    2001 9-3 base, temperature gauge would drop to zero after about 5 minutes of driving and stay there until engine is restarted to which it performs normal before repeating the cycle. Replaced thermostat, still doing the same thing. Coolant temperature sensor?

    After 30k miles with almost no issues, my Saab has decided that it isn't getting enough attention, lol. Concurrent with some charging system problems that are now solved-ish, I have a relatively slow coolant leak. Do I just need to replace this hose (video attached), and what is the part I would...

    Redoing some wiring and noticed in the wiring diagrams that they changed the radiator temp switch from directly switching power to the cooling fan to making it just a trigger for a relay . What was the reason for the change? Was having the current going through the switch to the fan damaging in...

    Hi everyone, I just got a 2007 combi 1.9 TiD. The problem is that the engine temp gauge does not get to the middle when driving and sometimes drops to the bottom. I have no CEL on the dash and the fuel economy reported by the computer seems to be normal. Also, the last time I checked the...

    Hey all! New to the community and world of Saab’s. Thermostat replacement on 9-3 1.8t 2008 - smooth process right up until refilling the coolant. Noticed the coolant was leaking pretty much straight back out almost directly under the thermostat housing Now, when I put in the new...

    Hello all, Still pretty new here but enjoying my Saab quite a bit :). I bought it knowing that the temperature gauge was slow to rise, but the seller said he had had it verified from his mechanic that the car was getting up to temperature and he replaced the thermostat in that same visit (I have...

    So I recently replaced my thermostat, because my engine temp was always at the lowest when driving on a motorway, and in city traffic it would fluctuate a lot. Replacing the thermostat fixed the issue, well I thought it did. It warmed up really well, and stayed in the middle of the temp gauge...

    So my wife got back from running errands tonight & said "you gotta get out here & look at this." Smoke is billowing out from under the hood. Open the hood & I notice the coolant reservoir has split at the seam & is opened up like a clam shell. It doesn't look cracked. Literally split at what...
  14. NG900 & OG9-3 Performance, Mods & Tuning
    (refer to WIS Radiator Fan System- 2 speeds, list of components) Background: I have a 1999 2.0 93 (FPT,LHD). Before recently changing thermostats (Saab or Wahler or better please** see footnote), I didn't realize the old one was just wide open and likely had been for years before I got the car...
  15. NG900 & OG9-3 Workshop
    Hey everybody. Last week when I was driving on the hwy, I saw the CEL go on, and watched the temperature gauge quickly fall to the bottom. I pulled over and checked the code. It was a P0116 which is something like "temperature sensor circuit failure". So, I ordered a new thermostat and a new...

    Hi guys, I seem to have an engine temp problem. 2008 9-5. I was doing a lot of stop and go errands today, and when I left the last store the car did the "bing-bong" and I looked down expecting to see something on the dash or an idiot light. Nothing. Then, when I got home I noticed the fans...

    06 9-5...odd issue that I've seen on the forums but while my symptoms are close, I don't get a CEL ever. SYMPTOMS: On cold days (starting to happen now), the temp gauge will rise to about 1/3 (normal is 1/2) and sit there. If it stays there for about 10 minutes it will drop to...
  18. 9-3 Sedan, Cabrio '04+, Combi, 9-3X Workshop
    So my ignorant self from 6 months ago didn't know there was a difference between the orange and green coolants. So I topped off the coolant in my 2005 9-3 with green. Seeing as it was November in Minnesota, I had no issues with cooling. Fast forward 6 months, It is now April and my car has...
