Hi Phil,
Just a guess, but perhaps the viscosity of the oil at 11 above was
thick enough to jam the sender unit wide open and now it is stuck there.
Maybe with heat and cycles it will free up again. Just a guess...
best,
doug

Subject: [Shop-talk] Oil-pressure gauge goes nuts on Suburban.
2004 Chevrolet Suburban. Picked up my truck after it had been sitting out in
the 11-degree-F cold for a while. Started OK. The oil-pressure gauge was
pegged WAY past the end. Stopped the truck after it was warm and went into a
store. Came out and turned on the ignition. Needle went to full scale.
Started the engine and needle went to full-on pegged again. Stayed that way
until I shut it off in the garage. Needle went to zero. Ignition on, back to
full scale. Restart engine, back to superpeg again.
All the other gauges
seem to be acting normally.
Anybody else ever seen anything like this?
