Title: Aerodonamic Work Session
Post by: Fierofool on July 20, 2018, 07:36:41 pm
I know it's late notice, but Michael and I are going to try to get the Aerodonamic exhaust and transmission attached tomorrow, Saturday July 21.  Raydar will be there if his schedule permits. 

Michael and I plan to be there about 10AM.  Would any of you like to join us to try to get Aerodonamic ready so Michael can do some test flights before Run For The Hills?

I went to this session for a bit. Helped with the exhaust manifolds on the Aerodonamic car, and figured out what was wrong with the AC on another car. Sometimes it takes a geek to figure this stuff out.

By chance was the problem with the air that you fixed on the other car by chance be mine.  If so what was the problem you found. 
Title: Re: Aerodonamic Work Session
Post by: TopNotch on July 21, 2018, 04:24:32 pm
The car is a burgundy GD. The problem was that the negative side of the compressor power wasn't being grounded through the high pressure switch. And that's because a pin was bent on the switch. The pin broke when we tried to straiten it out. So it will have to be replaced. I left to work on my own car at that point, so I don't know if the switch was replaced today or not.

Very sorry I missed this.
Please let me know, as soon as it's decided, when the next work session will be. I will do my best to be there.
Title: Re: Aerodonamic Work Session
Post by: Fierofool on July 22, 2018, 12:12:29 am
We were missing one bolt in the AC mounting bracket.  Michael is going to try to get one at the hardware store.  Probably the next step will be to get the transmission and mounts installed, then the front motor mount.  Then we can align the Y pipe with the exhaust and get those bolted together. 

With that, we can attach the transmission and get ready to lift it into the car.  If the weather will let me get my yard work done, I might be able to do another session next Saturday.

Title: Re: Aerodonamic Work Session
Post by: Fierofool on July 22, 2018, 08:40:24 am
The bolt needed is one of those that bolts the V6 compressor bracket to the engine.  Two are hex bolts, the other is a stud.  Oddly, the P22 only shows one bolt and one stud, but the two hex bolts are the same size. 

They are M10 x 1.5 x 60 hex bolts.  Grade 9.8 and torque to 37 ft-lb.  The diagram can be found on page 268 of the P22 parts manual.  I give this information to save search time because it took me more than a half hour yesterday to find the diagram.  It's in Chassis Group 9.0.

Pat, maybe I need to get you to take a look at the 85SE headlight problem.  Right headlight goes up but not down.  Everything has been replaced in the system.  12 V going to the motor on the DOWN circuit.

Generation 1. 
Title: Re: Aerodonamic Work Session
Post by: TopNotch on July 22, 2018, 08:21:27 pm

Old type or newer type?

Generation 1.

Refer to the drawing below. With the headlight open, connect the positive wire from a 12v battery or battery charger to the wire marked with a red +. Connect the negative wire to the wire marked with a green -. If the headlight goes down, the problem is the relay. If it doesn't go down, the problem is the motor, or the wiring to the motor.

Planning on being there, if the sky doesn't fall on us again. 10:00 sounds good.
I'll try to be on time. Remember, I'm coming from DNA. (That's "Damn Near Alabama.")

If Michael got that other bolt for the alternator to engine bracket, I think we do.  He kept everything pretty well organized as he took the engine/cradle assembly out. 

Forecast for Saturday is low to mid 70's in the morning and about 90 in the late afternoon.  Sunny.  No rain.

I'm not going to make RFTH, so don't throw in volunteer hours to get a car going that isn't going to make the run! The shop will be selling right around that time and I will have to make a lot of things happen on a very tight schedule.

Can we put the Aerodonamic car on the back burner and get Deshoe's car going? I believe he wants to go on TRFH this year. The brakes are still crappy after front rotors and pads and it's running rich. I really need some assistance on his car. Bob has been more than patient with me. Maybe we can work on both?

Post by: Raydar on July 28, 2018, 06:34:51 pm
DeShoe treated us to Old Hickory House barbecue. (Been ~30+ years since I've eaten at OHH.) Thank you sir!

According to the timing light, it appears that the timing was waaaay advanced from where it should have been. (I'm surprised it didn't ping like hell, that way. But whatever... )
Once it was set to spec (+/-) it seemed to idle a lot better. Bob said it "ran like a striped ape". or words to that effect. :D
The fuel pump suddenly sounds like a dentist drill, but everything seems to work well. Mike is going to drive it around this weekend, to make sure it's happy. (The pulsator was removed, so that might have something to do with it. Or it may have shifted since it was installed. Hard to say. For comparison, my Fiero's fuel pump sounds like a Cessna, and it's been fine for over a year.)

The injectors appear to not be stock. Instead of a completely black body, the "discharge" end is silver. So who knows? Maybe the Fiero Store "Tomco" injectors.
Regardless... Bob said it used to run fine on those injectors, so I have a hard time believing that they suddenly started causing problems, out of the blue.
Mike poured a can of SeaFoam into a half of a tank of gas. That concentration should take care of any injector issues that occurred from sitting.

That's the one.  Northlake Parkway.  It's been years since I've been there, too.  Thank you, Bob.  BBQ is probably my Nr. 1 favorite food away from home.

Post by: Slyp on July 29, 2018, 11:38:29 am
No, I have to thank you three guys.  The right guys were there to solve a major problem.  Just to bad a new one cropped up on the test run. I know my wife would not put up with the sound comming from the "fuel pump", we hope.   The last time I heard a sound like that was when I was about to run out of gas.  But the gas gauge says there is half a tank.  Will have to wait till Michael drops the tank to see what the problem is.

Title: Re: Aerodonamic Work Session
Post by: MikeMac on July 29, 2018, 09:24:10 pm
The weird thing about the noise is the intensity of the sound changes according to the electrical load. When you put on the turn signal it changes sound along with the flash. Same thing when you hit the brakes and the stop lights come on. Any ideas?

Post by: Fierofool on July 29, 2018, 09:34:11 pm
Talked with Roger today about the coolant fan running.  He said to disconnect the ground from the low-pressure switch.  The cycle switch up front will take care of that function.
Title: Re: Aerodonamic Work Session
Post by: GTRS Fiero on July 29, 2018, 09:41:26 pm
Are the noise and coolant fan the same issue?  Otherwise, I'd check the alternator.
Title: Re: Aerodonamic Work Session
Post by: Fierofool on July 29, 2018, 09:44:27 pm
No.  Different issues.  You can hear the fuel pump by opening the filler door and removing the cap or placing your ear against the console armrest.

The sound is changing because the other stuff is drawing current, which is causing the voltage to the pump to sag just a bit.
You can measure the voltage at the FP fuse, in the fuse box.
With the box snapped up in it's normal position, it'll be the dark read fuse, nearest the edge of the dash, 2nd from the left.
If you REALLY want to be accurate, you can measure the voltage at the yellow plug, on the firewall, just above the tank. I forget which wires, though.
If the voltage is too low, it will cause the pump to draw excessive current. (Too low voltage can be as damaging as too high voltage, over time.)
I noticed that one of the fusible links had been replaced. If there's a bad connection on that link, it might be what's going on. The fuel pump fuse is always hot. So is the feed for the headlights, and lots of other stuff. I had that same link to act up on my car. A replacement fusible link had a bad connection that eventually failed. (Mine was the big red wire that disappeared under the sail panel, and went to the whole front of the car.)
Title: Re: Aerodonamic Work Session
Post by: GTRS Fiero on July 29, 2018, 09:48:59 pm
Weak electrical connection?  Bad brushes, or whatever the fuel pump motor uses?

Talked with Roger today about the coolant fan running.  He said to disconnect the ground from the low-pressure switch.  The cycle switch up front will take care of that function.

I cut the ground wire for the low pressure switch and there is no fan operation. The ac runs a few minutes until the high pressure switch cuts off the compressor.

Does the fan work at all? 

How did the car perform over the weekend?  Any stalling?

I didn't run it long enough to see if the engine temp switch turns it on for cooling. It does not run during ac operation. It didn't stall at all over the weekend...close to 45 miles of driving.
Title: Re: Aerodonamic Work Session
Post by: Fierofool on July 30, 2018, 05:15:13 pm
It's probably better that it run all the time than not to run while the AC is energized.  The AC puts a lot of extra heat in front of the radiator. 
Title: Re: Aerodonamic Work Session
Post by: GTXVette on July 30, 2018, 06:12:45 pm
I agree with keeping the fan on , at least this Summer. check the sensor that tells the  computer to turn on the fan, Max AC is one engine temp is one ,
Title: Re: Aerodonamic Work Session
Post by: Fierofool on July 30, 2018, 06:59:30 pm
Does anyone have a pair of the old style pressure switches?  Would also need the harness ends with a pigtail to convert back from the new style switches.  I'm wondering if separating the grounds for the switches would make any difference.  Even though both of the old styles were grounded through the common compressor case, I wonder if the high and low-pressure feeds are the culprits because either high or low pressure is feeding a ground circuit. 
Title: Re: Aerodonamic Work Session
Post by: MikeMac on July 30, 2018, 07:36:18 pm
Replacing the switches would involve evacuating the ac and possibly removing the compressor to swap the switches. The fan may just have to run all the time......
Title: Re: Aerodonamic Work Session
Post by: GTRS Fiero on July 30, 2018, 07:37:32 pm
Other than voltage and noise, any issue to the electric fan running constantly?
Title: Re: Aerodonamic Work Session
Post by: Fierofool on July 30, 2018, 09:39:04 pm
It just shortens the life and depending upon the thermostat, it can make it run too cold in the winter.

Title: Re: Aerodonamic Work Session
Post by: Fierofool on October 13, 2018, 07:24:19 pm
Install rear calipers and connect ebrake. 
Install rear sway bar.
Install inner console and trim.
Evacuate and charge AC system.
Wrap a portion of a wiring harness that had the plastic sheathing melted away.
Install the firewall heat shield.
Finish coolant fill.
Check and tighten rear suspension components.
Install air intake and filter housing.
Install cruise vacuum canister and engine bay cooling tubes.

Steve and Jason working with the C500 and the front battery connection.


Jordan and Jason connecting tank to engine fuel lines.


Jason, Steve and Mike trying to locate a ground connection point for the front mounted battery cable.


Mike and Steve both agree that it's not long enough to reach that connection point.


Finally!  The starter is installed.  When the 3.4 block was drilled and tapped for the starter, it wasn't in proper alignment.  The starter was difficult to install, but with all hands on board, we finally got it.


After all that work, it Barked At Us.  A little starting fluid in the intake and it fired but died.  So add to the To Do List, a new fuel pump, which Mike already has on hand.

Others that were involved but camera-shy were Scott and Dave.

The throttle body had tape over the mouth, in the pic that you can see. But it was quite clean.
Don installed "acorn" nuts on the the strut bolts, when he originally built the car. Mike said he really didn't want to modify it, from how Don had it.

The engine bay is really not dirty at all. Mostly dust. (The pics make it look worse than it is.) Don kept it spotless.
I really didn't do that much, due to still having stitches in my hand, but I barely got dirty after being there most of the day.
Once everything is screwed back together, a quick squirt from the hose will do wonders.

No. The sail panels are pretty much perfect.
Other than the unpainted front fascia, the whole car is quite nice, under all the dust, dirt, and tree sap, left from sitting in the yard.
A good wash will make it shine.

Post by: MikeMac on August 16, 2019, 09:06:40 pm
Drove the car around the neighborhood this evening after replacing the axles and rear hubs. It drove surprisingly well!

The "Interim Owner" had replaced the drivers side axle and I was concerned that it wasn't done correctly therefore the replacement. I left the rear sway bar unattached to see if that contributed to the handling issues I had while driving it home from the shop several months back. I will reattach the sway bar and see how it goes.

I plan on getting it tagged Monday so I can work out the remaining bugs.
