Replace spark plugs in 1997 4 cyl. ford ranger
I will suggest you get these few tools before you with the replacement.
(1) Spark plug socket with rubber insert to hold plugs in place while inserting & removing.(2) 6inch extensions for your 3/8ths inch socket wrench,(1) Swivle Socket extension for your 3/8ths inch socket wrench.(1) 1/2inch socket for exhaust manifold screws.
A little quantity of anti-sieze for the spark pluggs to be applied to the pluggs if they are proving difficult to get out.
Start with the 1st cylinder at the front of the engine on the passanger side.
Twist & remove the spark plug boot from the existing plug.
You have to use a very small flat edged screwdriver to open the clips that hold the plug wires together.
Use a 6" extension & a 3" extension & your deep socket for the spark plug.
Remove the first plug and replace the old plug with a new Bosch Platinum Plus 2 prong plug and use some anti-seize on the threads and tighten to the appropriate torque.
Remove the old plug wire from the coil pack. It will be going to the 2nd coil pack (located to the rear of the first coil pack) and install the new plug wire in the coil pack.
Repeat steps 1-7 for plugs on 2 & 3.
To remove Plug #4 which is the last plug on the passanger side,you have to remove the two (2) 1/2inch bolts that holds a bracket to the exhaust manifold. Make sure you spray the studs these bolts are on with some DW-40 or liquid wrench. The exhaust manifold studs might have a lot of rust & being difficult to turn nuts off without shearing off the stud. It has some sort of aluminum box ontop of this bracket with some sensor wires coming out of it, Slip the bracket off and simply lay it to the rear of the engine to provide better access to this last cylinder.
Repeat steps 1-7 for plug #4 and then Remount bracket containing the aluminum box with sensor wires.
Upon completion of the passenger side,you now have to proceed to the driver side.
The first cylinder at the front of the engine the spark plug wire has a grey handle sticking up next to the A/C compressor. Using some pliers (needle nose plier) twist & pull this grey handle. The spark plug boot should pop out.
STEP 2.With the help of the small flat edged screw driver, unhook the spark plug wire clips that hold the wires together. There are 3 - One just after the 1st coil pack located at the front of the engine, another just on the other side of the valve cover and a small 2 clip located about 1/2 way back on the valve cover under the intake manifold.
STEP 3.Remove the spark plug wire from Cylinder #1 on the Drivers side
STEP 4.With the help of the small flat edged screw driver,press the 4 connection points on the grey handle that is attached to the wire,it will separate down the middle and allow you to remove the wire,
Replace the wire with the new wire,you have to ensure you line up the rubber round plugs with the round holes in this grey handle & snap it back together with the new wire in place.
STEP 5.Hold the spark plug socket in your left hand down near the plug,feed a 6" inch extension below the A/C Compressor line (black pipe) and the A/C Compressor with your right hand and attach the spark plug socket into the extension.
STEP 6.Slip the socket onto the plug,afterwards,attach an additional 3 or 6 inch extension to the existing extension & attach your socket wrench.
STEP 7.Remove the plug & proceed to replace it with a Bosch Platinum plug & anti-seize on the threads. Feed the new Spark Plug wire over to the 1st coil pack & replace it on the coil pack.
