	Remove/install
1	Open engine hood and raise to vertical position
2	Detach oil cooling lines (7, 8) from radiator		AR27.10-P-0501-03SX
		Before starting work the area surrounding the oil cooling lines (7, 8) on the transmission and the supply line (6) on the transfer case must be thoroughly cleaned in the area around the separation points. Even the smallest dirt particles in the hydraulic components can lead to malfunctions and a total failure of the transmission. A restrictor (6a) and a filter cartridge (6b) is fitted in the connection to the transfer case in supply line (6). The right oil cooling line (7) and supply line (6) are securely connected to each other and can therefore only be removed together.
