Spark plug location

Featured Replies

Hi everyone, I was looking to see where the coil packs on the Alphard 2.4 hybrid were located, to identify where the spark plugs were. First thought were its under that air filter box, however I thought I'd check with people who have changed them rather than guessing.

Regards

Personally, as I don't have your model, I would look at amayama.com and search your model for coil, pack, spark or plugs - one will bound to help.

Yes, they are under the air filter housing

Yep, on the 2.4 hybrid the coil packs sit on top of the rocker cover and access is mainly from the airbox side, so removing the air filter housing is usually the first step to get decent access to the plugs.

Once the airbox is out you should see the coils lined up on the head, unplug and unbolt each coil to get to the plug underneath. Worth noting the trade off is it is a bit fiddly rather than difficult, and it is easy to crack old breather hoses or tug the MAF wiring if you rush the airbox removal, so take your time and label any hoses you pull off. If you end up doing the job, let us know your exact model code and year and whether it was the 2AZ based hybrid, as there are a couple of small layout differences between variants and it may help another member

thanks

Glad that helped. Just to add a couple of practical tips: on the Alphard 2.4 hybrid the coils are indeed beneath the air filter housing, you normally remove the engine cover if fitted, unclasp/unbolt the airbox, then you can access the coil packs and spark plugs. Work with the engine cold, disconnect the negative 12V battery terminal, label/unplug coils before removing so you don’t mix leads, and use a spark plug socket with an extension and a good ratchet to avoid dropping anything into the well. As it’s a hybrid, steer clear of any orange high-voltage wiring or components.

If you want a bit more hand-holding, post a photo of the area (avoid showing any VIN/plates) and someone can point to the exact bolts/clips to undo. Let us know how it goes so others can benefit from your experience.
