fan clutch 280sel w126
Recently I Was On Vacation In Las Vegas, While Travelling My Fan Clutch Siezed Solid, I.e Tha Fan Was Nom Turning At Engine Revolotions, Making A Hell Of A Niose As Well As Pusing Up My Fuel Consumption.
I Remaved The Cast Fan Completely, And Wired The Electrical Fan So That It Comes On At 80 Degrees Celsuis, I Have Now Travelled Over 3000miles This Way, In Traffic, Open Road In Extreme Heat And Cold, And The Engine Temprature Never Rose Above 85 Degrees Celsuis My Question Then Why Did Mbz Install A Cast Fan, If The Car Is Fine Without One, And Much Quiter, Better Fuel Consumption |

There are numerous reasons why automakers kept clutch fans.
A: It was always done that way. B: Dependable electric motors in the '60's used a ton of current. C: Engine power (rotation) was free and constantly available. D: Electrical components required additional electrical circuits, sensors and relays adding cost and complexity to the product. That being said, I ran my '73 220D for 6 years with the electric fan only. Granted, diesels run way cooler than gassers but that was here in Tucson where it gets a tad warm in the summer (defined as "between April and November"). If you are going to go to electric fan only, I suggest you install an aftermarket fan on the inside of your radiator shroud and keep the original front electric fan as it is. This eliminates having to redo any of the wiring or sensors for the A/C. I would also suggest you increase battery power as the fan will draw about 10 amps when running. It may not be much but if your battery is "iffy" then you will be putting more strain on your alternator. No alternator, no cooling and a quick meltdown. Replace the standard fan relay (mechanical) with a newer electronic unit. They are about 10 bucks and an hour of re-wiring but MUCH more dependable. My son toasted a head ($350 for a used head with machine work) because the old relay stuck. I am getting ready to convert my '73 280 M110 to electric fan. I'll let you know how it goes.
