Hello all, today my c43 started making this noise. Is it a loose belt? It's the worst at start up but stops then randomly comes back during driving for short times. I attached the link. I'm not mechanically inclined at all so hopefully i don't sound stupid haha.

just remove the belt and run it for like 10 seconds (you can also inspect the belt while it is off). its very easy to do, probably easier than you think. youtube it. the belt isnt that expensive either.

Birdie, birdie, where are you hiding?

mickey13

you might as well replace the tensioner while your there. another cheap part

mickey13

LOL

cheap part? It cost me nearly as much as a new water pump. Around $380 equivalent. Water pump was $403 but reduced to $350 as it was a factory reconditioned unit. All told I spent around $1000 just on parts to repair the oil leaks, squeaks and preventive maintenance.

To the OP: I would change the serpentine belt and if you want to do a simple preventive job, replace the idler pulley above the water pump and to the left of the thermostat. You can find plenty of DIY videos on YouTube for this job
Sorry for the dirty engine but I hadn't cleaned it yet, and I did find the oil leak which has been bugging me for 2 years now! It came from the lower side of the oil pressure test port (see the rectangular top caked in oily crud just above the tensioner)

what do factory refurbish on the 2nd hand wasser pumpe?
do they only change the bearing and then spray the pumpe with spray paint making wasser pumpe look like neu then selling the pig in da poke for $350?
this is good biniz for MB making monie

DRBC43AMG

Yeah, probably change bearing, axle, rotor and pulley. Plus a nice polish. I'm 100% for sustainable products when possible. Look at the photo below. It looks brand new to me...

To the OP:
I would also investigate a possible bearing on it's way out in the alternator. They do also die...

mickey13

i paid $63 for a new water pump and $121 for a new belt tensioner, didnt buy from the dealer though. got it through autohauz

also paid $13 for the idler pulley

DRBC43AMG

Guess that's great news for people living out of Switzerland

Would a bad alternator bearing cause my car not to start when I don't drive it for two days? Cause that would make sense then

i know you are getting deep discounts on chocolate and watches... plus do i even have to mention women in swissland? i happen to know,,, super hot!

mickey13

possibly... i would say get your battery/alternator tested. they do it here at all the local parts stores for free. the other thing i would suggest is you check the codes on your car with sds or some other system that reads mb ecu.

Okay thank you all for your help this really is a great community of people

Definitely not belt. Bearing in a pulley somewhere like others said. Alternator, tensioner, etc. Take the belt off and turn them by hand.

run it with the ac off to see if it goes away. Pray it's not the ac compressor.

mickey13

well if it is...

bought a rebuilt compressor from miami compressor for $118. they have a website and also sometimes sell on ebay. these compressors do not come with oil so make sure you get it done somewhere professional and bring them the 8/16 ounces of compressor oil (cant remember if 8 or 16, but it comes in a small container but you really have to make sure you get the right oil- - the compressor should be marked on what kind it uses or you call miami compressor and they will tell you - autopart store tried to sell me the wrong kind)


my AC is working really great now

KJI3jflarryfe93

it's the swedish sin you think about not swiss women

DRBC43AMG

Heidis are better tasting than Abbas. Have a more flower and mountain grass taste. Mmmmmm....

KJI3jflarryfe93

what i meant was Mickey13 from da Bronx maybe mixed up the blondes by refering to Swedish sin which has the world wide rep to be easy

I don't give **** about ABBA, what is dat?

natural flavour from mountain water and grass do give a better taste.
blonde Heidi with pigtails must be very fun to play with in the hea on the 2nd floor up in the barn loft

mickey13

lol no i didnt mix them up. Zurich is full full full of beautiful sexy women at all the clubs dancing all night long. LOL

DRBC43AMG

I'm too old for that kind of entertainement...

KJI3jflarryfe93

in another thread you ask me if I use blue pills.
my reply was 100% all N/A

I thought you had a stash full of blue smurfs for entertainment und pleasure

DRBC43AMG

Nah, don't need them and even if there is some lost power, the torque is still there

Fark a duck... They saw you commin...

The OEM water pump is an SKF, and i only paid $180 AUD for a brand new one in Australia, and couldve got it online for $154 AUD if i wanted to wait a couple days.

The water pump will make squeaky noises when the bushings are rooted, and it should be replaced. When the bushes wear out, the impeller will come into contact with the housing, and it will cause a bit of drag on the belt being so stiff to turn.

The idler pulley cant really be swapped out with the radiator in place unless you remove the water pump. You could cut the bolt and use a piece of threaded rod with a nut on the end, but itll look obvious.

The tensioner is probably fine, just replace the pulley unless you know the tensioner has had the dick. I had almost 280,000klms on my W210 E55 and original tensioner was still perfectly fine.
