I've still got the stock 80 amp unit.
Hello Guest, welcome to the initial stages of our new platform!
You can find some additional information about where we are in the process of migrating the board and setting up our new software here
Thank you for being a part of our community!
Does anyone run an e-fan in their 240 with the 80A alternator? I searched through the whole thread and couldn't determine what you guys are running.
I swapped out my stock 55amp in favor of a 240 70 amp when I originally put in an electric fan about 15 years ago. Never had an issue. I'm using the SAAB coolant switch in the lower radiator hose and a 960 fan on low speed. High speed is not currently hooked up.
I would assume most people with electric fans are either running the stock 70/80amp large case Bosch their cars came with or else have updated to the small case Denso/Bosch 80/100 amp units from later 700/900 cars. Any of the above should be fine.
With a cooling system in good shape the fan doesn't run often at all here in the northwest. If I sit at a light too long it will kick on until I'm moving again and it will typically kick on just as I park it and run for a minute or so, but that's all in the summer. In the winter it rarely runs unless I get stuck in traffic or at a long light.
This is on a 242 Turbo with a stock radiator and a watercooled turbo.
Lots of info on it in this thread and others. I've seen them in 900s and 9000s but don't know enough about modern saabs to say for sure.Hey Neptune...a switch in the lower hose is a great idea that I haven't heard of before..can you tell me the model Saab that it comes from? I'd like to try it
Also, does anyone use this sensor? My radiator has a port for this that's just got a plug in it:

Faster warmups in Winter weather with e-fan?
I've noticed,
1993-245 B230F with clutch fan
1993-944 B23F with e-fan
that the 944 takes about 3 miles to come up to operating temperature, and 245 takes about 6 miles at around 5?F (-15?C) when driving at less than 45 mph.
Both have new 92?C thermostats...so I currently conclude that the active fan on 245 is sucking cold air thru radiator, so the returning water is super cold on 245 until enough water heats it. Both radiators good in summer weather.
Yea/Nay?

to reach a "reading" on the instrument cluster temp gauge.
I confirm instrument reading via interior heat output.
>do you block off part of your rad/grille?
Negative...I may just remove fan on 245, and see what happens. My hunch is 245's fan is slowing down cold weather warm-up.
And how exactly is a measurable amount of coolant circulating through the radiator when the thermostat is closed?
Worked perfectly.
Until after I got home last night, low speed kicked on unexpectedly after the car had been turned off for a few minutes... gotta figure that one out.
Mine does that sometimes and on a very hot day it will even do it after 10 minutes. Doesn't effect anything.
Found a 940 with e-fan at the JY. About to leave town, but for $35 I want to grab it.
It has a fan controlled mounted behind the right headlight. 2-speed .....
Does anyone run a 2-speed fan, or does everyone just use the low-only?
I use the low only, works fine in Southern California. Needle never moves passed the 12 O'Clock position.
