Hey guys,
On the simpler side of things it would make the 240D a LOT quieter... I took my fan off the pulley on a real cold day just to take it out and see what kind of difference it made, should of had my decibel meter with me because it was a huge difference... |

I did it.
A 300D clutch/fan setup (purchased from a forum member) will bolt directly on the 240D water pump. All you need is shorter bolts and knuckle bandages. Flat washers under the lockwashers help too.
Definite noise reduction. Power increase inconclusive. No engine temperature problems. If a viscous clutch driven fan weren't better they wouldn't have used them on the vast majority of cars since the 60's.

I have a fairly low mileage, 77 300D parts car with one, maybe I'll see about swapping it into my 79 240D. How would I know if its any good, spins free now

Some of you remember PEH telling about driving his MB half way across the country after an electrical meltdown. He left the engine running at night and only drove in the daytime.
Taking off the solid mounted fan and relying completely on an electric one would be a step backwards for me. JimSmith told about driving his manual MB during college for a long time by always parking it on a hill so he could roll start it when it had starter problems... I really like the basic feeling of being able to count on the Mechanical parts of the car to get me home.... I have a love/hate relationship with electricity... mostly hate. LOL |

I doulbt you will see any difference in mileage if you put on the clutch fan. (Although I have a clutch fan on my 300 na equipped 240)

I doubt that an electric fan will save fuel economy over a viscous clutched fan of the appropriate size in hot weather at least.
The electric fan will draw current activating the alternator. The rbiggest eason, IMHO, most cars have electric fans is that so many now are front drive with transverse engines where a mechanical fan will not work at all.

I put a clutch fan on my 81 240D.
Didn't notice any difference. Now the N/A 300D radiator..... Jim

It's also easier for manufacturers to integrate an electric fan's operaton into the engine control system, as many cars now regulate fan and AC operation through the ECU. Of course this also adds an expensive electronic component and potential failure point into the cooling system. Happy Motoring, Mark

Clutch fan
IF you're actually in State College, you don't NEED a fan -- for another four months. At the suggestion of my friend and certified MB specialist, I remove mine at Thanksgiving, and put it back in around Memorial Day. I'm in Milwaukee, and we won't see 70F again until April or May.
I have a short commute, and no traffic jams to speak of; but my 240D couldn't even keep the thermostat open at speed on the Ohio Tpk in january ... on my way back from PA, where I bought it. HTH. --frankb |

Huh, well I'm glad I didn't run out and start swapping fans, maybe I'll rethink this, thanks

I might consider changing my '84 300TD's clutch-fan for a 240D fan, but the TD also has a working AC, so as long as it's not broke, I'm not 'fixing' it. Happy Motoring, Mark

For the record, my 409d van with a 617na had an aftermarket electric fan on it when I purchased it. It could not keep up with the heat load on long hills in the summer. I replaced it with a direct drive fan on a waterpump from a 115 617 and the difference in cooling was substantial.
