Notes:

• Do not confuse with WL or WLT engines—though similar, the WE has distinct head and combustion chamber design.

• Always confirm the engine code and cylinder head casting number to ensure compatibility.

• Replace the head gasket and use new head bolts during installation to prevent warping or leakage.

• Ensure proper torque sequence during installation for longevity and performance.
