Oil Coolers

[Dale Campbell]

I to have the aluminum plates also that my A&P made for the top of oil cooler. I slide it in and put 3 screws in he provided, when the oil is changed in fall. They stay there until spring. With out them my engine oil never got above 140 degrees F, which built water in oil very fast. I flew yesterday to Boston with ground temp at 5 degree F and the oil got up to 180 degree. When you fly in the north they are a must, at least on my normal asperated bird.
