136Driving and operating
operations for wading , involving
checks for water contamination, at
the earliest opportunity.
Service checks after wading
Check for the ingress of water into the following:
â– Brake fluid reservoir
â– Air cleaner element
â– Engine
â– Transmission
â– Axles
â– Interior of vehicle
Renew any lubricating oil or hydraulic
fluid that has a milky appearance,
indicating contamination with water.
Cleaning
Clean the vehicle thoroughly and as
soon as possible after driving off-
road.
Do not let mud remain dry on any part
of the vehicle as it becomes abrasive and can damage paint, glass, seals,
bearings and brake components. If
left to build up, mud can seriously
affect the airflow through and overmechanical components and cause
localised overheating and failure of
parts, especially in the engine
compartment.
Ensure the radiator core and the area
between the radiator and intercooler/
oil cooler (where installed) is cleaned, to maintain proper cooling air flow.
Check the radiator and cooler cores
for blockage (sand, silt etc.).
Check the tyre treads.
Clean and check the mechanical
parts of the vehicle, particularly the
following areas:
â– Driveshafts, including sealing bellows
â– Front brake calipers, pads and discs
â– Front suspension
â– Clutch fork sealing bellows
â– Rear brake calipers, pads and discs
â– Rear suspension
â– Fuel tank and underguard
â– Breathers, axles and fuel tank
â– Load sensing valveâ– Transfer box and underguard
â– Engine oil pan and underguard
Observe the following: â– Do not spray high-pressure water directly at the vehicle seals
â– The wheels must be removed to clean all mud and stones from the
brake calipers and to check brake
pad wear
â– The areas on the upper side of the underguards must be cleared of
stones, to prevent damage to the
engine oil pan and the fuel tank
