This article covers checking and adjusting the ignition timing on NF, NG, NH and NJ model Pajero’s fitted with the 3.0 V6 engine.
Before checking or making any adjustments to the timing the Timing Check Connector must be earthed. A length of electrical wire with small alligator clips on each end is handy for this, attach one end to the battery negative terminal or a clean and paint-free metal part of the body or engine and clip the other end to the check connector.
On the NF and NG models the connector is located in the wiring loom near the brake master cylinder. See pic below.
On the NH and NJ models, the connector is located in the wiring loom on the firewall on the passengers side of the vehicle and is the round connector (the fuel pump test connector is located here also and is the rectangular connector) See pic below.
With the timing check connector earthed the timing light can be connected – cylinder number one is the front cylinder on the right hand side (drivers side) of the engine.
Now the engine can be started and the timing light aimed at the harmonic balancer and timing marks. The timing setting for all of the 3.0 V6’s is 5° ± 2°. If the timing marks are difficult to see with the timing light a dab of white correction fluid in the correct place can help.
To adjust the timing loosen the nut securing the distributor and rotate the distributor in small incriments until the mark on the harmonic balancer lines up with the 5° mark on the timing belt cover.
Don’t forget to then tighten the distributor nut! It is also a good idea to recheck the timing in case the distributor moved while the nut was being tightened.
If all is good switch the engine off, remove the earthing wire and go for a test drive. All done!
