FAQ

Q: How do I confirm if this glow plug fits my excavator’s Isuzu engine?
A: Verify your engine model (e.g., 4HK1, 4HL1) by checking the engine data plate. Then, locate your current glow plug’s part number. If it matches 8-94390777-6 or 8943907776, this is the correct replacement. If you have a different number, please contact us with your engine serial number and part number for cross-reference verification.

Q: What are the signs that my glow plug needs replacement?
A: Common symptoms include difficulty starting the engine, especially in cold weather, excessive white smoke during start-up, a rough idle until the engine warms up, or a check engine light related to the glow plug circuit. Visually, a blown fuse in the glow plug relay circuit can also indicate a faulty plug drawing excessive current.

Q: Can I replace just one glow plug, or should I replace all of them?
A: While it is technically possible to replace just one faulty glow plug, it is highly recommended to replace all glow plugs in the engine at the same time. This ensures uniform heating performance and prevents future failures of older plugs. Uneven heating can lead to cylinder imbalance and rough starting. Always replace the glow plug relay if it shows signs of wear.
