Water Pump Failure - ABA 2.0

Postby jreed1337 » Thu Feb 23, 2017 11:40 am

When a water pump fails, does it make horrendous noises?

My engine started making really gross, metal on metal types of noises this afternoon. It is throttle dependent. At idle it is there, but as the RPMS go up, the clanking/grinding sound gets worse.

There is definitely a coolant leak on the timing belt side of the engine, not significant, but a good drip after a few hours. No smoke, no apparent loss of power, no catastrophic coolant dump.

Oil level is good, and clean, no signs of coolant in the oil.

Coolant leaking + the noises (Bentley says excessive noise is a symptom) leads me to believe it is the pump.

Can't pull stuff apart until tomorrow afternoon, but hoping to get some insight from seasoned folks. This is my first ABA car.

Thanks!

It can,

do not run the motor, if the pump seizes the timing belt can break and other [shiz] can [frak] up.

I think on this motor the water pump is "external", not driven by the timing belt.

yah, it is driven by the accessory belt, not the timing belt.

When any bearing fails it'll make a horrendous noise. Before pulling the water pump, take off all the accessory belts and spin the pulley on each accessory. Listen for noise and feel for any grinding/resistance. Definitely have a new water-pump (as well as gaskets and thermostat, obviously) on-hand in case it is bad, since you're showing signs of leaks from that area.

ah that's a good idea. not sure why i didn't think of that. i'll remove the belts and spin the pulley's to see if there is any noticeable resistance/noise.

really appreciate the tip. ill do that prior to ordering parts, as the water pump is 180(60 core included) freaking dollars.

thanks man. :thumbup:

An ABA water pump should be $40, and another $12 for the rubber on metal gasket. Make sure it is one with a cast iron impeller, not plastic, not stamped steel.

all the repop ones are around 40-60 dollars.

Is the $180 price list? I'm positive somebody here can come up with an OE pump for less than that.

If anyone can, please do! Haha. ECS is the only place I can find online offering an OEM pump, not an aftermarket supplier. I can find them for 40-60 all day long.

Have yet to call a dealer though.
