How do you change the spark plugs on Acura MDX?
Changing spark plugs on an Acura MDX engine is a simple task with few complications. Just a few items need to be disconnected and replaced, with a few steps and your job is done.
- Suitable spark plugs
- 3/ 8″ extension bar
- 5/8″ spark plug socket
- Torque wrench
- Spark plug gapping tool (if not pre-gapped)
Remove engine covers
Lift the hood. Remove the engine covers if you have them. Move to the right and around the rear of the engine bay. Remove the front and back wiring circuit covers.
Detach the coils
While changing spark plugs, detach all the coils. Unscrew the 10mm nut that is holding the coil in place. Once removed, gently twist and pull the coil to release it. The rear side is slightly more perilous, but not significantly more difficult than the front.
Replace new plugs
Put together the spark plug socket, extensions, and ratchet on the front three cylinders. To engage the spark plug, insert the socket into the spark plug hole. If your spark plug socket no longer has the rubber insert, you will need a pair of long needle tip pliers to remove the plug once it is completely backed out of the threads.
A magnetic-tipped telescopic wand can also be used to extract the spark plugs. Putting a universal joint between the two extensions for the back three plugs will make it much easier to insert the socket and extensions into the hole. You have to be extra cautious since removing the spark plug without the rubber grommet in the spark plug wrench may be difficult.
Apply a tiny quantity of anti-seize compound to the threads before attaching the new plugs. Thread them into the head gently using only the socket and extension. Tighten to hand-tight. But do not over-tightening, it may pull the threads out of the head.
Reinstall the parts
Secure any tools that may be on the engine or lying about after installing all of the essential parts. To guarantee good functionality, start the engine. When you’re finished, reinstall the engine covers.
- Your engine must remain off and cold.
- Do not put excessive pressure while pulling out parts from your engine.
- Remain extra careful working with the wrench.
- You should use gloves for your own safety.
