How do I change the spark plugs of my Pro Ceed?

Follow these six steps to replace the spark plugs of your Pro Ceed:

⚠️ Before you begin, make sure that the engine of your Pro Ceed is off and cold.

You need a spark plug wrench like the one shown in the following picture. These tools are particularly longer than regular wrenches and, some of them are more flexible so that they can get to places that are hard to reach.

  1. Check where each wire goes. You should not mix the wires up, or it will be troublesome to reconnect them. The ignition process follows a specific sequence that should not be modified. You can mark the cables with a marker, some tape, etc.
  2. Disconnect the spark plug wires with your hands.
  3. Turn the spark plug wrench anti-clockwise to loosen the spark plugs (like in the first picture) and take them out. Sometimes, they are really tight. Do not let any dirt enter the cylinder holes from where you removed the spark plugs. If anything falls inside the cylinders, you will have to take it out no matter what, which will be a nuisance.
  4. Put the new spark plugs in and turn the wrench clockwise. Tighten the spark plugs until they are all the way down, but do not over-tighten them.
  5. Once they are down, you must use the wrench to secure them like this: tighten spark plugs with a flat seat (with a washer), an extra ½ of a turn, and spark plugs with a tapered seat an extra ⅛ of a turn. They must be tight but not overly tight. If they are over-tightened, the thread may break.
  6. Reconnect the wires in the same order they were connected.

And that is it. If your engine does not start up properly, check if the wires have been connected in the correct order, since you may have mixed the spark plug wires up.
