Attention! If the plugs of the cooling system channels fall into the channel of the cylinder block, then it is usually impossible to remove them.
1. Drill holes in the plugs and pull out by screwing bolts or self-tapping screws, or remove with a bent-legged puller.
2. Carefully clean the block of seal residues (photo).

3. Remove covers of radical bearings and get bearings from the block of cylinders and covers. Mark all the details so as not to confuse them.
4. Clean all channels with steam jet and compressed air (it is recommended to perform in a car service), wash the outside of the unit with detergent. Drive all threaded holes, clean and blow with compressed air (photo). Dry the block and grease the machined surfaces with spindle oil.
