Removal
1. Drain the fluid from the radiator and cylinder block by removing the drain plugs in the lower radiator tank and on the cylinder block; open the cabin heater tap and remove the radiator cap from the filler neck.
Attention! To avoid damaging the radiator, when unscrewing the drain plug of the lower tank, use a second wrench to support the plug nipple soldered into the radiator. Unscrew the plug with a socket or open-end wrench to avoid damaging the edges of the plug.
2. Disconnect the hoses from the radiator.
3. Loosen the bolts and remove the fan shroud.
4. Remove the radiator from the engine compartment by unscrewing the bolts securing it to the body.
Checking for leaks
1. The radiator tightness is checked in a bath with water. Having plugged the radiator pipes, supply air to it under a pressure of 0.1 MPa (1 kgf/cm³) and lower it into a bath with water for at least 30 s. In this case, no air leakage should be observed.
2. Seal minor damage with soft solder, and if it is significant, replace the radiator with a new one.
3. Jamming is allowed (necessarily on both sides) no more than 1.5% of the radiator cooling tubes.
