How often to change spark plug wires on a 2003 Ford Explorer?
After 15 years they're due.
Spark plug wires are found on vehicles that have distributor caps. Yours has ignition coils so there are no spark plug wires per se. There are a couple of wiring harnesses though but they should not need replacing the way spark plug wires do.
It is a coil on plug ignition design. There are no "wires".
When they are needed
You change them when they fail. They don't graduate and some may last longer than the car. If it ain't broke don't fix it.
On modern cars no plug wires, don't rotate tires, use synthetic oil, change oil every 10k, it's not the 50s any more
There's no wires. They are coil packs. Change them as they go bad and do spark plugs every 100k
60,000 miles
Just change them when they are needed bud. One goes bad replace them all as a set. And yes they are still considered spark plug wires even if it has a coil pack. I have used wires from a car that had a distributor on one that has a coil pack and worked just fine. But whenever they are needed. Say one goes bad might as well replace all of them and I usually replace them and the spark plugs together. Hope this helps.
Every 3 years
- Why is my car running rough with new spark plugs and wires? I have a 2003 Ford Taurus SE and it was running rough, so I put in new spark plugs and wires and it is still running rough. I was wondering what is wrong with my car.
- Would bad spark plug wires cause a check engine light? I just changed the valve cover gasket on my car. Then when I tried to start it, it started violently shaking and the check engine light turned on. The only thing I could think is that maybe the spark plug wires broke when I took them off. Would that cause a check engine light? It's a 2002 Ford Focus ZTS with 150000 miles
- F150 Ford, rain and humidity prevents starting. It's not the distributor or plug wires? It's not the distributor or the wires. Fuel pump is pumping? If it's already running when it's raining, it will continue to run just fine. It's definitely condensation somewhere?
- On 2002 ford explorer 4.6l the spark plug is drowning in fluid? Happen before on rear cylinder #4 w/ antifreeze from crack in upper intake manifold drowning out the spark plug. So I replaced it, now #2 is doing it, but it seems more like water than antifreeze. It does seem to happen when wet or rainy out. Could it be possible to get that much water up to the top of the engine to settle around my worn out seal for a spark plug boot?
