Oh yeah, you have your special radiator.
Daryl M AUG 25, 12:38 AM
Ok, here is my next question. I am now working on my doors. Here is the situation. The 1988 doors have manual mirrors and windows. My 1986 parts car has power mirrors and windows. Unfortunately the parts car doors have broken handles, inside and outside, and bad hinges. The 88 has good handles and hinges. Now for the question. What is the easiest way to get to the hinge bolts? It looks like either the window tracks have to come out or maybe the door skin could give access to the bolts. Any advice is appreciated.

Raydar, do you check the level in the radiator regularly? Did you completely block off the overflow port on the radiator cap?




I wouldn't say you're too conservative. I just trust the front cap more than you do, apparently. Gotta do what works for you.

My front overflow is essentially non existent. I mean, the fitting is still there, but the cap is 20 lb, and non vented. (I don't think I've actually capped off the fitting. I need to check.)
The only place it should ever vent is at the lower pressure cap, in the rear.

With that said, it has been that way for years, and I haven't had any issues. I think I may have added coolant once - maybe twice. And not a great amount. Mostly just topped up the reservoir/overflow.
I've never seen any evidence of an air bubble in the system. No "twitching gauge" or funny noises. No overheating. (It did run very warm on one of our 100 degree days, with the A/C on and at 75 MPH, but that's a whole different issue.)

To directly answer your question... No. I haven't physically checked the radiator level. I haven't found it necessary. I figured that as soon as I crack the cap, any air is going to come out quickly, immediately followed by coolant. Although I suppose I could raise the front...

Radar, thanks for the info. I have decided to block the center check valve in the 20 psi cap on the radiator and go with a 15 on the surge tank in the rear. Sound familiar?

Moving on to the next little project, I am rebuilding my doors. I just ordered the window wipes from TFS, but I haven't been able to find some other parts. First on my list are the plastic bushings on the hinge detent rollers. Anyone know where they can be found?

I am looking for recommendations on hoses/fittings to connect the hydrolic clutch line to the slave cylinder fitting on my Saab F40 transmission. Can anyone provide part numbers or other info?
Thanks

FieroGuru sells an adapter for the fiero line.

McLeod 139160 is a -4 to QD adapter

Rodney Dickman sells detent roller kits with bronze bushings.

I was digging through some parts I bought almost 3 years ago, (yes, I have been working on it that long) and found these. Are these what I need for the clutch line?

You should post a picture of the clutch line connector portion on the transmission. There are at least 2 different types.
