Cracking sound
I am getting a cracking sound coming from front of motor. At idle speed it comes and goes every couple seconds. Sounds like plastic cracking or old ball bearing cracking. I have narrowed it down to around water pump area. When rpm increased noise is not as noticible. Belt is new. A/c and air pump removed. Tensioner is solid, no movement and belt tension is ok.
Could it be the water pump?
Has anyone experienced this noise?
Thanks

They are all smooth except the water pump pulley. It does not wobble and does not leak but it does feel a little rough. Think this is where the cracking sound is coming from? Ok to drive like this until I can get a new one?

The crackling your talking about is most likely the bearings going bad in one of your accessories or the water pump, sometimes just spinning them by hand won't reveal which one is making the noise.
Hook everything back up , start the car , if you can't tell which one is making the noise, then use a big long screwdriver to touch each accessory while holding the other end to your ear, then you should be able to hear which one is crackling. This is the way we always used to check for any unusual sounds in a motor...Just be careful you don't get you hair caught in the belt or you will have problems....

Tried that with a friends stesthescope. All pulleys seem smooth except for water pump which had the cracking sound. I just can't change right now and was wondering if anyone else had this problem and if it might be ok to drive for a few miles?

I wouldn't take any long trips with it going bad, but staying close to home shouldn't be a problem.. Alot of times they start leaking from the weep hole on the bottom before they go completely out..Replacing takes about 2 to 3 hours....WW

I would fix that as soon as humanly possible if you need this car running, IOW as your main source of transport. Overheating will cause many vastly more expensive problems in a very short time.
