a WAG though but do you think power fed back through the cluster?
Has your van been upgraded to the later style coolant low module?
