Overview
The Crown Automotive 33001016 is a black plastic oil filler cap for 2.5L 4 cylinder and 258 6 cylinder engines.
Crown Automotive has been making Jeep replacement parts for a long time, and its catalog includes factory-discontinued items. This cap is universal fit, so it is not tied to a year, make or model.
Key features
- Black plastic oil filler cap
- Fits the 2.5L 4 cylinder engine
- Fits the 258 6 cylinder engine
- Universal fit with no specific vehicle named
Engine size and cap swaps
A filler cap is a small part, but it closes the oil system to the outside air. When an engine is rebuilt or the valve cover is replaced, the old cap often comes off in pieces or no longer seals. Replacing it at the same time is a low-cost way to avoid leaks and dust at the oil fill.
Because engine size matters more than the vehicle model for this cap, compare the old cap’s engine size with the fill neck before buying. Some oil fill openings differ between engines, so a cap that fits one may not sit correctly on another. A cap that rocks or pops off once installed should be swapped before the engine is run hard.
- Compare the old cap’s markings with the new one
- Replace a cap that cracks or loses its seal
- Clean the fill neck before fitting the new cap
