tuner4life Haha, It's all good! Just looking through all the old threads for some motivation/reference pictures and I start to wonder if anyone even has their cars anymore, or if they are even alive.. This place gets no traffic at all anymore.

Your car is super nice btw. It's come a long way. The floor/trunk repairs are motivating to see as I'll be doing the same exact thing in the coming weeks. Already have the POR15. It really is great stuff.

And I have to ask for old time's sake.. You mount that SPG kit yet?

You read it all That's dedication right there

Thanks, by the way for posting - I appreciate the feedback, it is nice to hear this might be useful or at last entertaining to people

This is my first c900 and as I have floundered around, I mean, uh... fixed it up, I have learned loads about the car. Of course thanks to the Bentley manual but mostly with lots of help and support from the interwebz and Saab community here and elsewhere - so I am glad if any of this helps anyone out with their projects or inspires anyone to fix up their Saab...

My goal here is to make it nice but on a budget - honestly I didn't expect the car would become as nice as it is now... speaking of - I plan to post lots of updates to the thread soon. Just been very VERY busy But there are lots of good updates done to share, as well as some that I will be working on hopefully soon!

stay tuned!

9Kwrecker When I jump the thermoswitch on the radiator it makes the passenger side fan come on. I don't think I tried jumping the other switch up by the distributor, for some reason. I'll have to try that tomorrow.

Did you jump the other thermoswitch for the A/C I mentioned ? It usually has red or black rubber boots covering the wires where it plugs in, on the other side of the radiator, there's those two hoses with the metal junction in between... near the distributor ... I was under the impression that is the A/C thermoswitch...

While troubleshooting the cooling/fans on my '88 900S, I found it setup like this except the passenger side fan was controled by the radiator thermoswitch. I can't recall what I'd read in the manual at the time.

I removed some of the AC system, including the drivers side fan and thermoswitch in the upper rad hose (which was a corroded mess). In hindsight, maybe I could have jumpered the leads for the AC thermoswitch and then controled it directly from the AC switch on the dash.

9Kwrecker From what I've been able to gather, the two fans aren't supposed to come on together. I think the one on the driver's side is the A/C fan and that's supposed to come on only when it's warm.

I was told there's a plug I could jump to make it be manually operated with the A/C button since I've never had A/C in this car since I've had it and removed all of the components when I had the motor out.

If I jump the thermoswitch on the radiator the passenger side fan comes on right away. All other switches/relays/fuses were all checked and found not to be at fault. I had the fan off the radiator on the ground and I put 12V to it and it spins, also spins free no problem.

I find it interesting that both of your fans both come on at the same time. Hopefully someone else can weigh in with their experience.

abdukted1456 honestly, I didn't notice the temp gauge.

When this happened, I was sitting in a parking lot idling just checking my email, and I suddenly smelled that burning coolant smell and saw a bunch of white smoke coming from the under hood... immediately shut the engine off and before I could step out of the car I saw about half my coolant all over the parking lot

I do know it was reading high on hot days, unless I was moving along so fresh air was hammering that radiator doing most of the cooling work! but as soon as I would get to stop and go, traffic lights, it would climb quickly.

by the way, there are two fuses, #6 and there is #20something I think for the A/C fan... check both, and also the relays, and there is the thermoswicth on the upper left/driver side of the radiator plugged right in below that tiny hose, and also another thermoswitch in the middle of the large hose coming off the upper right/pass side of the radiator. Did you check all those, jump each switch, and it still doesn't come on? Then I would disconnect the battery and try to spin that A/C fan by hand and see if it's any good...

I don't know if they are supposed to, but both my fans come on together when coolant heats up. My A/C never worked since buying the car and I never bothered fixing it since it's a convertible and only gets driven on sunny, top-down days (unless my 9-5 is down for repair.)

9Kwrecker Awesome work!

I just got the cooling fan working on my 91 this weekend. I have no A/C in my car and the easy way of jumping the plug to make the 2nd fan come on with the AC button wasn't working. So I currently have one fan, but that's better than NO fan.

Just curious, when you were boiling over, what was the temperature gauge telling you?

abdukted1456 THE PROJECT - IT'S STILL ALIVE!!!!

Just finished up a bunch of work and I have (I think) finally all the parts to get my SPG kit fixed up and put on this summer!

I thought I might have a coolant leak and the car was running a little too hot - I had used fluorescent coolant dye but after going over the whole engine bay in the dark with a UV light, the only glowing coolant to be found was in the reservoir! Hmmm...

Then, on a hot, hot day - it finally happened. The coolant boiled over and I almost had a serious disaster. Thankfully I was just down my street from my house.

I found the #6 fuse for the radiator cooling fan was blown - easy fix, right? Well it actually was a symptom of a larger problem.

Thanks to turbocon86 for the tip - I used a piece of wire to jump the connections at the radiator thermoswitch to test the fans - they both fired up although the car would shake when they started like it was a serious drain on the electrical system. So I suspected the thermoswitch in the radiator, since the fans worked.

But after trying this test several more times, I noticed the #6 fuse would blow again within 30 seconds or less, sometimes as soon as the fans started! Relays seemed to be working just fine, so at this point, I was pretty sure that the thermoswitch was OK but the fans themselves might be a problem...

So I tried to spin the fan blades by hand (disconnect your battery first, just in case - if you like having fingers!) and the left/driver radiator fan was definitely a little stiff, didn't spin too freely... but the right one took some serious force to make it turn, and it did not spin freely AT ALL. So the power needed to make it move must have been too much, blowing the fuse. Radiator can't cool enough with no fans, and BOILLLLLLL!

A HUGE HUGE HUGE thanks to turbocon86 for the diagnostic tips and for a spare set of fans!!! Could not have done this without the tips and parts!

So after much cursing, and drilling out rusty, stripped screws and rounded off bolts... I finally get the fans out, only to find that behind a fan the radiator was a little crushed and had a big, fluorescent green spot. And it was wet.

More cursing, back to the local Saab shop to get a radiator and some other goodies. More trips to the hardware store after more rusty bolts, and a broken screw extractor and snapped drill bits...

Finally - a bit more swearing, beer, and cuts and bruises on my arms and hands - I now have:
  • a shiny, brand new radiator with brand new bolts/nuts etc
  • beautiful, free-spinning used cooling fans, with brand new bolts, washers etc
  • some brand new coolant hoses
  • some new hose clamps
  • a brand new thermoswitch
  • some new fuses
  • new thermostat
  • cleaned up t-stat housing (it was nasty, trust me)
  • removed the coolant reservoir and cleaned it out, looks fantastic!
  • removed a nasty mouse nest found under the coolant reservoir, yuck!
  • and of course, brand new coolant
  • deleted the noise suppressing capacitor on the ignition coil, as I never listen to AM radio and it looked rusty and quite suspect, might even have something to do with a mysterious battery drain I have been dealing with.

MikesAERO Hrm im thinking of using the dark grey color for my 9000 aero carpet! anyone have any opinion of using this stuff to turn the grey carpet black while its in the car?

SOAB LOVE the interior dude!! Now how about that exterior?! :P Serious question though, if I do a full POR like you did on my interior would you put any new/better padding o sound deadening down? Was the issue of the floor rusters the material they wee made out of or the inherent design of the car?
01-29-2012 03:20 PM
J-Rod Just read the whole thread. (well, most of it)

So. Much. POR15!

The stuff is great. I've coated the whole interior, underside, trunk, wheel wells of my Mustang with it.

Great project! Awesome work! Can't wait until I can get a c900 convertible.

Saab fanatic I've had a great time reading all 31 pages of this post. please forgive me for stating yet again what a sensational job you have done with the interior!

I have just purchased a 1984 900 aero with an interior is isn't perfect (but a darn sight better then where you started) and now I am convinced that I can make it look new again myself, without simply replacing the seats with new leather!

I just hope i don't have the same rust issues you have had.

keep up the good work

No updates though, on work or improvements... I got a little sidetracked with my new little daughter!

BurnsSide42 What panel is damaged? I have an extra set of the center 6 laying around - I need to put them on the flea-bay to sell them all off.

SEM makes an epoxy filler for plastic parts. You can get it at Autobody Supply in Albany. I've used it on deep bumper scuffs and it holds up well.
