Has anyone ever had a water pump make a lot of noise in its old age? I've bought a replacement 2VZ engine for the beast, but it's won't be in the car until spring. When I fire-up the car now (with 380,000km on it), in the cold, I'm hearing a new and unsettling sound. Very difficult to describe, like an intermittent humming/droning/metal-on-metal sound from the general area of the pulleys. Goes away once warmed-up (from 25 below freezing).

Sound familiar to anyone?

Sounds like the WP bearing that went bad in my 95 Corolla at about 85k miles.

For 5k miles, it made the noise, never leaked, and I simply replaced the pump with a new Toyota unit.

Thanks for confirming my fears...there really wasn't anything else it could be, but I like second opinions...

Cheers!

I is really cold were I live (northern wisconsin), and my '88 3S-FE with 136,000 is making the same sound when it is really cold (10 deg and colder). It is very loud, coming from the pulley area, there is a lot of depth to it, almost internal sounding. Then with in 30 sec. to a minute it gets more quiet, and goes away. It is a roaring growning sound kind of a err, errrr, er, ohh, oh, ah, and then gone. I wasn't sure what this was, but that makes sense that is could be the water pump.

Yeah, mine didn't start making the sound until the past two weeks (it's been -30 Celsius most nights/mornings). The block heater on one bank of a V6 can't really keep everything warm, and two heaters would be overkill...

If i were gonna keep that engine i'd just change the timing belt and change all the other stuff then. Idlers and water pump too. And maybe a valve job if the compression were low.
I'm guessing that you probably have no plans to tear into it with a new engine waiting and all, so maybe i'd dump in some "water pump lubricant" in the cooling system for now.

^^^ Good thinking, marc780. I can't get the new block in until it warms-up in a few weeks (I hope), so prolonguing the life of this one is a good idea. I had completely forgotten about the pump lubricants you can buy...thanks. :D
