Could it be the water pump?
At random times my XJ will have what can be best described as a loud "growling" coming form under the hood. When this happens the temp spikes from 190 to 220ish. It happens on a cold and warm motor just the same.
The rumbling/growling is pretty loud and causes a vibration that can definitely be felt in the cab.
This seems to be random and lasts about 20 seconds each time. Then it just goes away and the temp drops back to normal...
I'm thinking the bearing in water pump is the culprit... Prob need to get a mechanics stethoscope on it but just havent picked one up yet.
Thoughts?
Thanks Fellas!

could be pump or belt or any of the other components running off the belt. The vibration parts points me to look at the mechanical fan.
