Friend has a 69 MGC and his temp gauge is moving from N to 3/4 H when he is
doing 70 on the highway. It lowers to N when driving more civilized. Has a
rad that was checked out OK and a new 13 row oil cooler. Thermostat is a 180
and new. Any thoughts?
I had a BMW 2002 that acted like that. Turned out to be a cracked head,
although I supposed a faulty head gasket could do it, too. Does he lose water?
