❓ Quick FAQ
How do glow plugs differ from spark plugs?
Diesel engines rely on compression and heat, not spark, for ignition. The ZD-11 acts as a heating element, reaching over 1000°C to pre-heat the cold combustion chamber before startup, then cycles off once the engine runs on compression alone.
Why use OEM over cheap aftermarket plugs?
Aftermarket plugs are prone to "tip swelling" from substandard heating coils — when removed, the swollen tip can snap off inside the cylinder, often requiring a full cylinder head removal to extract. Genuine Motorcraft plugs are regulated by the factory Glow Plug Control Module to prevent this failure.
How do I replace these on a 7.3L Powerstroke?
- Disconnect the battery, remove the valve covers, and clean the seam lines before lifting them off.
- Disconnect the wiring harness bullet connectors from each glow plug, checking for heat damage.
- Remove the old plugs with a deep 10mm socket, keeping the socket aligned to avoid snapping the ceramic core.
- Hand-thread the new plugs in (no anti-seize) and torque to 124 in-lbs (10 lb-ft).
- Reconnect the wiring harness, reinstall the valve covers, and torque bolts to 98 in-lbs.
- Reassemble components, reconnect the battery, and verify a clean cold start.
