how to change front and rear spark plugs on a ford 500
The front three are in the center of the valve cover under the three round coils. The rear three are in the same place on the backside of the engine but the upper intake manifold must be removed to access them.
This is true. You have to remove the manifold, lots of wires and hoses, and the brace that goes across the top of the firewall. You need a 24MM socket to remove the brace. It is the easiest part of the job. Takes lots of time. Good luck. Shame on the man who designed this!
The front three took less than 15 minutes for change. I pissed around trying to take off that manifold for an hour before deciding doing it myself could very easily end up being pound foolish decision. I put it all back together and booked an appointment at the garage.
It took the mechanic nine hours to replace the plugs mainly because of the horrible design having to disassemble everything to get to the rear three plugs. Then I had to buy new seals for another$40.
I just changed all 6 spark plugs, pcv valve, air filter, cleaned the throttle body and changed the fuel filter on my fiancé car. I know basic mechanic skills but I never worked on a ford before so it was a little bit different. Took me about 5 or 6 hours in the driveway but I was in no rush. I found helpful video or two on utube, the hardest part was finding what fuse it was going to the fuel pump to depressurize the fuel line(F27 under the hood). Just take your time and when you take a hose or clip off the intake just remember where it goes or take a pic with your phone. Factory plugs are Motorcraft and I always check the gap before I put plugs in, don't trust pre gapped plugs.
