Dodge Oil Pan

Choosing An Engine Oil Pan

Oil pans differ by the engine or transmission they serve, the mounting position and the shape of their sealing surface. An engine oil pan must match the engine's lower assembly and the openings used by that application. Some vehicles have separate upper and lower pan sections, so identify the section being replaced before choosing a part.

How An Engine Oil Pan Supports Lubrication

The engine oil pan collects oil after it drains back from lubricated parts. The oil pump draws from the sump and sends oil through the engine's lubrication passages. The pan is the reservoir; it does not circulate oil on its own.

A sound pan and sealing surface help keep oil inside that system. A crack, corrosion or a damaged drain-plug area can let oil escape.

Oil Pan Shape, Openings And Material

Compare the pan's mounting flange, bolt-hole pattern and sump shape with the engine assembly. The drain-plug thread and the location of any required openings also matter. A similar-looking pan can interfere with the pickup or surrounding components if its shape is wrong for the application.

Steel and aluminum pans are both represented among the available products. Material alone does not make two pans interchangeable. Use the specified part and the sealing method for the engine, including the correct treatment at joints where multiple covers meet.

Engine And Transmission Oil Pans

An engine oil pan holds engine lubricant; an automatic transmission pan belongs to the transmission fluid circuit. They mount to different assemblies and use different fluids and service procedures. An oil-pan search can show both, so confirm the system before comparing dimensions or ordering a seal.

For an upper-and-lower engine design, the lower sump is not necessarily the whole housing. The required repair depends on which section and sealing surface are damaged.
