LR3/Disco 3
Cylinder Block
The cylinder block is an 'Enclosed V' design, which provides an inherently rigid structure with good vibration levels. A low
volume coolant jacket improves warm-up times and piston noise levels; the longitudinal flow design of the jacket, with a
single cylinder head coolant transfer port in each bank, improves rigidity and head gasket sealing. The right hand cylinder
bank is designated as bank'A' (cylinders 1 to 4), and the left hand as bank 'B' (cylinders 5 to 8).
Engine Data Locations
Engine data is marked at three locations, two on the cylinder block (shown) and one on the engine front cover, which
consists a label displaying the engine number. Component diameters are represented by alphabetical and numerical
codes; keys to the codes are in the Service Repair Procedures (SRP) Manual.
