Stainless Steel Engine Oil Cooler (EC140S)
These Stainless Steel Engine Oil Cooler (EC140S) are equally suitable for cooling torque converter, automatic transmission and engine oils. Being water cooled they have the advantage of freedom from accidental damage and also encourage quicker warming up of the oil, a feature which is particularly valuable in cold climates. The tube stack is fully floating so that thermal stresses are minimised and it can easily be removed should cleaning be necessary.
The cooler should be fitted into the engine water circuit between the bottom tank of the radiator and the water inlet connection on the engine as illustrated as below, the radii of water pipe bends should be as large as possible to reduce the pressure drop. Also indicated as below are the approximate capabilities of the various coolers for torque converter applications. This information is only intended as a general guide as the factors affecting the choice of oil cooler are complex. In the case of engine oil applications we are not able to give any general recommendations, but proposals can be submitted on receipt of details of the particular engine.
