Description
New copper-nickel/cupronickel oil cooler for Ford Lehman marine diesel engines. This cooler will replace either engine or transmission cooler (purchase two coolers if you need to replace both). It is manufactured by Seakamp Engineering, and is a replacement for Ford Lehman part number 2C212 (2C212CN). View the below chart for model applications:
| Engine Model | Lehman Model | HP | Displacement | Cylinders | Series |
|---|---|---|---|---|---|
| 2701E | 4D242 | 80 | 242 cu. in. | 4 | Dorset |
| 2711E | 4D254 | 80 | 254 cu. in. | 4 | Dorset |
| 2712E | 4D254 | 80 | 254 cu. in. | 4 | Dorset |
| 2704E | 6D363 | 120 | 363 cu. in. | 6 | Dorset |
| 2713E | 6D362 | 120 | 362 cu. in. | 6 | Dorset |
| 2714E | 6D380 | 120 | 380 cu. in. | 6 | Dorset |
| 2715E | 6D380 | 120 | 380 cu. in. | 6 | Dorset |
This cooler comes in primer gray. The dimensions are 2 inch diameter body, 1 inch water ports, 9 inch core length, 12.5 inch overall length, and 3/8 inch NPT pipe thread for oil line fittings. For maximum cooling, coolers should be setup so that water and oil flow in opposite directions. This cooler does not have a zinc. Look for Seakamp 29133CNZ if you need a copper-nickel with zinc cooler.
If you need any other Ford Lehman parts, such as an expansion tank, heat exchanger, water pump, or elbow, or would like the copper version of this cooler (2C207), view all Ford Lehman listings here.
