My wife’s 2013 Toyota Highlander V6 is just north of 110k miles. I was driving it today and though, hmmm…probably time for plugs. I asked my wife to look in the glovebox at the manual and see when Toyota recommends a plug change. She said the manual recommended it at 120k miles, although I haven’t looked for myself.
What I did look at was the plug location and a couple of YouTube videos on the process to replace them. Upper intake manifold must come off, which isn’t a surprise. It appears the windshield wipers, their linkage, and part of the cowl need to be removed also. Ok, I wasn’t expecting that! Has anyone here performed this? Possibly have some tips?
I may let a shop do it. If I drove it, I’d do it myself. My wife isn’t a patient woman, and I’m not sure I want to do the work with the thought of her wanting it back ASAP in the back of my mind the whole time. Anyone have access to how many shop hours are usually billed for the repair? Thanks.
