Where are the spark plugs in a 2004 solara 3.3?

Answer 1

First, keep in mind the Iridium plugs in the '04 Solara V-6 don't need to be adjusted, looked at or even spoken to for at least 100,000 miles. If you're not there yet then just keep driving. If you've reached that point then you need to uncover the little buggers. Remove the plastic sound shield from the top of the engine. The front plugs are (sort of) easy to find, they're hiding under each of the three coils you can see on the front bank in line with the oil cap. Remove the coil by removing the single hold down bolt and remove the connector. The spark plug is right under the coil. The rear plugs are a bit more of a challenge. They too are under the coils (same as the front) but getting to the center plug requires a strong will, extreme patience or another wrench to remove the intake runner. Once removed access to the center plug is simple. It's your choice but the service manual says remove the runner. Here's one more option. The timing belt is scheduled for replacement at 90,000 miles. Since you (or a mechanic) will be removing parts and spending lots of quality time under the hood anyway, change the plugs (and water pump) then and don't worry about any of it for another 90k. Cheers
