[Fot] Was: Oil Cooler or Oil filter first? Now how to ID flow out the adapter?

[Kas Kastner]

Taking the oil temp form the oil pan lets you see the see the oil temp over
time and that tells you if something needs attention. When it goes to 300
degrees as it did on my TR-3 and not allowed a cooler by the regulations,
you take out the gauge and carry on.
