Can anyone tell me how to remove and install new spark plugs to the 3 rear cylinders on the 3.1 engine. Have replaced the front 3 plugs. Removed the air cleaner and tried reaching over the engine to get to the rear plugs but it appears a very difficult job.

Best done from below on a hoist. Possible to do lying on your back with ramps, but definitely not fun..
thanks for your advice. may leave it until I change exhaust down pipe.
Thanks for your advice. will try this method.
Thanks to everyone who replied. Job has been done by removing alternator (
2nd time in 2 years its broken down) and while alternator was removed I managed to get the rear plugs out with the aid of a mirror / light and plug spanner. Never again!Join the Discussion
