[TR] TR6 Oil Cooler

[robert rudolphi]

Hello All,
I am considering adding an oil cooler (13 row) to my 74 TR6. TRF has them on sale and now may be a good time to purchase. I run 20-50 and really only drive the car in the summer. I have noticed a drop in pressure as the car warms up to around 10-15PSI at idle. My questions are do I need to add a thermostat? When changing the oil how to you get old oil out of the cooler, or do you need not worry about that? Any other concerns I should be aware of.
Thanks in advance for any feedback.
Robert
