I'm replacing this in my girlfriend's 93' RX-7 after it cracked at nearly every seam.
I have a identical unused replacement from mazdatrix.

I tried to remove the old one by removing the entire left headlight assembly, but that area is partitioned off from where the reservoir is.
Then I tried to remove the airbox, but I couldn't get it out and it looks like you would also need to remove the assembly that raises and lowers the headlight as well, in addition to all these other wires and various crap.
Is it possible to get to it from underneath the car?

If you've done this before, please advise me on how you got to it.

Thanks, T/W

 

Through the passenger side fender liner...

 

You know, that sounds about 10,000 times easier than what I was trying to do...
Thanks much.

 

I'm about to do this: will I need to pull the intake as well? The headlight assembly?

You can do it all through the passenger liner. I though I would have to take the bumper off but didn't need to. You can reach the bolts behind the headlight by tanking the plastic surround around the headlight glass off and using an extension and a wobble. Everything else is really straight forward once you get the liner off.

 

I did it completely through the fender lining. Didn't need to remove anything related to the headlight. Took me longer to remove the wheel than the reservoir.

 

It's really easy....Remove the front bumper, radiator, AC condensor, fans, pwr str loop, intake, etc. Take a spot weld drill bit and drill out every spot weld holding the front cross bracing on, including the headlight frames. Push the ring harness up along with the relay box out of the way. By that time, everything is off the front of the car and you should be looking the bottle right in the eye - remove one harness clip, one hose and one 6mm bolt. Waaallllaaa !!

Then again maybe I should of just looked on page S-16 of the manual and saw how the fender liners come off. Oh well, got to so some welding now.

LOL

I got everything thru the fender liner except that short hose that comes with the replacement tank. That can wait for a day when I have my stock airbox removed.

Yeah, I did the same, removed the front passenger wheel, unscrew the fender lining attachments and slipped the tank out.

I replaced the overfill tank with a smaller one from a 1990 Toyota pickup and installed it in front of the intakes. Then routed a flex plastic 3 inch hose from the open oil cooler duct directly to the intake, nice cold air!
