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.
