Has anybody ran their E55 without a fan blade? I’ve heard it doesn’t do much for cooking and since mine is bad it’s just causing the Whooshing sound. Any thoughts?

absolutely need a fan blade. The engine will overheat without it....

Thank you for the response, I found the took at a local Auto Zone that I could rent to get it replaced

6spd

no problem!

you actually do not need a fan clutch on these cars. As long as both electric fans in the front are working that is enough cooling. I don't run a fan on either of my e55's

Thats good info to know.. It's a bit of a gamble to run your car that way. As I've had an electric fan die out before. It didn't stop, it just got really weak over time. To the point where it didn't cool the AC condenser down. So i can only imagine the engine on top of that. That being said the Electric fans only run with the ac on or when the coolant temp is near 90-100c right? Or were you able to make it kick in sooner?

If i'm not mistaken:-

those front Electric fans to cool the Radiator & A/C condenser,

but how to cool the water pump..!?!, it will blows out in short period..?,,

and what about temp sensor..?, it will always send overheating signal to ECU, isn't..!!

you are correct, I still do keep the fan and fan clutch in my trunk in case the electric fans do die, but I haven't had that issue. My cars have absolutely no problem with temps, Ive driven in 115 degrees in traffic multiple times and regularly do road trips, autox, and canyons. I also have an ml55 which has the same engine and doesn't come with that fan from factory, it just has one large electric fan.

I don't think the water pump needs cooling. I'm just speaking from experience, I have over 50k combined miles without the fan or shroud and I havent had an issue

Any issues with pulley alignment over time?
Pick up any power?

6spd

The real question 😆. What about more power?

cm60k

Yeah..!!!,

I wonder if ECU can even recognize the signal from barbecue laps..

This may have come off sarcastic but I was serious? Car feel any different?

I pulled mine off last week, been running around for a couple days now. I don't feel any difference honestly, and with exhaust and intake mods, no difference in sound either. The car gets quite a bit hotter in traffic, idling around etc. Before, I'd rarely see more than 185*, this morning after idling for 3-4 minutes I saw 205.

There is 1 side benefit I can think of...changing a serpentine belt on a road trip (IE in an emergency situation) is a LOT easier with the mechanical fan off.

I didn't feel a difference in power and if anything pulley alignment will be better without the fan. My car got as hot as yours once and it was because the belt on my 2 front electric fans came apart. 1 of the fans is powered by the motor and the other fan is belt driven off the first fan. Replaced that and now stays at a normal temperature. And yes doing maintenance is much easier.
