Chirping bird when hot

[butternut325]

My chirp just happens when its real hot or the car is idling and temperature is normal.

Me too. Only when nicely on temperature.

Let me know when you replaced the crank pulley!

The car is there right now - I haven't heard anything from them yet..

Got the car back. Chirping is gone.


They said the belt was compromised with oil. (Don't know how it got there?)

Changed the belt. Sound is gone for now.

Man! Hope it stays gone. I changed my belt with a aftermarket and genuine one but it did not work.

 

[Ricky318i]

I hope so too because they've changed everything except for the vibration dampener and I hoped they would since it is so expensive.

Keep us updated please?

Today i sprayed some oil on my waterpump pulley and the sound immediately dissapeard??? So the belt is the culprit or the waterpump pulley is skew?

 

[grim101]

Changed the belt and when warm the chirp sound is back? Any advice??

Did you replace the water-pump for a second time ?

In your first post you listed the water-pump as being changed and then again yesterday ?

Secondly - R1500 for a pump is too cheap;

The pump from the agents (the only one you should use) is R1800, you will loose a fair amount of coolant probably half - so you will need two liters of coolant R80 odd per liter with two liters of distilled water.

Add 3 hours of labour @ R700 per hour - R4000 odd.

The logic of agents only parts is seriously flawed, Bmw do not manufacture parts, they are made by the likes of Behr, Lembforder , Bosch ect which are sold at places such as goldwagen, imcommex ect who sell them for half the price of bmw in most cases.

+1 to the power of 1000 :thumbs:

Just my experience on this one,it happened to me on more than one of the cars I owned, it was either a belt that was too tight or too loose. Anotner time it was a belt rubbing against something in the engine bay when it warmed up.

Also, my question here is: did you do any of the work yourself or do you just believe everything the mechanic tells you? Did the mechanic give you the old parts which were replaced?

I ran the car and took a spanner and pulled and pushed the tensioner and it only went silent when it almost slips when releasing the tension.

What about belt dressing?

 

[Charlie Brown]

What belt is it ?

If it's a Gatorback change it, they stretch I have found

Check your accessory belt as well. That was my culrprit. Replaced serpentine first. Sound stayed. Then changed the accessory belt and all was perfect.

Both belts are new. Sprayed belt dressing just now. Will test it later.

 

[grim101]

Chirp still there. When I spray the belt wet there is no sound untill it dries off again.

Are you sure the correct belts where fitted? If so then I would suggest replacing tensioner as it seems the belt is loose

I replaced my standerd alternator pulley with a overrun/clutch pulley and now the sound is gone. Just chirps when you start it.
