Hey, now that the snow is flying and the temperature is dropping my truck whistles in the morning. This only happens when the engine is cold, after about 5 minutes or so the noise stops. I have had my truck for about 3 years now and every year it has done this. It’s kind of getting annoying so I was wondering if I could fix this problem. I just replaced all my belts and the tension is correct. Does anybody else experience this with their 3.4 engines or Toyotas just don’t like the cold. thanks

 

bearings in the pulleys?

 

i hope it's not the bearings

 

My whistling was and whirring was from a bad power steering pump and pulley. Changed mine and whalah no more singing to me.

 

how much for the stering pump...and this only happend when it was cold out?

 

I wish i could teach my runner how to wistle and sing.

Actually i dont know how to fix it, but did you search?
