190 E Noisy Fan

[David Garrard]

I had some useful information returned regarding my previous query about a water leak, thank you.  On closer examination I found it to be the radiator which has now been replaced.  However in my quest to find the cause of that problem I noticed that the cooling fan behind the rad is very noisy, even when just freewheeling with the engine running.  I am told it needs replacing because the bearing has gone.  It doesn't bother me too much and I don't feel inclined to sheel out more cash just yet.  Any ideas on how I can silence it?

Hi David,

If the noise goes when you hold the fan. MAKE SURE THE ENGINE IS WELL BELOW 100DEGREES CENTIGRADE, and the noise goes. Then don't bother with it. The vast majority are like it and seems to cause no adverse affect.

Uncanny David! I noticed the same thing when I replaced my rad over the weekend, for a similar water leak mystery. Mercs are just SO consistent!

Takes a braver man than me to hold the fan with the engine running though - I like having fingers!

I get a bit of a rattling noise when mine is freewheeling as well, it cools the engine ok so sometimes its best to leave well alone i think!
