Hi all, I have an 01 xc70 120k miles.
I recently purchased a scan gauge to monitor my engine temperature, I'm becoming obsessed. When driving at highway speed my gauge reads at 188f, in stop and go traffic it can read up to 225f. 225f seems high, should I be concerned?
What is the optimum temperature range?
I have also noticed my cooling fan doesn't start,if at all, until 220f. Is this an issue? Can the cooling fan cut in point be adjusted in anyway?, I have recently replaced the cooling fan with a used one, the previous owner had done a bad jerry rig fix.
My cooling obsession is a result of the transmission issues I'm having, the car shifts beautifully when the engine is below 209f, above that temperature all sorts of crazy things happen.
Any insight would be appreciated.
