The 572.44901 is a 1.5-inch oil filler cap designed for heavy-duty diesel engines.
Confirm the part fits before you buy. Applications and interchange numbers are researched and audited per part.
We don't publish fitment for this part yet. Rather than guess, get it confirmed against your truck in under a minute.
It seals the oil fill port on the engine to prevent dirt and debris from entering the crankcase, and it also stops oil from splashing out. Replace your original cap when it becomes cracked, lost, or no longer seals tightly to maintain proper engine lubrication. This cap is a common replacement for many commercial trucks and off-road equipment that use a 1.5-inch filler neck opening.
