I wonder, is it that noisy in the Mercedes? If it is I'm surprised the yuppies put up with it.




On a hot day when the a/c starts

But for whatever reason it either slows down in speed or I quickly ignore it. At least on a E series it's like that.

Feets, is your radiator a 26" in a 22" core support?




Yes. That's why the radiator is hacked in there. It works.


Thanks, that's gudenuff for me!

I hear those fans all day long.
When the first one fired up today I immediately thought of the hot rod.

Funny how that works.

So you work at a Mercedes parts counter? Hmmm... my '05 Sprinter turned over 428K,000 miles today...I know I'm gonna need to buy a part or two eventually... won't I?

Seriously, M-B stuff is TUFF! Besides serpentine-related parts (water pump, tensioner and idler pulleys, AC compressor and harmonic balancer) the engine hasn't had ONE BOLT taken loose on it! Original injectors, gaskets, alternator, starter, etc., etc. ...

That Sprinter has some miles on it! I'd hate to see the total fuel bill for half a million miles.

Feets, Thanks for the time you took to document the process. That's a great hotrod upgrade. I will definitely find one for my car.


I’m listening.

Priced a used one today at a yard in TN today for $225, fan motors alone are going for about $100.

Shop around or make friends at a Mercedes body shop. The cars these fit on were the cheapest of the breed with some being 9 years old. They should be out there in a variety of yards.

You could always give Summit a call to pick up an 18 amp Flex-a-lite fan for $359. There are all kinds of fans out there that cost more and move less air.

I never suggested it was the cheapest route to go but it works so much better than all the others I've tried. It's a nice fit too.

Feets, is your motor in the stock '65 location, or is it moved back with a later B-Body K-Member? I'm wondering if this will fir a '65 with a 440 in the stock location.

Thanks for a GREAT writeup,
Ben

his is moved back. He has the 67 and up k-frame in it.

Mine is stock, but I have the 5.9 mag in mine, so not sure how it compares. But mine is the deeper fan, and I still have room.

This is a trick question. My K frame did move the engine back a bit. The catch is that my radiator support is bent and twisted badly. The bottom of the radiator has been pushed back substantially. It's almost a wash. If you look closely at the pics you can see the angle on my radiator. Compare the angle of the pulley to the angle of the fan. It's not pretty.



I imagine it would still fit in a car that wasn't butchered like mine. The fan sticks out from the radiator core 3-1/4". If you have that much room between the fins on the radiator and the bolts on the water pump, it'll fit.

I was playing with it again today. My fan is set to turn on at 195 degrees and turn off at 175. I have a 180 degree thermostat.
I heat soaked the engine and let it idle. With minimal water flow, a radiator that's half clogged with crud, and the fan running I was actually able to cool the engine down below the thermostat's rated temperature. It took a little while but the fan turned off at 175 on the 180 stat. My engine temperature sensor for the fan is in the water pump housing.
I wonder what it'd do if the radiator wasn't full of gunk...

I think the best thing to is to measure the distance between your water pump with pullies on it to the core of your radiator. Some cores are thicker than others.

I was playing with it again today. My fan is set to turn on at 195 degrees and turn off at 175. I have a 180 degree thermostat. .

I put an aluminum radiator and dual spal fans on mine, 440 in a 68 charger. At first, I had the fan relays turning on and off with a toggle switch and kept my 160 thermostat in...I finally got around to installing a temp sensor that turns on at 170 and off at 140. At that time I pulled the thermostat, cut out the spring/middle assembly and installed just the flat outer ring in the wp housing. temps much more steady now than when I had the fans on all the time and was relying on the thermostat. For my car this setup seems perfect, when I start driving, even pretty slow, the temp drops enough so that the fans are almost never on when I'm moving and don't come back on unless I'm at a light or stopped for more than 3 or 4 minutes.
I was curious if you think that running the temp sensor and thermostats together could confuse things a bit.

on another note, I don't know if all 440 stock WP housings have this, but my 71 housing was from a car that had the idiot lights so I have the standard port for the factory temp gauge and I used the larger threaded opening for my temp sensor, didn't have to drill or tap anything.

I don't like running the engine too cold. I also need to walk a fine line between flowing the water too slow in the engine and too fast in the radiator.
We have major heat issues in Texas that you're not going to have in NY. 100+ degree days are common and it doesn't always cool down much at night. If coolant doesn't spend enough time in the radiator it's not going to drop any heat. Instead of fiddling with different size restrictions to get it just right for the ambient temps and then have to mess with it again when the weather changes, I'll stick with a thermostat.
When I fire this thing up, I want it to hit operating temperature quickly for better street manners.

I will reset the fan temps to come on at 190 and turn off at 180. That will regulate temperature properly and give the fan some down time.

I can't seem to find that fan anywhere. Even with the link you gave me. Are there other Mercedes cars that use that fan?

I wonder how well the aftermarket replacements hold up. It would make it a little easier to source the part if you don't have access to a Mercedes junk yard.

Do you see the new after market replacements online?

Will the aftermarket fans work as well as the factory one?
