FAQ

Q1: How do I verify that this glow plug fits my Yanmar 4D84/4D88 engine?
A: Check your existing glow plug for three critical measurements: (1) thread diameter (typically M8 or M10), (2) total length from sealing surface to tip, and (3) voltage rating (usually 10.5V or 11V for Yanmar systems). Compare these with the OEM part number listed in our cross-reference section. For absolute certainty, remove one existing glow plug and measure it against our specifications.

Q2: What is the correct installation procedure for this glow plug?
A: Installation should be performed on a cool engine. Clean the glow plug hole threads with a tap to remove carbon deposits. Apply a small amount of anti-seize compound to the threads (avoiding the heating tip). Torque to manufacturer specification (typically 15-20 Nm for M8 threads). Do not over-tighten, as this can damage the heating element or cylinder head. After installation, test the glow plug circuit for proper voltage before starting the engine.

Q3: How long should a Yanmar diesel glow plug last, and what are signs of failure?
A: Under normal operating conditions, glow plugs typically last 60,000-100,000 miles or 3-5 years. Signs of failure include: (1) hard starting, especially in cold weather, (2) white smoke from exhaust during startup, (3) engine misfiring or rough idle when cold, (4) visible damage to the glow plug tip (swelling, cracking, or melting). We recommend replacing all glow plugs as a set (usually 4 pieces for 4-cylinder engines) to ensure balanced heating performance.
