At the same time, try not to touch it with the middle part of other parts of the machine - you can damage the aluminum fins of the radiator tubes.
If necessary, remove and replace the rubber pads of the radiator.
We install the radiator in the reverse order, then fill in the coolant (see Coolant replacement).
Attention! When installing hoses connecting the elements of the cooling system, replace the standard clamps with worm gears. They seal the joints more reliably and are more convenient for repairs.
Before installing the old radiator, it is recommended to rinse its internal cavity with water through the nozzles, and also wash it from the outside.
You can flush the engine cooling system without disassembling it. There are many drugs designed specifically for this. It is more convenient to use them when changing the coolant. Before using the drug, carefully read the instructions attached to it. As a rule, the cleaner is added to the old coolant through the radiator neck. Then we start the engine and after the expiration of the time specified in the instructions (from several minutes to several hours), drain the coolant. We flush the engine cooling system with water, removing the remnants of the drug and dirt, and then fill the system with fresh coolant.
Attention! Long-term operation of the car with a cleaner in the cooling system (more than the time specified in the instructions) is not allowed.
