This is an 8-rib engine drive belt designed to transmit power from the crankshaft to various engine accessories like the alternator, power steering pump, and air conditioning compressor. It is constructed from durable, heat-resistant rubber compounds to ensure consistent tension and prevent slippage, unlike a worn belt that may crack or fray. Operators may notice a high-pitched squealing noise from the engine bay, especially during startup or acceleration, if this belt begins to fail.
Always verify with serial number before ordering.

Inspect mating surfaces for wear before fitting. Use torque specs from service manual. Replace gaskets and seals as a set — reusing compressed gaskets causes oil leaks. Clean all oil passages with compressed air.
Always consult the OEM service manual for model-specific torque values and procedures. WhatsApp our technical team if you need fitment guidance.
A failing drive belt may initially produce a high-pitched squealing sound, particularly noticeable on startup or under load. If ignored, the belt can start to fray, crack, or lose tension, leading to intermittent or complete loss of function for accessories like the alternator or cooling fan. Continued operation with a compromised belt risks overheating or loss of critical system functions.
Ensure the pulley grooves are clean and free of debris before installation to prevent premature belt wear. Never use excessive force or pry tools against the belt's sidewall when fitting it onto the pulleys.
Inspect the belt tensioner and idler pulleys for proper function and wear during drive belt replacement.
