Re: REFLECTOR: oil temp



I have two coolers in parallel with the aft cooler with the control valve.
I put the control valve on the aft cooler so I would still have heat on the
cold days that I don't need all that cooling capacity.

I have a problem of not being able to get the oil temp up to minimum for
take off without overheating the cylinderheads  I have an engine heater on
the engine all the time during cold weather which keeps the engine oil over
100 degrees, but as soon as I start the engine, the cold oil from the
coolers prevents me from getting to min. oil temp prior to cylinder over
temp.  I read my oil temp on the line out to the coolers.
