The 202V08601-6001 Intake Air Preheater Assembly is a critical component for the Sinotruk engine family, specifically engineered for the HOWO, Sitrak (Shandeka), and Hohan series.
This preheater works by rapidly warming the intake air before it enters the combustion chamber, significantly reducing cranking time and protecting your starter motor and batteries from excessive wear during winter. Manufactured to original factory standards, it ensures perfect synchronization with the engine’s ECU, providing the exact heat intensity required for a clean ignition without wasting energy.

A faulty intake heater can lead to white smoke or complete start failure in cold weather. Follow these professional tips for replacing the 202V08601-6001:
Safety First: Always disconnect the vehicle’s main battery master switch before beginning. The preheater carries high current, and accidental grounding can cause severe sparking.
Terminal Integrity: Inspect the heavy-gauge electrical cables for signs of melting or corrosion. When installing the new heater, ensure the copper terminals are cleaned and tightened to the specified torque. Loose connections are the #1 cause of heater failure.
Gasket Replacement: Always use a new gasket between the intake manifold and the preheater. An air leak at this junction will bypass the air filter and cause turbocharger or engine wear.
Relay Testing: If the new heater does not seem to activate, check the preheater relay and the 80A/100A fuse. Often, a failed heater will blow the fuse during its final moments of life.
ECU Synchronization: After installation, clear any old "Cold Start Performance" fault codes using a diagnostic tool to allow the engine control module to reset its heating cycle logic.
