This genuine Nissan O-ring is a crucial seal for the coolant water pipe on the V9X 3.0L V6 turbo diesel engine. The original O-ring is constantly exposed to high temperatures and pressure. This causes the rubber to harden, flatten, and eventually crack, leading to coolant leaks. Ignoring a small weep can result in a significant loss of coolant, causing your engine to overheat and leading to very expensive damage like a warped cylinder head.
