Parts for your 2019 Haval H6-Ignition leads

2019 Haval H6 ignition-leads: what’s fitted and what to service

For the 2019 Haval H6, traditional ignition leads (high-tension spark plug wires) aren’t used. This model runs a coil-on-plug (COP) ignition setup, where an individual ignition coil sits directly on top of each spark plug. There are no separate leads running from a distributor or coil pack to the plugs.

This isn’t guesswork. Technical sources for the H6—namely the GWM/Haval H6 Workshop Manual (Ignition System description for the GW4G15/GW4C20-series engines), the GWM Global Electronic Parts Catalogue (EPC) for 2017–2020 H6 models, and the 2019 H6 Owner’s Manual maintenance sections—identify “ignition coil assemblies” and spark plugs, but do not list high-tension ignition leads as service parts. The ignition system overview in the workshop documentation specifies direct-mounted coils, confirming there’s no role for traditional leads on this vehicle.

Why did Haval drop ignition leads? COP brings stronger, more precisely timed spark right at the plug, better reliability, less electrical interference, tidier packaging under the bonnet, and improved diagnostics. It’s a common design across modern turbocharged, direct-injection four-cylinder engines like the H6’s 1.5T and 2.0T units.

What should owners service instead? Focus on:

• Spark plugs: Replace at the interval in the owner’s manual (often 60,000–100,000 kilometres for iridium plugs, but check the H6 schedule). Use the correct heat range and gap, and torque to spec.
• Ignition coils and boots: Inspect for cracking, carbon tracking, oil intrusion from the plug tubes, or moisture. Replace individual coils if there’s a misfire, rough idle or check-engine light with a coil-related fault code.
• Seating and sealing: Ensure boots are clean, lightly treated with dielectric grease, and fully seated on the plugs to prevent arcing.

Typical symptoms of ignition trouble on a COP H6 include misfires under load, sluggish performance, poor fuel economy and an illuminated MIL. Because there are no ignition leads to replace, coils are serviced on condition, while plugs follow the standard service schedule. Sticking with genuine or high-quality aftermarket parts and keeping water and solvents away from the coil tops during cleaning will help the H6 run sweet for the long haul.

Popular questions about 2019 Haval H6 ignition-leads

Does the 2019 Haval H6 have ignition leads?
It doesn’t. The 2019 H6 uses a coil-on-plug ignition system with one coil per cylinder mounted directly on the spark plug, so there are no traditional high-tension leads to service or replace. The correct service items in this area are the spark plugs and, if required, the individual ignition coils and their boots.

What should be serviced instead of ignition leads on a 2019 H6?
Follow the spark plug replacement interval in the owner’s manual and inspect each ignition coil and boot for damage, tracking or oil contamination. If a misfire fault code points to a specific cylinder, swap or replace that coil. Keeping the boots clean and using a dab of dielectric grease helps prevent future arcing.

How often should the spark plugs be replaced on a 2019 H6?
The exact interval is in the Haval service schedule for the engine variant. Many turbocharged engines on iridium plugs sit around 60,000–100,000 kilometres. If performance dips, fuel economy worsens or there are misfire codes, bring replacement forward and check the coils at the same time.
