AFTER REMOVING the engine and transmission under trays, we first drain the engine oil. This job is always done early in the service because it’s most efficient to drain the engine oil while it is still hot, when it will be less viscous and thus drain more quickly and completely. But we wear gloves and take care to avoid the hot fluid as it is released. We’re using a professional oil draining vessel here, otherwise it’s important to be sure a suitably large container is available to collect the oil and transport it safely to a waste disposal site. While the engine oil is draining, we progress with all the other underside jobs and checks.
The fuel filter shown here is on an early model. On later models a smaller filter is located on the top of the gearbox crossmember, right hand side.
When checking the steering tie rod ends, if an M12 nut is fitted, a torque wrench is used to confirm tightness is 76 Nm. This does not apply to vehicles fitted with larger M14 nuts.
The condition of the suspension bushes is critical to good ride and handling qualities. They need to be inspected carefully for delamination, splits, and leakage from fluid-filled hydraulic bushes. The engine and transmission undertrays need to be unbolted and removed to drain the engine oil and check levels and the fuel filter.
