Hi all,
I have a 98 Sport with 4.0 SOHC motor. It has 91K miles now and has just developed an odd random clattering noise. I feel like I should already know what this noise is ... seems old school, like I had a 70s-era car that did the same thing.
It does not vary with engine speed, and does not change if the A/C is turned on or off. Cold or warmed up. no difference.
You can hear it better if you are under the radiator than above the motor.
It does not seem to be coming from PS, AC, idler pulleys, valve covers, or engine itself. I was using a large dowel rod as a stethescope to try to pinpoint this. Could not get to the water pump due to the belt.
The fan does not seem to be loose or wobbly. Do fan clutches get noisy as they age?
How about AC clutches?
A bit stumped here .... seems to be running fine. I would think that increased engine speed would increase it or make it go away, but no real change.
