Hi folks, My son's 95 Taurus needed a water pump, which we replaced.
However, now after we started it up, we're hearing a sort of whirring,
almost like a clicking noise coming from either the alternator or power
steering unit(hard to tell where)...it was quite noticeable while we were
topping off the radiator and checking for leaks and everything after
starting up, and not as much now. It only happens now when the engine speed
increases.. not at idle. This wasn't happening before the pump went. Is it
possible that coolant damaged the alt. in some way?..(when the car
overheated)..or is there something else we might have done wrong on the pump
install? We bought a new pump, not a rebuilt, and it seems OK.. theres no
leaks or anything.
Any help or suggestions would be greatly appreciated.
Did you clean off all the pulleys good before reassembly? When i just
did my 93, the groves of the pulleys were embedded with crud. I very
carefully put a narrow object in them and carefully cleaned the crud
out of them. I was surprised how much crud was in them. Also check for
a loose piece of rubber on the serp belt slapping around. I have had
that happen once too.
You may try to remove the serp belt and carefully spin the pulleys.
Check the alternator, A/C Compressor, and PS pump for any unusual
Also, there is one more thing to carefully check. Check the tensioner
and idler wheel for looseness and even feel. I had some noise on my 93
last year that i thought was water pump. Wife called me one day and told
me the alt light came on and the car was hard to steer. Went down to
where the car was and looked under the hood. The serp belt was off.
Upon closer inspection, i noticed the fixed serp belt idler wheel
came off and apart. It drove its mount bolt though the window washer
tank. It was the bearing on the idler that was making the noise that i
thought was the water pump. Check to see that both idlers (if you have
two) spin freely and make no scraping noises.
Guess what! The pump vanes are rubbing the housing. Get a new gasket and
remove the belts. Pushing the shaft the direction of belt tension, then
the other, check for friction.. even then you may not be able to tell.
You probably will need to remove the pump and look for rub marks, if you
see them, push the pump the opposite way and make sure it doesnt rub after
you tighten bolts.
Yes..3.0L. Okay, I'll check out these suggestions. It's definitely not a
damaged belt that I can see. We'll take off the belt and check pump and
Is the pump vanes rubbing possibly from overtightening the bolts, or is it a
defect .. or what.
Thanks for responding guys... John
I have never seen that happen on a new pump. Now, on worn pumps
the bearing can wear eccentric and then the impeller rubs on the water pump
case. That i have seen many times. You have to be very careful with the smaller
bolts on the pump. Its not hard to break them off if
you over tighten them. I usually put a thin coat of RTV on the pump
and the gasket before i put it on.
Hey guys..actually this noise I was describing just suddenly stopped. So I'm
keeping an eye on it. It's not leaking coolant, so I guess the waterpump is
OK? Will have to watch it...and hope my son does too!!. Thanks for the tips
and advice. John
