If the radiator grille is clogged with foreign debris and dead insects, it is necessary to blow the grille with air using the counterflow method. The automatic transmission oil cooler is installed in front of the engine cooling system radiator, but can be mounted with the cooling system radiator in one unit.
The power steering and air conditioner radiators are installed in front of the engine cooling system radiator.
Removing the radiator of the cooling system must be carried out in the following order. Unscrew the drain plug at the bottom of the radiator (see fig. 3.137), drain the coolant only from the radiator and remove the fan shroud.
Remove the expansion tank of the cooling system.
On vehicles equipped with automatic transmission, pull the lock (1, fig. 3.141) up and remove its heat exchanger from the radiator circuit board.
Leave the heat exchanger pipes connected.
Disconnect the engine cooling hoses. Loosen screws and remove clamp (1, fig. 3.142).
When installing the clamps, tighten the bolts with a torque of 10 Nm (1.0 kgf·m).
Remove the sealing strip between the radiator and its cassette. Unscrew the bolt on the radiator on the right and left side and remove the radiator (pic. 3.143) cooling systems, moving up.
Attention! The radiator fins have very sharp edges to reduce airflow resistance. There is a danger of injury.
Installing the radiator should be carried out in the reverse order, while it is necessary to check the technical condition of the radiator hoses and rubber supports. Insert the radiator together with the rubber pads on the left and right sides into the brackets.
Replace damaged plastic guides. The tabs of both plastic guides must be securely fixed in the holes.
Install the automatic transmission heat exchanger with new seals; during installation, the retainer should snap into place with a characteristic sound.
Fill the system with coolant, bleed it and check the system for leaks. Check coolant level and top up if necessary.
