Description
Genuine ACDelco 55493234 Oil Pump Belt for the 3.0L Duramax Diesel (LM2 & LZ0). This wet belt is responsible for driving the engine’s oil pump — a critical component for proper lubrication and long-term engine health.
Unlike traditional drive belts, this belt is submerged in engine oil and located at the rear of the engine, requiring transmission removal for service. Despite widespread concern, there have been zero known failures in over 5 years of real-world use.
