If you are
only measuring one point for each; probably best to measure coolant out of the
engine (water pump housing), and oil temp going in.
If you have
additional temp measuring channels; as with the EM2, then some additional data
can be useful in diagnosing cooling systems behavior. I measure oil temp
out of the engine at the filter mount (which I have on the outlet side from
the engine), and at the adapter block going back in. Gives me the delta
T of the oil cooler. I also measure temp on the outlet leg of each of
two radiators, in addition to the engine out at the water pump. Gives me
the delta T for each rad.
I also have
outside air temp, and exit air temps on the oil cooler and each rad. So
I have complete heat balances on the cooling system. If everything is
working just fine; it’s just extra data. If not, that data will help me
diagnose how to fix a problem.

Re: Oil and WaterTemps
Where are you guys
measuring the oil temp? I believe some are putting temp sensor on a fitting
at the oil filter. Is this correct? Does everyone sense the water temp at
the water pump housing?
