Working off bugs on my new car.
My Smiths coolant temp fluctuates all over the place. It normally sits at 90, then spikes erratically to 110/120/130 in a matter of 2-3 seconds, then after a while, it comes back down just as quickly to around 90. I’m driving very conservatively while getting everything sorted out. Gauge problem?
The Smiths
oil temp reads consistent 80.
Also - I have a “shiny” surge tank/expansion tank mounted to the front of the engine, but I don’t see an Over Flow Tank (black canister) anywhere. Problem?
