SOURCE: change the spark plug for 1999 pontiac montana

Ok, based on the firing order from your vehicle there are (6) cylinders, and (3) are on the front of the engine and (3) are on the back. I have never even looked under the hood of one of these types of vehicles, however, You MAY need to remove the large plastic engine covering (not sure for your vehicle). If that is the case you may have to remove the engine oil (tube). The cap that you open up to add oil, twist and pull on the actual tube and it should twist off (if needed on this vehicle). Once this is removed if requiered on your vehicle, you can then remove the large plastic covering to have access to each cylinder. Once the large plastic covering is removed, put the oil fill tube back in place for the moment so no contamination gets in your engine. I would start with the back side first because that is hardest. I checked on Autozone.com and they have it listed for this vehicle that the iginition coil is set up on the left side. You should see six wires coming from this area with (3) going to the front and (3) going to the back of the engine. Start on the back side with the whichever of these wires/cables goes to the left side of the back of the engine. Please only do one at a time to avoid confusion as to the placement. What I would do in all honesty if you are doing the tune-up is to replace the spark plug wires as well. What I have used on all of my vehicles and have had great success is NGK plugs and NAPA auto parts has plug wires Belden Maxx (this is only a suggestion and I am only sharing what has worked well for ME). OK, prior to starting what you will want to do is take each individual plug one at a time, and using a spark plug gap tool (readily available at all parts places) Place the non-porcelin end (the one that has the arc in it) into the gap tool at the lowest end and slide it around until you have reached the required gap. For this vehicle it is .60 Even if they tell you at the factory it is pre-gapped and you don't have to check it, believe me it is always a good idea. I just did a vehicle and all (6) were not gapped correctly. Put each one back in the box until needed. Once you have done this,starting on the back of the engine left side find the spark plug cable/wire that goes to that side and where it goes into the engine it will have an end with a boot on it. This covers the spark plug. Twist this boot off the spark plug, it may take some effort. Once that is off if you are replacing the spark plug wires take this one and match it up with the new set (They will be different lengths). Now for the fun part, removing the plug. Using a spark plug socket (available at parts places, has rubber on the inside to grip, and protect the socket) a small extention and your ratchet, place this over the plug and apply pressure until the plug begins to turn. Once you have the old plug out, place the new plug in the spark socket and thread it in by hand (it will be in the socket but don't use the ratchet yet. Once you have the plug in as far as you can by hand tighten it down with the ratchet (don't overtighten). Place the new or old spark plug wire (boot) over the new plug and move on to the next cylinder. Do each one the same way (ONE AT A TIME, to avoid confusion). This is a long explanation but I hope it will help someone...Thanks

remove the ignition coil pack ( 2 10mm bolts on front of it and 2 13 mm nuts on the back side) u will need a long extension and deep socket for the back ones , and unplug all electrical connectors and remove it from the vehicle and you should be able to reach the back plugs without a problem.

Okay, this is a fun job, the front plugs are easy, the back plugs are a littlle more challenging, I ran my van up on ramps, then slid under and you can reach the rear plugs from underneath, by reaching up beside the exhaust pipe. You have the do it by feel. Good luck

2000 Pontiac Montana not starting


Disconnect one of the battery cables for 5 min. Reattach it and tighten manually. This resets the ECM and possibly will allow starting. Disconnect a plug wire and get someone into the drivers seat and attempt to start. Hold plug wire close to spark plug and see if there's a spark. If no spark, either the battery is bad or COIL.

How do you Replace the Spark Plugs on a 1999 Pontiac Montana


The three front ones are simple and the three back ones are challenging. There are two ways to replacing the rear spark plugs on the Montana.
1. If your arms are long enough and you have longs extensions with a spark plug socket with a swivel build in to it, you can get to the plugs from under the Montana.
2. You can get to the rear plugs buy disconnecting the two dog bone engine mounts in front of the engine and tilting the engine forward. You can do this by placing the parking brakes on and disconnecting the dog bone, once that is done. Place your foot on the brakes and take the parking brakes off and push the Montana forward till the engine tilts forward enough to give you the room you need to get your arms over the top of the engine with the extensions and spark plug socket. Make sure you place the parking brakes back on and put a block at the rear of the engine to ensure the Montana will not move back and cause you to loose your arm or head.
Note that you need to keep the transmission in park when tilting the engine and that your going to have to replace the spark plug wires and do everything by touch to replace the rear spark plugs.
Thank you for using Fixya and use platinum spark plugs to give you 100,000 miles of service. Good luck and be safe.
