Has anyone tried replacing the thermistic fan with an electric one?
I remember removing the one from my 244DL and just using an electric one in front of the radiator but the temperature probe for the fan just fitted in the end of the top radiator hose and I could not stop the very slight leak. The engine noise dropped dramatically with the fan gone and there was a little more power but I abandoned the attempt in the end.
With the advent of many more electric fans (there's two in my Magna) and a thermoswitch in my 740 for one electric fan, I was wondering if anyone had tried in the 700 series.
Angus did something similar to his 740. If you look at his user profile (angus242142)? on Turbobricks, you should find a link to his post about the work he did.
Thanks mate - I should have thought to look there first!
My GT was done before I got it.
Has the temp sensor in the top hose but I think the hose was pretty new when it was done so it sealed properly.
The other way is to use the T piece and sensor from a Saab 900 which goes in the top hose and has a screw in sensor.
These are usually rusted out, but aluminium ones are available online and I have made replicas in stainless steel, although I am out of Welding gas so I can't make any more right at this moment.
From what I read on the Turbo forums the 940s have two electric fans. There seems to be a sensor fitting in the bottom radiator hose for the fan on the engine side of the radiator. I might see what I can find at a wreckers.
Later 940s just have the one on the engine side as they have a larger radiator. Jaycar make a kit so you can piggy back off the temp sensor to turn on our put your own inline sensor in. Ive fitted it to my 760 as it has the wide radiator but not wired it up yet due to now changing bodies.
At what temperature does the front one kick in? I seem to recall that it's set at a different temp than the thermostat
It turns on only with the ac on above certain temps.
HA, after the trouble and bullshit we had with mine. Bet you don't want to go down that path now hey? @Vee_Que
I'm doing one on my 760. Just with a better control unit.
mine was a good half assed job.
