M2C00-3705061 Ignition Coil for YUCHAI YC6MK YC6L YC6G Natural Gas Engine | RJT PARTS
Product Overview
The M2C00-3705061 ignition coil delivers high-voltage spark to the cylinders in Yuchai natural gas engines. It steps up 12V or 24V battery current into the thousands of volts needed to fire the spark plugs cleanly and consistently. This part fits a wide range of Yuchai CNG and LNG engines that power buses, trucks, and generators across the Middle East, Southeast Asia, and Africa.
RJT PARTS supplies the M2C00-3705061 coil as a direct-fit aftermarket replacement. It matches the original Yuchai mounting footprint and electrical connector, so installation takes minutes on the cylinder head. Every coil passes bench testing for insulation resistance and spark output before we ship it.
Yuchai natural gas engines hold a dominant position in overseas bus markets. For example, over 10,000 Yuchai-powered buses serve the annual Hajj pilgrimage in Saudi Arabia alone. Therefore, demand for reliable ignition coils stays high year-round.
Cross-Reference Yuchai Part Numbers
Yuchai uses a prefix-based numbering system for ignition coils. The prefix identifies the engine platform, while the suffix (3705061) remains consistent across most gas engine families. All numbers below interchange physically with M2C00-3705061.
| Yuchai Part Number | Engine Platform | Common Application |
|---|---|---|
| M2C00-3705061 | Universal / Multi-platform | Buses, trucks, generators |
| M2D00-3705061 | Dongfeng Tianjin / JAC | Medium trucks |
| K1A00-3705061A | YC6L, YC4G | Buses, heavy trucks |
| FN100-3705061A | YC6G, YC6MK | City buses, coaches |
| G2K00-3705061A | Yuchai / Weichai gas | Multi-brand application |
| MKA00-3705060C | YC6MK (10L) | Heavy buses, trucks |
| SN1000-3705061 | Universal (Torch brand) | Aftermarket replacement |
| TVN100-3705061 | Gas generator sets | Stationary power |
| AN1000-3705061 | Universal | Multi-application |
Important: The suffix 3705061 is the core identifier. If your old coil shows any prefix before this suffix, it belongs to the same interchange family. When in doubt, send us a photo of the old coil or your engine nameplate.

Key Features
- Broad platform coverage. One coil fits most Yuchai natural gas engines from 4L to 10L.
- Dual voltage support. Works with both 12V and 24V electrical systems found in buses and trucks.
- Heat-resistant housing. Epoxy-sealed construction withstands high under-hood temperatures in desert climates.
- Direct fit. Matches OEM connector and mounting bolt pattern — no wiring modifications.
- Cost-effective. OEM-level performance at a lower aftermarket price point.
Failure Symptoms — When to Replace
- Engine misfire under load or at highway speed
- Check engine light with misfire codes (P0300–P0306)
- Increased gas consumption (higher CNG/LNG usage)
- Rough idle or hesitation on acceleration
- Loss of power, especially on gradients or with full loads
- Visible cracks, carbon tracking, or burn marks on the coil body
- Hard starting in cold weather
Fleet tip: On high-mileage Yuchai gas buses, replace all coils during a major tune-up. Mixed-age coils cause uneven combustion and shorten the service life of newer units. RJT PARTS offers discounted 4-coil and 6-coil engine sets.
Installation Notes
- Disconnect the battery before starting work.
- Remove the engine cover and any intake piping blocking the coil pack.
- Unplug the electrical connector from the faulty M2C00-3705061 coil.
- Remove the hold-down bolt and pull the coil straight off the spark plug.
- Compare the old coil with the new unit to confirm matching dimensions and connector orientation.
- Apply dielectric grease to the inside of the new coil boot before installation.
- Seat the new coil and torque the mounting bolt to Yuchai factory specification.
- Reconnect the harness and battery. Clear fault codes and start the engine to verify smooth operation.
Follow Yuchai service manual lockout/tagout procedures for natural gas fuel systems before servicing.

FAQ
Q: What does the prefix in M2C00-3705061 mean?
A: The prefix (M2C00) identifies the Yuchai engine platform. The suffix (3705061) is the standard ignition coil identifier. Most Yuchai gas engines use coils with different prefixes but the same 3705061 suffix — they interchange physically.
Q: Will this coil fit a Yuchai diesel engine?
A: No. The M2C00-3705061 fits natural gas (CNG/LNG) engines only. Diesel engines use compression ignition and do not require ignition coils.
Q: How many coils does a YC6MK engine need?
A: The YC6MK is a 6-cylinder engine, so it uses 6 ignition coils — one per cylinder. YC4G and YC4E 4-cylinder engines use 4 coils.
Q: Can I use K1A00-3705061A instead of M2C00-3705061?
A: Yes. Both numbers belong to the same interchange family. They share the same dimensions, connector, and electrical characteristics.
Q: What is the warranty?
A: 12 months from the date of delivery. We replace any coil that fails due to manufacturing defects.
Q: Do you ship to my country?
A: Yes. We ship worldwide, including the Middle East (Saudi Arabia, UAE), Southeast Asia (Vietnam, Thailand, Indonesia), Africa (Nigeria, South Africa, Kenya), and South America.
