Hi,

I would like to replace the spark plug in my 2000 ES300, I could not find any DIY for this tune up project.

Anyone has done this and would like to share the experience ?

TIA,

Either get a flex shaft extinsion and a normal extinsion to reach behind it, or take the upper intake manifold off.

It's always adviseable to take the upper intake manifold off & clean it (to give more power back lost from carbon buildup), and give easy cleaning access to any EGR, Idle valve, and the throttle plate<s> the engine may have.
All of which are routine maintenece.

Thanks for the response. Do you have any pictures to show how to remove the upper intake manifold or to replace the spark plug step by step ? The only post that had step and pictures was for 92 ES, not 2000 ES300.

TIA

Procedure is still the same for your ES. There are 3 spark plugs located directly underneath the valve cover, and all you have to do is remove the cover by unscrewing the 3 Allen head metric-sized screws. Then there are 3 more spark plugs between the engine and the firewall, but as Pheonix mentioned, you'll need a set of extension and flex extension socket wrenches to get to them. If you have long arms and a skinny frame, you should be able to tackle this with not too much trouble, but it's a big pain in the ****.

Thanks, I will try my skinny arm first then extensions.

Seems that removing the intake manifold will be a lot of work, but i rather do it that way than using some sort of extensions and flex sockets.
oh, bump from from the dead. . hehehe

This is for the 95 ES, which is practically the same for the 2000:

Why?

Leve the intake alone if all is well -- I hate messing with major parts on old cars.

It is not hard to do on the 2000.

Success!!! Got to change all 6 spark plugs with the removal of the intake manifold!
Started are 2pm and ended around 5pm. So for the first time doing it I say it went pretty well.
Just a few stubborn screws behind the manifold was a b*&tch!
Overall, new spark plugs and an oil change was a SUCCESS!!!!!
