You must remove the aluminum Intake manifold ( upper & middle portion only ) to access the spark plugs. It's best left to a Professional Mechanic to do the job. The cost can vary. Look at atleast $400.00.. Just as a side note. The biggest hassle will be putting all those hoses & wire plugs you disconnected back in the right spot. The other is locating the proper bolts ( under all those hose & wires ) to remove the intake. Remember that this intake manifold only breathes air so no antifreeze BS to worry about. If you have the proper tools, patients & alot of time you can do it. I suggest perhaps taking some digital photos of the engine before you dig in - it will assist in getting some hoses back to the right spot ( label or color code hoses & wires first ) Good Luck ! And I will be doing this this weekend!

Just like the 1998 model !!! Really ... Have Fun it's MitsushiTTI

This is also a good time to go ahead and check if you need to replace your water pump since you will already have everything off you need to get to it, save your self on some labor cost if you are paying someone to do this, or just save yourself the headache so you dont have too take all that crap off again if your h2o pump goes out.

How do you get to the spark plugs on a Mitsubishi Montero?

We have a 1995 Mitsubishi Montero (the people that brought your the fighter ZERO) and when it came time for a tune-up we couldn't get the plugs out. The car dealer here charged us over 500 dollars for a tune up and they had to remove the top part of the engine to reach the plugs, hence the large dollar value.

How do you replace the spark plug wires on a 2002 Mitsubishi montero limited?

first of all you have to consider several things. 1. what is the mileage? if you have high miles you will want to change the valve cover gaskets. The reason is you will need to remove the plenum to get to the plugs and you will want to do this right the first time. 2. change your plugs while you are in there. This is very easy to do. It looks intimidating but invest the time and you be surprised how easy it is. I just did the timing belt, guide, tensioner, hydraulic tensioner, water pump, valve cover gaskets, plugs and plug wires and fuel filter and my montero runs like new with 140,000 miles.

Will a 93 dodge stealth 3.0 fit in a 89 Mitsubishi montero?

Although the 93 Dodge Stealth basic engine mechanicals are the same as one for a Montero, you would probably have to use different engine mounts and there may be a problem with how the engine mounts to the transmission. Then theres the possible problem of the engine computer for the Montero not working with the donor engine and the wiring harnesses not having the same plugs as the Stealth.

2 hours if your top notch technician. You have to remove the upper intake manifold before you get to them. And about 6 hours if you are not a top notch technician. Just remember to mark everything with a paint pen or marker of so sort, even take photos to try and help with putting the manifold back together.
