31. Unscrew bolts and remove the top suspension brackets of a radiator, then take a radiator from the lower rubber support up.

Check

PERFORMANCE ORDER
1. If the radiator was removed in connection with reduction of capacity, wash out its stream waters in two directions. Outside blow a radiator compressed air.
2. If the radiator proceeds, do not try to make or solder the place of a leakage since plastic details of a radiator will be damaged.
3. Insignificant leakage of a radiator can be eliminated with radiator sealant use.
4. Check a condition of the lower rubber support of a radiator and if necessary replace them.

Installation

PERFORMANCE ORDER
Installation is made in the sequence, the return to removal taking into account the next moments:

 – check that the lower ledges on a radiator were established in rubber support;
 – check that all hoses are correctly connected and reliably fixed by collars;
 – in conclusion fill in cooling liquid in the cooling system.
