anyone else experience this?
Brand new from FORD waterpump. The job went as easy as could be...Perfect, no issues -thanks Maintain!!!. ran it for 1500 miles...Perfect.
one day i heard what sounds like a fan belt howl....Nope not the belt. removed it and started spinning pulleys. When i spin the waterpump/fan pulley, i hear what sounds like friction but, it doesn't sound metalic (bearings). It sounds like tight rubber seals or something.
If I spin the fan clutch by itself (by spinning the fan with the belt installed, truck off...lol, obviously), no noise.
i tried a little PB blaster on the backside of the pulley...soaked it pretty good...no diffference.
once the truck goes over 1500 rmp or so, the sound is apparent. At idle, it can barely be heard and is inconsistent....sometimes it's not there at all, sometimes it's intermittent but, it's always constant if the trucks been over 1500 rpm.
wierd i tell ya...
my coolant is a little overfull -1/2" above the line...can't imagine that being a problem...
maybe i have air trapped in there somehow?
i really don't want to do this waterpump again.
open for suggestions.
