H3 oil light
1 Answer
I think we have found a fix for this issue on mine. The radiator wasn't working properly...replaced and replaced the oil sensor switch and over a month now, no light on! This took a lot of testing from my guys. The did every test possible to rule out what GM wanted to replace. Starting with a new engine, then a head gasket and cylinder head to other various things at a low cost of 20,000.00. Imagine if I had listened to them. I have Over 145,000 miles on it.
