Attention! Replace the radiator on a cold engine. In addition, when carrying out any work near the fan, to prevent its arbitrary activation, it is necessary to disconnect the wire from the negative terminal of the battery.
Read the warnings in sec. 2.
Disconnect the wire from the negative battery terminal (if it hasn't been done before).
If the radiator is being removed to seal a coolant leak, be aware that small leaks can be repaired without removing the radiator from the vehicle using a sealant such as Holts Radweld.
Drain the coolant from the radiator.
For easier access, remove the air filter intake pipe, disconnect the high-voltage wire from the ignition coil and take it to the side.
Disconnect the connectors from the thermal switch and the radiator fan motor.
Pic. 5.3. Radiator: 1 – the top hose of a radiator; 2 - lower radiator hose; 3 - radiator; 4 - radiator fan casing
Disconnect the coolant supply hoses from the radiator and the hose from the expansion tank (pic. 5.3).
Turn away bolts of fastening of a radiator and bolts of fastening of collars, then lift a radiator up. On models with automatic transmission, the radiator must be lifted up to provide access to the coolant lines, disconnected and closed with plugs. Remove the radiator from the engine compartment.
Carefully inspect it, check visually for leaks and damage. If repair is necessary, it is recommended to take the radiator to a specialized workshop.
Remove insects and leaves from the radiator fins with a brush, check and, if necessary, replace all worn hoses and clamps.
The radiator should be flushed as described in sec. 2.
Replace the radiator cap with a new one with exactly the same specifications. If the plug has been recently replaced, then take it to a car service for inspection.
When installing a new radiator, use all connections from the old unit.
Installation is carried out in the reverse order of removal, taking into account the following.
Make sure the heatsink is seated correctly at the mounting points.
After installing the radiator, fill the cooling system with antifreeze of the appropriate concentration, then start the engine and check for leaks.
On models with automatic transmission, check the fluid level and top up if necessary.
