Como Cambiar Las Bujías De Ford Exploer 2001

I found out firsthand today why tune-ups are so expensive. On the 1999 Explorer with the 4.0L V6 SOHV, the plugs are a bit of a pain to get to, especially on the passenger's side of the engine. I have a Haynes manual for my vehicle; I found it was vague on what would be involved to change the spark plugs.

In case you're about to undertake the same project, I wanted to offer what I learned from my experience. You'll need the following tools and supplies:

- 1/2" drive breaker bar (optional)

- 1/2" drive, 3/4" socket (optional)

- 3/8" drive ratchets, stubby and standard

- 3/8" drive, 5/8" Spark plug socket

- 3/8" drive universal joint

- 3/8" drive 2" and 6" extensions

- 1/4" drive, 8mm and 9/32" sockets

- 1/4" drive ratchet (or you can use a 3/8"-to-1/4" adapter)

- Phillips screwdriver

- Flat screwdriver

- 5/16" nutdriver

- Spark plug gap gauge

- Floor jack with sufficient capacity to lift your vehicle

- A jack stand

- Anti-seize compound

- Spark plug boot grease

Remove the cover over the intake assembly using the 9/32” socket. Store it out of the way. Pull hose and rigid tube out of the intake breather hose. Remove the wiring harness from the mass airflow sensor. Unclip the breather housing, loosen the 5/16” screw on the intake hose, and move the intake breather hose and housing out of the way.

I suggest starting with the passenger's side first to get the most frustrating part of this project out of the way. Using the flat screwdriver, remove the front passenger's side hub cap. Then using the 1/2" drive breaker bar and 3/4" socket (or your tire iron), loosen the lug nuts. Jack the vehicle up and secure it on a jack stand and finish removing the lug nuts and tire.

Next, remove the wheel well. There are four (4) Phillips screws and four (4) 8mm screws that secure it to the vehicle. There are two (2) 10mm lag bolts at the front of the wheel well - DO NOT remove these yet. One of the Phillips screws will be under the back corner of the wheel well under the running board (if equipped). Pull the wheel well out of the fender. You may notice a vacuumreservoir (black spherical component) with two small vacuum lines; it is secured by the 10mm bolts that you did not remove earlier. Free the lines from the clip securing them to the wheel well, then remove the bolts securing the vacuum reservoir. Gently stow it out of the way.

Look at the engine from the engine bay. On the passenger's side, you'll see the two front spark plug boots quite easily. The third one closest to the firewall is hidden by the air-conditioning evaporator housing. Ease of access to all three of these plugs is primarily the reason why you
