Hello everyone one, I owned 2 Fiero's back in the 80's, had a 1984 SE that I put over 300,000 clicks on, traded it in for an 88 with the 4 banger in it, reason like the 5 speed found the 4 speed always revving high on the highway, I ended up putting 430 clicks on the iron duke and never touching the motor. Anyways my question is on this 85 GT with the V6 in it there are 2 pipes coming out of the trunk, engine side going into the engine compartment and not hooked up to anything, no idea what that can be, maybe someone can explain what they are. Picking her up today but have to fix the tranny line under the drivers door first, leaking big time. Thxs for the help and looking forward to reliving a bit of my passed and what better way then starting with a Fiero. Jim

Yep. If you look under the passenger side trunk carpet you will see a blower fan motor. It blows it along a tube (which is formed by the sheet metal in the truck) and into those metal tubes you are seeing.
That rear fan is kind of useless. Pull it out and check the metal behind it. chances are that you'll find cancer back there. You can remove the rear fan without consequence.
It's just a basic drum fan that flows cool air from the trunk over the electrical components most likely to fail due to heat.
The air that the fan blows is drawn from the area behind the wheel well, not from the trunk itself.

Arn, that might be your opinion, but not one shared by many (most?) who have the factory V6 in their '85-'87 Fieros. That plus the fact that you no longer even have the V6 back there.
And Thunder1295... please don't start two different threads on the same topic.

johnyrottin.....the duct is actually plastic and lays along the shelf at the front of the trunk Arn...the fan is very beneficial with the old style alternator on the pre-88's. If its not working, alternator life is decreased dramatically. It was eliminated in the 88's because the CS series alternators run much cooler.
Olejoedad, it is also beneficial to the ignition coil and ignition control module. Along with the CS alternator of 88, they also moved the exhaust away from the ignition coil and distributor and shielded the exhaust. That combination of changes allowed for the elimination of the engine bay fan. I know you knew that but just didn't post it.

My 87 GT has the fan and cooling tubes My 88 GT does not. I have replaced the 88's GT alternator 3 x while the 87 is still running the original alternator. Use your own judgment as to its benefits.

When I had my v6 I disconnected the rear fan. Under it was cancer which I had to cut and fix. It is intended to blow air at the coil and the alternator, however, I moved my coil to the firewall. The alternator did fine. You'll find that the later cars did not have the blower. 88's I believe none had it.

The fact that 88's didn't have the blower/fan has no bearing on what can or should be done to stock '85-'87 V6 Fieros. This has been addressed many many times in this forum and twice in this thread alone!
