🔧 Product Description

🔌 Function

Groups the principal scheduled-service components needed to maintain reliable ignition, clean fuel and oil circulation, correct cooling-water flow, leak-free drain and thermostat joints, and effective sacrificial-corrosion protection. Replacing the matched consumables together helps reduce repeated disassembly and supports consistent annual or hour-based servicing.

Common signs service is required:

• Annual, 100-hour or manufacturer-specified maintenance interval has been reached

• Previous service history is unknown or incomplete

• Hard starting, misfire, fouled plugs or reduced throttle response

• Restricted fuel flow, contaminated filters or fuel starvation under load

• Weak tell-tale flow, rising engine temperature or an overheat warning

• Cracked, hardened or missing water-pump impeller vanes

• Oil or gear-lubricant seepage from deteriorated drain-plug seals

• Sacrificial anodes are heavily consumed, loose or no longer making clean metal-to-metal contact

📦 Condition

• Brand-new aftermarket service kit

• Supplied as new replacement components

• Supplied in suitable retail or equivalent packaging
