Before asking the question, I live in Central Louisiana, for anyone from East Texas/Louisiana in general you can understand why I am going to ask the question. It can get over 100 degrees here with humidity in the 75+ percent range, and for that, months on end.

I'd like to add an auxillary oil cooler, has anyone done this and if so where did you tap your pressure lines? If not, I'll go it alone and post my own pics, then report on before/after engine oil temperature differences.

X2 on this. since our oil filter is not the typical screw on.

I know the LE5 and LNF share the second gen Ecotec block design. And I know the oil cooler was removed from the LE5 because it was determined it was not needed. I'll assume same is true for the LNF and that it's not needed.

LNFs and LSJ already have an oil cooler.

IMO let it be, I am sure 100+ degree weather was factored in when the engine was designed and tested.
Having your oil or Auto trans fluid too cool isn't the best idea either.

Cooler it is, the thicker it is. Thicker is not always better.

Really? Where is it located? Is it a coolant oil heat exchanger somewhere on the block?

Yes, look down at the driver side of the engine below/next to the oil filter cap. It's a coolant to oil heater/cooler exchanger.

Not necessary unless you're road racing. Even then, it could be arguable, you'd have to take the oil temps. If it's under 300, I wouldn't touch it.

I'm gonna sit on this and wait till we have our first true summer day, measure it and get back to you guys. I'm not convinced the built in cooler is enough.

The LNF has a good oil cooler on it. You don't need to over build this part.
