Parts for your 2000 Mitsubishi Pajero-Ignition coils

2000 Mitsubishi Pajero ignition coils: what they are, and when to sort them out

Technical references make it clear that ignition coils are fitted to 2000 Mitsubishi Pajero petrol models, but not to the diesel variants. The Mitsubishi factory service manuals for the NM/NP Pajero (Engine Electrical/Igntion System groups) describe coil-on-plug and coil pack systems on the 6G7-series V6 petrol engines, while noting that the 4M40/4M41 diesels use compression ignition and therefore have no ignition coils. Mitsubishi ASA/CAPS parts catalogues list ignition coil assemblies for the 6G7x petrol engines of this year, with none for the 4M4x diesels. Independent workshop guides such as Gregory’s and Haynes echo the same distinction.

For petrol 2000 Pajero owners, the ignition coils are the unsung heroes under the bonnet. Their job is to step up the 12 volts from the battery to the tens of thousands of volts needed to jump the spark plug gap, so each cylinder fires cleanly. Depending on the exact engine code, your Pajero runs either coil-on-plug (one small coil at each plug) or a paired coil pack with leads to the plugs. Either way, the ECU times each spark and relies on healthy coils to keep the V6 smooth, efficient, and happy towing or touring.

There’s no fixed replacement interval for coils, but they do age with heat and vibration. A sensible plan is to have them inspected whenever plugs are changed (typically 60,000–100,000 km depending on plug type) or at major services. Under Australian and New Zealand conditions—dust, heat, corrugations—regular checks pay off. Look for cracks in housings, swollen or carbon-tracked boots, oil in the plug wells from rocker cover leaks, and any green/white corrosion on connectors. On coil-pack versions, inspect the leads for brittleness and arcing marks.

If a coil fails you’ll usually feel a misfire, rough idle, flat spots, higher fuel use, and a flashing or steady check-engine light with codes like P030x/P035x. Don’t keep driving on a dead coil, raw fuel can damage the catalytic converter. Replace the failed unit and, if the vehicle has many kilometres or multiple coils look tired, consider doing them as a bank or set. Always disconnect the battery, use dielectric grease on boots, torque hold-downs correctly, and route leads exactly as per the service manual to avoid crossfire.

• Common symptoms of a dodgy coil: hard starting, stumble under load, poor economy, sulphur smell from the exhaust, and visible arcing at night.

Quality OEM-equivalent coils and fresh plugs keep the 6G7 V6 crisp. A little preventative attention now saves headaches out bush later.

Does my 2000 Pajero have ignition coils?

Yes for petrol models (6G72/6G74 V6). They use either coil-on-plug or a coil pack, depending on the exact engine. Diesel models (4M40 2.8 and 4M41 3.2) don’t use ignition coils at all because they ignite fuel by compression rather than a spark.

How often should I replace Pajero ignition coils?

There’s no set kilometre interval. Coils are replaced when testing or symptoms show they’re weak or failing. Have them inspected at major services or whenever you do spark plugs. Many last well past 150,000 km, but heat, oil contamination and vibration can shorten life.

Can I drive with a failing ignition coil?

It’ll usually run, but it’s not wise. Misfires can overheat and damage the catalytic converter and oxygen sensors, and you’ll burn more fuel. Sort the coil promptly and check the spark plug and boot on that cylinder at the same time.
