Spark Plug Replacement

[RX300-2001]

I have a 2001 RX300. I managed to replace 4 spark plugs, but I can't physically get the rear passenger side plug and rear middle plug out. Someone told me that I have to remove the throttle body to replace the two plugs.

I am working on the ground, lifting up the car on jack stands.

I think, if I had a lift, I could maybe do it.

Anyone else tried or have any information?

Thanks.

by the way I did it from the top and used a 2 inch extension, seems the perfect length. Good luck

I'm pretty sure I did remove the throttle body to do the rear plugs, or I already had it off to clean it. At any rate, you

don't have to remove the intake, it's not a piece of cake to do the rear, but definitely doable.

Did not need to remove the intake. It's definitely awkward to reach the coils/plugs at the back there but it's doable without removing the intake manifold.

Lenore,

Thanks a million for the hyperlink. I printed it out, and started early on Friday morning. I was able to do the front three real quickly. The rear three took more time, obviously. It took me about three hours in total, including some water breaks every time I wanted to "snap"...lol The plugs that came out (120K miles) looked fine. They were all burnt in the same way, no oily residue on any of them. :) One thing the hyperlink instructions doesn't mention is that in order to do the rear three plugs, you need the plug socket, and two, 2" extensions. You need to start lowering that in the plug well, and attach a second 2" extension as you lower it into the plug well. Also, I used a piece of foam 2" thick X 12" wide X 48" long. I place that on top of the motor and hood catch and laid on it. I could see how laying on that hood catch would tear open your belly. Anyway, I wanted to chirp in and give you a huge THANK YOU!
