Replacing spark plugs

What is the best way to access spark plugs and replace them (pass side) in a 98 explorer 4.0 sohc engine? Thanks.

On my '92 OHV, I access #3 (and sometimes #2) by going from the side through the wheel well. I think the SOHC can be done the same way.

Yep, thru the wheel well. Also, remember to put anti-seize on the new plugs. You should also consider doing the wires since they are such a pita to get to.

Make sure you replace them with OEM grand plugs and wires, Autolite or Motorcraft only. Otherwise you may find yourself doing the job again and/or having low power, pinging and detonation, and other problems.

Is this engine known for breaking the plugs off in the head when removing them ?

Not if you take your time and get a straight shot on them. Hopefully, whoever did them the last time used anti-seize. Some people make the mistake of putting WD40 on new plug threads. Not a good thing to do. When the engine heats up, it bakes the Wd40 into the threads thus creating a bond between the plug and the head.
