240 E fan only runs for 3 seconds at a time, temp gauge hot

Kjets, can a clutch fan be installed on my car? I've thought about putting one on, but the electric fan seems to be connected to the ECU and I don't want to upset it by cutting its fan control.

It is not connected to the ECU, and yes you can, but why would you? Plus threadjacking ;-)

1992+ USA 7/9 w/wider e-fan rad/OE setup?

You can use the shroud/clutched fan from the B280 V6 car IIRC for the wide radiator with the redblock IIRC. I *think* that recombining of the junkpile works from memory.

Don't pay much attention to the 7/9s anymore/no incentive to/not paid to often/ever.
Decent enough cars (mechanically, but ugly/dated looking/nasty plastic interior/headliner), worlds cheapest owners.

That said, it's ECU controlled on the LH cars and just comes on waaaay late.
Use a lower temp switch/some other way to turn on the relay worked for me?
Coolest of the factory regina temp switch should click it on a bit sooner since the ECU doesn't control the fan on those cars/switch is a bit more conservative/not so close to the ragged edge helped a lot for me if your radiator's got the spot for it (push in switch of factory alum plastic rad or screw in if certain aftermarket)?
If not, SAAB T in lower hose & lower temp switch works too. Just more hose clamps/maybe somewhat unsightly splice/make sure the SAAB T isn't a ball of rust and decent quality switch (readily available new, just at what quality with all the china slave crap in the pipeline?)

Blades are a little quieter/more efficient on the last revision 2000 P80 70-series version of that fan that fits in the 940 E-fan shroud, but not sure it's worth splitting hairs over that. That said, IDK that it really moves any more air worth nitpicking about. :e-shrug:

I have the kool-aid lincoln mark-8 fans of the most powerful of the cheap/junkyard e-fans that can be possibly crammed into the turbo volvo/more compact passenger car engine bay.
Probably fry the poor alternator/overload the wiring like a sketchy taco truck breaker sub panel/make-shift restaurant kitchen breaker-panel without further reinvention/revision of the whole car/cooling setup.

John Lane went back to stock Aisin T-static tropical clutched plastic blade fan + shroud on the 500+hp rally car from e-fan, can't be total junk? :lol:
Revved up plenty fast with a shaved steel flywheel and close ratio gear box & short forged V6 crank.

For a street car the clutched in good shape probably uses less power honestly & better longevity with stock rad/electrical system. Just saying.

I have the wide 940 radiator/-e-fan setup in my 242, controlled with microsquirt. I have it set to come on at 187 and off at 180. It cycles a bit in traffic but when it's cooler than 90 but it seems to run at 173 going down the road, pretty sure thermostat is 82C.
