SPARK PLUG REMOVAL .... HAVE YOU SEEN HOW MUCH OF THE CAR YOU HAVE TO TAKE APART TO CHANGE THEM~?

Though that MAY be possible, how are you going to get the coil packs out????

 

Notice that @taxidriver50005's profile says "Location: GB".

Then see also post #17.

 

Right. Taxidriver's method will not work on North American Gen 3s.

 

Yeah, remove the coil hold-down bolt, pull the coil up to remove and “bump”: it hits the cowl, about an inch too low.

You can get slick at getting all this stuff removed, but every time you mutter a special “prayer”, for the Toyota engineers and quality control people, who let this stinker go.

 

Oh it's even worst for certain V-6 Toyotas like my daughter's Sienna and son's Rav-4. You have to remove the wipers and both cowels back there, then you have to remove the exhaust manifold in order to reach the back 3 spark plugs! (And on older cars you have to be ready to replace a few ignition coil connectors as the heat makes the plastic brittle so they tend to break when you try removing them. I teach folks to use a pick or very small flathead to lift up on the tab and don't even bother squeezing the other end, which can make it break.) I saw a video of a guy changing plugs in a Lexus v-6 and every single connector broke....he was removing them wrong, of course.)

 

For something that will run 150,000 miles or more, plug access is the least of our problems. What I did was call around and found a dealer who would do it for about $100. Of course that was back in 2016 before other things started failing. So just wait and do it with your brake booster, head gasket or walnut blasting.

 

Isn't walnut blasting more of a thing for direct-injection engines?

Last time I had my intake manifold off, there was some carbon around the head ports right where the manifold attached, but the valves and all downstream of the fuel injectors were squeaky clean. Yay top tier gas....

 

Yes! I second all this.

Changed the sparkplugs on my 2010 Toyota Camry 3.5L V6 SE recently and the Prius was EASY compared to accessing the rear bank of the V6 tucked under the windshield wiper cowling.

Broke a few of those brittle plastic connectors too, but didn't bother replacing them.

Alfa Romeo V6 required same..when changing spark plugs

By the way, when i had Prius plugs replaced at dealership they charged 39.2Eur for the work. That does not sound like time consuming task at all. Clearly less than half an hour with their standard rate. European model somehow different(?).

 

I had an old Ford Bronco II with the 2.8L V6. I put new plugs in while the engine was out, which was super easy, and then as I was lowering the engine into the bay, I watched them sinking out of sight, and thought to myself, "what will I do if I ever want to change those again?"

It looked like 1, 2, 4, 5, and 6 would all be challenging but possible, but 3, fuhgeddaboudit.

And then I thought, "did they really not think of that?" And I started poking around the front end, and turned the steering way to the side and looked behind the right front tire, and there, up in the inner wheel well liner, was a little hand hole, with spark plug 3 sitting right behind it.

 

When I had to check out a Chrysler Pacifica Plugin, I just checked one of the odd numbered plugs and, since it looked good, I assumed the even ones were good too. Here's why.

Makes the Gen 3 Prius look like a piece of cake.

 

But hey, their igniters are bendy!



If we could get those, Gen 3 Prius would be a piece of cake!

(I did a double take and backed up the video and frame-stepped it, thinking "did I just see that?")

V6 engines do not belong in transverse applications

 

Yes, I saw that. Well, saw it 1st hand even a few months ago. And I totally agree. Why couldn't the Prius coils bend like that? What a time saver!!!

 

Why won't they just design it to be easy to work on???

 

Toyota won’t be able to reap in the ROI from master mechanic courses and certification fees. Plus cramming things physically thought to generate labor hours for fees.

 

Another fail is the block heater location, really tough with all the stuff around it. Finicky design too; methinks immersed heater element is superior, to Toyotas external-with-heat-transfer-grease design.

 

Does the G3 have wiper alignment marks on the windshield for wiper arm re-installation?

That makes it pretty easy.

Can you lift the cop high enough to remove the cop boot from the cop body and then sneak the cop body out?

 

No. I just put a corner of masking tape right at the tips of the wipers before taking them off.

It took me a long time to figure out, by "cop" you mean "coil". To answer the question: pretty sure no, you're screwed, have to take all the crap off.
