Engine noise question

I noticed yesterday a noise coming from my engine. I have not had time to try and pinpoint where the noise is coming from.

It sounds like if you threw some rocks in a dryer and let them tumble around. I listened the best I could and it sounds as if the noise is coming from around the alt. water pump area. i was thinking it might the water pump about to go out. The fluid level is fine and I did not notice any leaking around the pump.

I drove it today on the highway and in the city. The engine never ran hot and with the weather we have had here lalely I had to turn on the heat this morning and as usual it about ran me out of the Samurai. So there are no leaks, that I can tell and the engine is not runnong hot.

I also noticed I had no loss of power and the Samurai is actually running the best it ever has since I have owned it. Was cruising at 75 mph today and didn't even realize it.

On purpose I would have it in the wrong gear to see if it would not pull a hill but it did fine.

The only things I have done lately was change the oil and the oil filter. I also did the heater box clean out. Where you cut a hole in the side above the heater box and suck out all the crap in there. Could that have done anything?

Right now it is just an annoying noise but I don't want an annoying noise to turn in to a pain in the wallet.

If it is the water pump how hard are they to c [img]images/graemlins/confused.gif[/img] [img]images/graemlins/confused.gif[/img]hange? Again detailed instructions would be greatly appreciated.

Thanks for the advice and opinions.

Re: Engine noise question

First , check the fan clutch for wear or wobble, then move to the water pump and check it's bearings for wear . After that , it could be either the timing belt cover or the lower belt sprocket is loose and eating the end of the crank off .

Re: Engine noise question

Check the Alt bracket for cracks also. Hi frequency vibrations can destroy these. The cracks can
be rattleling
