Subject: Re: how to access air filter, trans. fluid ('87 900)
I would like to meet the Saab engineer who designed the air filter assembly
in a dark alley after coming out of the pub one night...
It is a bitch to get the air filter out/replaced. You are on the right
track: take off the plastic bellows that runs from the top of the top of the
air sensor plate to the intake manifold (or turbo if you have one). Then
remove the six (I believe) phillips screws around the outside of the air
filter assembly. VERY CAREFULLY lift up the air sensor / fuel distributor
assembly to get to the air filter. My 2 cents: remove the four plastic
(read OLD BRITTLE EXPENSIVE PLASTIC) fuel lines from the fuel distributor to
the four fuel injectors first as they do not like to be bent; also be
careful not to snap off the 4"-long plastic tube that extends down into the
center of the air filter when you are removing the top (I broke mine off,
doesn't seem to make any difference, I just hate breaking things
unnecessarily). Another tip for you: if when removing the fuel injector
lines you happen to loosen up the fitting that screws into the fuel
distributor instead of just the fuel line -> fitting connection, replace the
crush washer underneath that fitting with a copper crush washer... I have
found that once unsealed, the old metal-and-rubber washer does not properly
seal and can inject some air into your system.
Pretty ridiculous procedure just to change the air filter! The good news is
that the air filter is about the same size you'd see in a dump truck so you
don't have to change it very often.
