Radiator, Remove and Install (Vehicles with Power Steering and Air Conditioning) Depressurise cooling system by opening of closure cap on coolant compensation tank.
 Remove, Disconnect Remove air guide pipe. Disconnect wiring harness plug from temperature switch I (1), temperature switch II (2) and from fan motor. Remove wiring harness from fan shroud. | 
|
Unclip refrigerant line from bracket (1) and unbolt refrigerant line bracket from exhaust manifold (arrow). | 
|
Remove, Disconnect Loosen high pressure line from power steering pump until it can be moved slightly. For access, turn high pressure line towards engine. | 
|
Loosen fastening bolt (1) of clamp at power steering compensation tank. Remove compensation tank from bracket and lay aside.
 Important! During these operations, the power steering hydraulic system remains closed.
Remove, Disconnect Unbolt radiator bracket from left and right side of air deflector panel. | 
|
Remove, Disconnect Remove dipsticks for engine oil and AT fluid, if present, from guide tubes. Unbolt upper fan shroud fastening bolts from radiator (arrows). | 
|
Remove fan shroud. Push radiator carefully forward into air deflector panel, pull fan shroud out of lower brackets and remove upwards with fan motor (see illus.). | 
|
Remove, Disconnect Additionally on vehicles with AT: Close off hydraulic fluid hoses for fluid cooler (this is integrated in the water radiator) with commercially available hose clamps (1) and remove from connections at AT. To prevent hydraulic fluid escaping, close off connections with suitable plug (2). | 
|
Remove left and right coolant hose and hose to coolant compensation tank. Collect escaping coolant. | 
|
Remove, Disconnect Pull radiator out of lower rubber buffers in crossmember and remove upwards. When replacing the radiator, transfer hydraulic hoses for oil cooler (1) and temperature switch I (3) and temperature switch II (2). Use new seal rings.

Insert radiator into lower rubber buffers in crossmember. Install coolant hoses to radiator and, if present, fluid cooler hydraulic hoses to automatic transmission. Remove hose clamps from hydraulic fluid hoses. Install fan shroud with fan motor. For this, insert fan shroud into lower bracket and fasten with both bolts on top to radiator - 4 Nm / 3 lbf. ft. (see illus.). | 
|
Install, Connect Align high pressure line to power steering pump and tighten. Insert compensation tank into bracket, tighten clamp bolt (1).
Tighten (Torque) High pressure line to power steering pump - 28 Nm / 21 lbf. ft. |
|
Install, Connect Disconnect left coolant hose, right coolant hose and hose to coolant compensation tank (see illus.). |
|
Install, Connect Connect wiring harness plug to temperature switch I (1), temperature switch II (2) and to fan motor. Fasten wiring harness to fan shroud. Install air guide tube and insert oil and fluid dipsticks. |
|
Important! Route wiring harness along fan shroud so that it cannot be damaged by rotating fan. | 
|
Install, Connect Clip coolant line into bracket (1) and attach coolant line bracket to exhaust manifold (arrow).
Tighten (Torque) Coolant line bracket to exhaust manifold - 22 Nm / 16 lbf. ft. |
|
Top up and bleed cooling system - see corresponding operation. Ensure that anti-freeze is adequate down to -30 ° C / -22 ° F. For vehicles with automatic transmission - check fluid level - top up fluid if necessary. Use special fluid Dexron ® - II D.... |
