Nope. There's an oil/water heat exchanger on the bottom of the motor between the block and the oil filter that helps to equalize water and oil temps, but it's not really a cooler.
I built a top mount oil cooler that kinda sits where the old intercooler went in the hoodscoop. Unfortunately it looks like the cooler core has a leak in it!

Time to bring it back to Summit for a new one.
