HOW IT WORKS
The drain plug assembly is essentially a threaded bolt with a seal. It has the important job of keeping the vital lubricant in the oil pan by providing a seal between the drain plug and the drain pan.
WHY IT MATTERS
The plug is a low-cost, reliable way to access the fluid drain. A proper plug prevents issues such as contamination, leakage, and shift problems.
