Last year I ran over a deer at 55 mph after it was hit and killed by another vehicle. It took off my heavy duty heat exchanger and knocked my lower radiator mount back about 3" so don't be confused by the strange arrangement of the A/C lines which were bent from the straight down position to straight back. The condenser #8 line was crimped a good bit just below the fitting and that didn't help matters, although the A/C still functioned I felt it would result in higher high side pressure and cause other problems.
Rather than stick a used stocker in place (new is $200 plus) I decided to look into the parallel flow condenser which is much cheaper and more efficient allegedly at this point until proven.
The stock condenser is 14 x 24" and about 1.75" thick. The parallel flow condenser dimensions are measured at the tube ends so a 24" wide parallel flow would actually be 25"+ and thus too wide. I opted for a
14 x 22 unit although if you wanted to you could possibly squeeze a 14 x 23" unit in place. The condenser is less than an inch thick so you could mount two in series if you're overly ambitious. I did see such an arrangement on the web involving an upgrade of this nature in an BMW.
This is the 14 x 24" unit.
This is the 14 x 22" unit
Fittings; O-ring insert #6 and #8
parallel flow condenser is metric; M20 x 1.5 (#8) and M18 x 1.5 (#6) Male.
The Fiero is SAE 3/4 x 16 (#8) and 5/8 x 18 (#6) female (lines)
For those who have dysfunctional condensers it will probably be easiest to cut the fittings off and use them to compression fit to a set of barbed fittings for the parallel flow condenser. You will need to cut the barbed portion off of the fittings of course. I decided to skip making it look professional by having the lower barbed fittings butt welded together ~$15 and using barbed elbows with crush collars on them since I was not dealing with lines in their stock configuration. If you decide to fabricate your own lines independent of salvaging the ends from the OE condenser you'll have the challenge of creating a 180 degree bend with the appropriate ends in which case you may want to visit an A/C shop that does custom work, or a hose manufacturer. Also be aware that there are two hose options, standard A/C hose and reduced which has a smaller outer diameter. I'm using the standard hose.
You can get the fittings off ebay but 4 seasons is probably the best one stop shop, http://www.4s.com/Online%20...atalog/Content.aspx#
If that page doesn't take you straight there, hit the catalogs tab and under that select the "part number tab". Next select "Part specification", then catagory (AC fittings) and the rest is self explanatory. Note the dark blue bar in the selection area has a spot for images so select that to see what they're referencing.
