🔌 Function

This scheduled-maintenance kit groups the cooling, ignition, fuel, lubrication and corrosion-control components required for the listed engine family. Replacing the matched consumables together helps restore reliable starting, correct cooling-water flow, clean fuel and oil circulation, and leak-free drain and thermostat joints.

Common signs that service is due:

• The annual, 100-hour or manufacturer-specified service interval is due

• The engine's previous service history is unknown

• Cooling-water flow is weak or the engine runs hotter than normal

• Spark plugs are fouled, filters are restricted or starting quality has deteriorated

• Drain seals, pump components or sacrificial anodes show corrosion, wear or leakage

📦 Condition

• New aftermarket replacement service kit

• Brand new

• Supplied in original or equivalent packaging
