Location of the coolant drain plug on the cylinder block.
If you remove the fan together with the radiator, then operations 6 and 9 do not need to be performed.
One possible reason for engine overheating may be a clogged radiator. In this case, flush the radiator with water.
Check the radiator for leaks. To check, plug the radiator pipes, supply air to it under a pressure of 0.2 MPa (2 kgf/cm²) and lower the radiator into a bath of water for 1 min. If air bubbles appear, the radiator is not leaky and must be replaced.
