Question how to replace the opti

i was wondering how you go about this, what do i have to remove to get to the opti, and does anyone have some tips to make this easier, so far i have removed the discounted the battery, took out the air intake, fans, and drilled the coolant, is the water pump next? or do i have to remove the dampener? or both? im just going to be replacing the optis cap and rotor,
thanks

You'll need to get the radiator out and the water pump. You'll need to get the pulley/damper off, but you can leave the hub in there.

yea... i did mine without pulling the radiator... just take the fans and shroud out... i had to pull my PS pulley so i could get the the WP bolt on the far left.. i got it out but couldnt get good contact on it going back in... and i didnt want to beat up the pulley so i just got it out of the way...

I usually just pull the radiator, fans, and condensor (no longer in my car) out all together since they are somewhat attached. I usually get the fans hung on a hose or something so I just pull it all out.

That's the air pump bracket ain't it? You can just take that off and leave it out.
