Default -Bad Fan clutch

Hello everybody okay so this is what happened about a year ago I had my water pump and thermostat and thermostat housing replaced buy a European specialist mechanic who I felt I could trust to do the job I've had my car worked on before from this guy who had done a few major Automotive repairs in the past so I felt that I could trust him so anyhow ever since I've had the car I've noticed that the fan was always loud and I never really thought anything of it but I had my local mechanic look at it and he said my fan clutch is bad and now my water pump is starting to fail because my thermostat housing is leaking don't you think that my mechanic that did this water pump job should have replaced the fan clutch to begin with seeing how loud the fan was? I'm so ticked off about this but yet I never knew it was an problem and yes I've gotten crappy gas mileage because of it. I never knew why until now SOS before my water pump goes . . . . . . . . should I replace the water pump now just to be safe even though it was done last year because it might have weakened the water pump from the bad clutch fan what do you think? The water pump has ways been a little noisy since it was replaced Sos . . . . .

Hey guys just an update sorry for the delay as I'm not on here that much about a month ago I did have the water pump and thermostat and thermostat housing replaced along with the fan clutch because it was the original one I don't have any more antifreeze leaks but other then that I think the problem is fixed now.
Some people say that when you develope an anti freeze leak on these cars regardless of where it's coming from it's a sign of premature water pump failure that's why I went and replaced the water pump and thermostat again and housing to give myself peace of mind game over no more anti freeze leak problem solved!

You said the fan clutch is loud.

What kind of noise was it making? I would check for damage to your fan shroud, and hose that clips on behind the shroud. (Or even damage to your radiator)

He could have done a bad job bleeding the air out of the system, which can pre maturely cause the water pump to shit the bed. This might even cause the fan clutch to fail sooner than later as well..

Most mechanics will try and bleed the system once. (Not a good idea on these cars)

Would you mind PLEASE using some punctuation next time you post? Holy shit that's hard to read.

Yes, you should replace the water pump with a Stewart high performance unit. This is pretty much the go-to water pump:

Bimmerworld also has a fan delete kit, or an electric fan conversion kit, both of which eliminate the fan clutch.

If anything else is failing, or leaking, or cracked, replace it.

So, are you saying whether a hose clam wasn't tightened properly and caused a leak that you would buy a water pump because of water pump failure?

I think everybody else was able to read it just fine any how thanks for your suggestion on the water pump I did not go with the Stewart one I went with the Famous Hepu German aftermarket water pump and thermostat along with thermostat housing and it seems to of fixed the problem.
These cars can also develop leaks after you install a new water pump because sometimes they don't always Evacuate the air out of the system properly but that wasn't the case on this.
I went with an oem fan clutch made by Behr I've had zero problems since the new install no problems whatsoever and no need to delete the fan and go with an electric fan we're good to go here🏁👍

It was just a very loud fan noise which actually in some cases is normal because when they car heats up the Bearings open up and expand and that allows the noise to get louder but then again some people debate that saying that it's a bad bad bearing and and this case I just had it replaced for peace of mind.
I checked all that there's no damage to my fan shroud or radiator all that was replaced as well.
Good point though these cars usually have to be bled a few times that's why the shop I brought it two hooked up an air evacuation system and did it right the first time problem solved👍🏁

No 'm not saying that at all. I just heard that in some cases on other vehicles when you start seeing antifreeze leaking from the thermostat housing or other areas it could be a sign of pre-mature water pump failure. On these cars the heart is vital and in this case that's the water pump so I didn't want to take a chance so for peace of mind I just replaced it all said and done.
