Caution: When carrying out any installation work, particularly in the engine compartment due to the tight layout, the following must be taken into account. Lines of all types (for example, fuel, hydraulic, activated carbon canister, cooling systems, refrigerant circuits, brake system lines and hoses, vacuum), and electrical wires must be laid as they were originally laid. To avoid damage, ensure sufficient free space to all moving and hot parts. When the engine is warm, the cooling system is under pressure. If necessary, relieve the pressure before repair work. Hose connections are secured with spring clamps. When repairing, use only spring clamps. When installing, lay the cooling system hoses without stretching them. Make sure that they do not touch other components (observe the markings on the radiator pipe and hose).
Cooling system elements installed on the body
- 1 - Cooler, after replacement change the coolant
- 2 - Sealing ring, replace if damaged
- 3 - Fitting, to remove, disconnect the clamp
- 4 - Spring clamp
- 5 - Cooling system hose
- 6 - Radiator hose, upper, to the nipple on the cylinder head
- 7 - Expansion tank. Check the tightness of the cooling system
- 8 - Connector
- 9 - Lid. Check for leaks. At a pressure of 1.4-1.6 bar, the safety valve in the lid should open
- 10 - 5 Nm
- 11 - Plastic inserts for mounting screws
- 12 - Bracket
- 13 - 5 Nm
- 14 - Air intake radiator fan "V7", with cooling fan control unit "J293". When replacing, the radiator fan "V7" and air intake may only be replaced as a set. Heat shields must be installed to prevent damage to the radiator grille from the effects of thermal energy from the exhaust system. Tightening torque of heat shields: 3 Nm
- 15 - Bracket for connector
- 16 - Connector
- 17 - Latches
- 18 - Coolant hose, lower, to thermostat fitting
- 19 - Routing hoses
- 20 - Radiator outlet coolant temperature sensor "G83"
- 21 - Coolant hose, lower, to thermostat fitting
- 22 - Connecting pipe, to remove, disconnect the clamp
Cooling system components installed on the engine (thermostat related)
- 1 - Connecting pipe
- 2 - O-ring, replace
- 3 - Spring
- 4 - Pusher, do not tilt it when installing
- 5 - Thermostat. Do not mix up the thermoelements! Start opening: thermoelement (in the lower picture): 80°C, thermoelement (in the top picture): 96°C
- 6 - Coolant temperature sensor "G62", before removing, if necessary, relieve pressure in the cooling system
- 7 - Mounting bracket, check the reliability of the fastening
- 8 - Thermostat housing, 10 Nm
- 9 - Lip seal, replace
- 10 - To the expansion tank
- 11 - Connecting nipple
- 12 - Coolant pipe, to remove, remove the thermostat housing, to remove, remove the compressor
- 13 - Coolant pipe, to remove, remove the thermostat housing, to remove, remove the compressor
- 14 - 5 Nm
- 15 - From the radiator below
- 16 - To the radiator from above
Cooling system hose connection diagram
- 1 - Expansion tank
- 2 - Intake manifold
- 3 - Heat exchanger heater
- 4 - Thermostat housing
- 5 - Engine oil cooling radiator
- 6 - Cooler
- 7 - Cooling system circulation pump "V50"
- 8 - Turbocharger
- 9 - Cylinder head/cylinder block, after replacement, drain the old and fill in new coolant
- 10 - Autonomous heater, additional equipment
