🔌 Function

Provides the principal routine-service components used to maintain correct ignition, fuel delivery, cooling-water flow and fluid sealing. Renewing these items at the proper service interval helps support reliable starting, stable running, normal operating temperature and protection against contaminated oil or water-pump failure.

Common signs service is required:

• Hard starting, misfire, poor idle or reduced throttle response

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

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

• Cracked, hardened or missing impeller vanes

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

• Scheduled annual, 100-hour or storage-return maintenance interval reached
