4.0L motor has been consuming coolant for a while (had to top off the reservoir once every 1-2 months).. I didn't think anything of it until today, when my temp gauge started fluctuating considerably between two positions, both below 210.. It also started spewing antifreeze from around the waterpump area. I'm planning to pull the fan to see better what's going on tomorrow. Anything I should look for?

After a little reading, I've found that the water pump has a weep hole that'll drip coolant upon pump shaft failure... Bad water pumps will also sometimes cause a mild howl audible at the front of the engine.. Sounds like what's going on..
