Engine running hot in the summer? A few XJ's were equipped from the factory with oil coolers -- notably the Canadian and European 650 Secas and the 900 Seca. The 650 oil cooler is a direct bolt-on for the 750, but the larger 900 cooler will also fit, if you fabricate your own mounting braket for the cooler.

Don't forget, the cooler requires an adapter that bolts on between the oil filter and the engine, as well as the hoses to run from the cooler to the adapter. The 900 and 650 adapters are identical, but the 650 hoses are longer than the 900's, to accomodate the larger cooler. Pictured here is a 900 cooler mounted on a 750. Click on the pictures to enlarge.
