So this weekend i washed my motor and now when i start her up in the morning i get this whining sound coming from the engine bay..I'm sure its belt related, which goes away after 15-30 secs. Do you think i screwed something up? BTW, this is not my first time washing my car, i have done it 30+ in the past and this is the first...thanks..

Could be belt or a Pulley.

 

My Altanator does the same thing since i started washing it. Goes away after a few secs. My guess is surface rust in the altanator.

 

Maybe its squeaky clean hense causing it squeak. How many miles on belt mine broke at 50k

 

I have 95xxx miles on my car with the original belt...

 

change the belt. it's a great start
