Hi gents!
Has anybody ever replaced a Pulley Driven Cooling Fan with Electrical one?
My concern is how to activate “cut-in” …wires, switches, whatever.
I am going to do it on my Benz w140 s320, and yet don’t have clear picture how to connect electrical stuff.
Any ideas ?
Thanks in advance! - CreatorTopic

It honestly depends entirely on the setup you plan to use. If you’re buying a kit they almost always have decently detailed instructions. I will also depend on whether you want the fan to always on or temperature controlled (wiring for the later will be more complicated).
Here’s some instructions I pulled from the fans at Summit to give you an idea

I definitely choose the one with thermostat, now figuring out where to be connected the thermostat itself…February 19, 2016 at 12:49 am #852096My father in law put an electric fan on his’ 52 Chevy. His had a thermo probe that attached to the radiator. He could set the temp also.
A couple things to keep in mind: you’ll need to remove (permanently) the existing fan. You may need to create a spacer out of washers to hold the pulley behind the fan in the properr position. When mounting the electric fan, make sure those oil lines that run down low on the drivers side of the engine aren’t going to contact it (depending on what engine you have).
These kits are, usually, pretty straight forward. I would tie the power right into your fuse box under the hood.February 19, 2016 at 1:28 am #852098Hope that Thermo Probe is measuring temperature correctly.
I thought it should be some modification on coolant hoses in order to install a Thermostat.
Thanks!February 19, 2016 at 1:59 am #852103The mechanical thermostat (in the metal hose elbow) opens to allow Coolant to flow to the radiator which(through convection) uses air to cool the fluid. If there is not enough air flow at the radiator, the fan turns on. So, even though most manufacturers put the fan switch on the block, having the sensor on the radiator performs the same task.

IF you are going for performance and plan to upgrade (and I mean really) in my opinion would be better to go with the “always on” method. It gives you better cooling especially for turbos (with coolers needing cooling form the air of course). They are easier to set up but again that is if you plan to upgrade your car later.February 19, 2016 at 5:46 am #852125[quote=”W140S320year1997″ post=159580]Thanks a lot !

The thermostat will (or should) already be on your car and will be the thing attached to be block and connected to the lower radiator hose. You can put the fan switch on this housing by threading a hole into it where the switch will go. Remember to have one with clearance for the thermostat. Performance shops could provide you with something or if not go to a machine shop. I’m sure they can make you one if price is not an object….February 19, 2016 at 5:51 am #852128If you disconnect or tamper with the existing fan switch you could confuse the computer. Fyi
February 19, 2016 at 7:11 pm #852188Guys,Many thanks for your suggestions.
Sorry for not being clear when I mentioned Thermostat. I meant Thermoswitch, or an additional Thermostat with some eclectical actuator of Cooling Fan.
It seems to be more expensive and complicated, so it is more simple to go with a Thermoprobe installed at Radiator.
So, no major modifications . - AuthorReplies
