The key to trouble-free engine operation lies in the cleanliness of the radiators and the condition of the water pump. Overheating causes plastic connectors to burst, resulting in leaks of lubricant and antifreeze. The use of cheap oils leads to rapid wear of the camshaft bearings. We do not recommend installing gas equipment, as it will simply cause valve seat failure. Ignition coils, fuel pumps, and adsorbers are also considered weak points of the assembly.
