Oil Cooler - Toyota Supra User Booklet

2. Oil Cooler

The 2JZ–GTE engine is equipped with a water–cooled, multi–plate, full–flow type oil cooler between the oil filter
and oil filter bracket, to cool the engine oil. The oil filter bracket is made of a lightweight magnesium alloy.
3. Oil Jets
One of the methods adopted by the 2JZ–GTE engine to cool the piston is to spray engine oil on the bottom of the
piston, on the side of the connecting rod. Accordingly, there is an oil jet provided for each cylinder. The oil that is
sprayed onto the bottom of the piston enters the piston hole located directly above the oil jet, and flows into the oil
gallery (an aluminum pipe which is cast into the piston) to cool the piston from the inside. The oil will then come
out from the hole located opposite to the hole through which is has entered the oil gallery.
