Maintain reliable cold-start performance with this Genuine Nissan Glow Plug Relay, designed to suit Nissan Patrol GQ and GU models fitted with TD42 and ZD30 diesel engines. This OEM relay is a critical part of the glow plug system, controlling the electrical current supplied to the glow plugs to ensure proper pre-heating of the combustion chambers before engine start.

Over time, glow plug relays can fail due to internal contact wear, heat exposure, and electrical load fatigue. When this happens, it can lead to hard starting, excessive cranking, rough cold starts, or even a no-start condition, especially in colder conditions.

Manufactured to genuine Nissan specifications, this factory replacement relay provides precise electrical control, reliable cold-start operation, and long-lasting durability to help maintain your Patrol’s starting system performance in demanding Australian conditions.
