...Junk yard used, ebay new, ?. Post back on its performance. My concern is the after market only "has" to last, ...what 90 days. While the OEM last, ...WAG 75-100k. So, based on what little I know, (which isn't much)(and correct me anywhere i'm wrong) i'd want a used OEM, depending on the miles.

Most, if not all, aftermarket suppliers are also OE suppliers. I have no idea who makes Mercedes fans, but it may well be that it's not Mercedes. I have hung a lot of aftermarket rad fans and have never had a comeback. Besides, for the price difference, I can buy 3 or 4 aftermarket pieces. Doesn't seem like much of a gamble to me.

Master, again and still

Anybody on here using one mounted to a cross flow rad, to where you would need to mount it upside down for it to look right, and on a B-body (hint,hint)

I ended up changing the way it is mounted next picture no bolts.Perfet fit i fit it behind the flange it gave me about 1 inch more room between water pump and fan motor.I am using a 3 core alum champion raditor.Now i just have to wire it up.I brought the kit feets suggested.$22.00 at advance auto.I have a already had a flex-a-lite on car wouldn't work with this setup.



Hey, Could you show how you mounted the shroud and fan to the radiator? Maybe a close up pic of the mounting points? That would be great!

i got the fan installed and wired today. it's mounted to a 26" crossflow radiator. like feets, i've tried just about every electric fan out there at one time or another and this thing has them all beat. the electronic temp controller is set to turn on the fan at 185 degrees. it was 95 degrees today and we had the air conditioning running on max. the fan worked flawlessly. engine temp varies a little bit depending on rpm but it kept the engine between 182 and 190 degrees. with the HHR fan the temps would climb up to over 210 with the air on sitting there idling.
night and day difference and very happy with it.
Feets, if your reading this, thanks for the info.

the radiator is a northern cross flow. 26" between the tanks.
as far as the controller goes, nothing trick there. the wire that used to power the HHR fan is now used as the trigger wire for the new one. the sensor is in the cylinder head right now. i'm going to change that though so the fan doesn't run quite as long after shutting down the engine. (heat soak)

So how did you wire the three wires coming off the fan?

i wired them exactly like Feets showed in his first post on the connector side. i ran both heavy wires directly to the battery and the trigger off the thermo control unit.

I like this fan. With all the electronics in it you would think there should be a way to control the fan speed? Anyone have schematics from Mercedes or the vendor?

Talked to flex-a-lite.the fan controller i'm using is variable speed conntroller #31165-vsc which has two wires hot and ground.The hot wire is always hot switched on or not.The fan has three wires hot' ground and trigger so they told me to hook the two hots and lead trigger wire together.The two grounds fan and contoller together.This is as far as i got had to go in the hospital for surgery.Told me i will me in here 7-10 days.Just trying to fiqure out how everyone with a controller has wired there's I brought my fan from a friend who got it from LQK.Lqk told me it is covered for life.(warentty)But remmember no mods to the fan shourd.My contoller also has a builted in relay.I will be running two relays one builted in the fan also one in the controller

As feets said, his shop guy thought that a voltage difference in the trigger line might cause it to blow slower. not variable but 2 speeds.

I hooked up a balast resister in line to the trigger line and tried.
At first I thought it didn't make a difference, but later that day I realized the fan had not spun up to high speeds. I have not tried it again to verify though.

Still very fast at "low" speed, so not sure there is a benefit to the extra wiring required.

Glad to hear it's working out for you!

I'm always open to sharing good stuff I find as well as helping others learn from what I've screwed up.

Well, BAD NEWS. the fan went kaput today and started smoking from the connector area. it worked fine for 2 days. it didn't hurt the wires or anything like that, but the electronics behind the connector got toasted pretty good.
i have a feeling that the trigger wire is not supposed to be 12+ volts. it would actually be closer to 14 volts whem the engine/alternator is running. not sure what else it could be.

Feets, any chance you could ask one of the techs at the dealership about that voltage requirement???

mine is running like that and has been running for nearly a year.

computer shows 15.2 at idle, 14.5-9 at speed. so voltage isn't the issue.

Is yours a real oem or is it a replacement aftermarket?

The sensing line is just the trigger to the built in regulator.

wasn't it a lifetime warrantied one?

See if they will swap it out.
Like I Said, mine has been running at least a year. PRobably longer. I know it is running higher than 14 volts 100 percent of the time.

yes, it's a lifetime warranty. i e-mailed the vendor. of course i had to modify the shroud and they'll probably hassle me about it, but that doesn't have anything to do with the electronics. we'll see what happens.

Sorry to hear that yours fried. I haven't had any problems with mine. Andy and I both run Mercedes fans that were damaged in collisions.

If they give you much fuss, see if you can get a second fan, swap the motors, then send it back. They get an unmolested shroud back.

they said when they get that one back they'll send another one out. so far so good except for the 1 1/2 week turnaround time. (freight from Fl. to Ca. and back)
i went back and looked at the wiring to make sure i didn't mess up there, but it's wired up just like your picture. the only difference is the placement of where it plugs in is different than yours.
with the fan mounted upright (normal position) the connector plugs in on the drivers side with the connector plugging in from the top. in your picture the fan is upside down, but if it were right side up the connector would be going in from the bottom. i just followed your wiring method to hook it up. hopefully i just got a bad fan and there's not something different with the way it's supposed to be wired. i'm reasonably sure if the positive and ground wires had been reversed it would have let me know right away. it's just a guess on my part but if i used the wrong terminal for the trigger the fan probably wouldn't have run at all.
any input???
