It sounds like my water pump is making a slight knocking noise, but is not leaking. I took the belt of and spun the water pump and it is the source of the noise. Does this mean it is bad a needs to be replaced, or is there a pulley or something that could be making the noise?

samaritrey

Does it have any play? Either way sounds like the pump is bad they don't have to leak to be bad. If the bolts are holding the pulley on I can't see a way for it to be bad unless it is bent or something. How many miles are on the car? Also they are cheap you can pickup a graf one for around $90 or a laso for around $135.

I have 144k miles. Bought it used with 124k. There is no play, but it does make a knocking or heavy clicking noise when you spin it. Sounds the same as what I hear with the motor running. The noise is most prominent at low RPMs and seems to go away as the motor revs higher -- or maybe I just can't hear it over the noise of the engine.

Going to replace the water pump and will do the idler and tensioner pullies while I am at it. Can anyone recommend an affordable place to order this stuff online?

Pelican Parts (a sponsor) has parts for every budget. They ship now.

Change the belt and thermostat too. Would not be a bad time to replace the coolant with the correct sauce.

Pelican has the parts from the original manufacturers which are just as good as from the dealer. They also have parts from aftermarket sellers if there are budget considerations.

Keep them honest by checking prices from RMEuropean and AutohousAZ.

Thanks. Pelican looks great. I am getting ready to purchase -- Saleri pump, Febi tensioner, Ina idler pulley, Vernet thermostat, MB blue antifreeze.

Does that look right?

glenrhoades

Forgot to mention that I changed the belt last month when I did the alternator.

glenrhoades

Ordered it. Thanks for the recommendation. I saved a bunch of money and the parts will be here in 2 days.

I might have gone with a Litens tensioner to avoid the possibility of a Chinese bearing in the Febi part. Who knows, it is already on the truck, could be a Litens in a Febi box.

glenrhoades

Will the Febi tensioner not perform well from the start or just not last as long?

samaritrey

The issue would probably be a longevity issue not an initial issue.

glenrhoades

Wow. Pelican sure is fast. I ordered the parts Tuesday at 4pm and they arrived Wednesday afternoon. Free shipping.

samaritrey

Where did they ship from? I have always wondered that? Keep us updated hope it all goes well.

my 2001 used to rattle like crazy at idle. replaced the pump and dampener arm and alls quiet.

glenrhoades

Installed everything yesterday and all seems quiet now. The old pump was not leaking, but the bearing seemed shot. You could barely turn it by hand and it was pretty loud.

samaritrey - The parts shipped from CA, which explains why I got them so fast. Still pretty impressive service.

atxmike - I am embarrassed to ask, but what is a dampener arm?

glenrhoades

I guess it didn't go so well. Everything seems to be running great, but the check engine light just came on (5 minutes into 1st drive after new water pump). I read the code and it says - "Manifold absolute pressure/barometric pressure circuit rang/performance input/turbine speed sensor A circuit".

What could I have done that caused this error?

samaritrey

whats the actual code it gave you? What have you done so far the water pump and the tensioner? Also curious did you have to thread a hole for something on the water pump?

glenrhoades

The code was P0106. I found a small vacuum that had broken off of a nipple when I was moving everything around. I reattached it and the CEL is not coming back on. However, I will need to replace part of that hose for a permanent fix.

I have installed the water pump and the tensioner. Yes, I had to use a tap to thread a couple holes on the water pump. I only threaded the first 1/4" and the screws seemed to self-tap the rest.

samaritrey

Do you remember what size the holes where that you had to tap? I have to do my water pump once the parts arrive.
Glad you fixed the CEL car should be good for another 100,000 miles.

glenrhoades

Thanks samaritrey. Sorry, but I do not recall what size I used. I just took the existing bolts and found a die that they would screw into properly. I then used the corresponding tap. I assume you could take the screw to the auto parts store to find the exact size of the bolt and then buy that tap.

It was kind of strange though -- I really only got the threads started about 1/8" to 1/4" deep at the most and was then able to screw the bolt in all the way and get the proper torque. It was like the metal allowed for self-tapping. ...or maybe there were threads in the holes that were just covered by paint or a thin layer of aluminum.

The bolts I am talking about are the ones pointed to in this photo I borrowed from another thread.

samaritrey

Thanks yeah i have heard that once you get it started it will self tap as it is softer than the bolt.
