I posted this elsewhere, but I wanted to see if anyone else has had this problem. It started soon after I bought the truck (06 DC Tundra), and has gotten worse, the dealer does not know how to fix it. The noise is always there, it never goes away. Any ideas?

lilwilly, I gotta ask is the truck actuallt running? If so I would go with waterpump, possibly the bearing inside of it....How many miles on the truck? Good luck, CSM-H

Is it the TSB for the Dampner/A/C pulley. Print the TSB off the web here and show it to them and have them give that a shot

The truck is actually running, and it has 2200 miles on it. I thought it sounded like a water pump also. On the first visit the dealer aligned the belt, the second visit they performed the TSB o nthe dampener and AC pulley. Still no luck. Now they do not know what to do. Thanks for the advice. I like the truck, but not happy with the noise.

I would ask for a free rental and dump it in his lap and then he might be concerned a bit more. Dealerships should take care of you not blow you off!! That was a terrible noise and good luck!! do you keep block heater hooked up or do you not have to fool with that type of thing where you are?

I agree! If the noise gets progressively louder as you rev up the motor I am going to have to go along with these guys and says possibly a bad water pump. Which as we all know, requires removing the timing cover and everything to replace. If they fix that and it does not solve the problem, I would DEMAND getting a replacement vehicle

I would say you're in line for the lemon law if the dealer can't fix it. :tu:

Agree. With 2200 miles leave it in their lap until repaired with them paying for the rental. Mine has a similar noise but not nearly as loud as yours. Mine is out of warranty to once they fix it please post the problem. Drop it off.

You can email your state Attorney General with a complaint. That usually get things going in a fast way. I would also get in touch with the regional manager and tell him of your problem, and that you need a rental car until your warranted truck is fixed. Maybe tell him you've been told to go to the Atty Gen, but wanted to give him a shot first.

Thanks for the replies. I spoke with the General Manager of the dealership and he vowed to make it right. If the regional tech that's flying into town next Tuesday can't fix it, he will put me in a new truck. They don't have any 06's so it would be an 07. I feel much better knowing the dealer has stepped up and promised to fix it or replace it. I really want my truck fixed, as I like the 06 a little better than the 07, but either way it will get resolved. If they fix it I will post the outcome - thanks again!

lilwilly,
You can easily determine if it's the water pump by briefly running the engine with the serpentine belt removed. Since the timing belt runs the water pump, the removal of the serp belt will isolate the water pump from all of the accessories. Don't worry, this will not damage your vehicle as long as you don't drive it around town in that condition. I've done this myself.

If you really want to keep your 06, I highly recommend that you perform this test before taking it back to the dealer. That way you will positively know if it's the water pump or something related to the serpentine belt.

There are many posts on TS describing how to remove it. It's easy to do once you figure it out and have a long handled wrench/breaker bar to compress the tension pulley.

Let us know what happens. Good luck.

Picasso,

Thanks for the advice. I removed the belt an ran it last night, the noise went away, but I wasn't aware that the timing belt runs the water pump. I also put a wrench on the tensioner pulley and ran the engine while putting more tension on the belt, thinking it might be slipping. The noise got worse with more belt tension. Then we releived tension as it was running and it starting to get better, but did not go away. We had to stop as we were afraid the belt was going to come off.

Picasso,

OK. The sound is NOT related to the water pump or anything associated with the timing belt. Excellent.

I also put a wrench on the tensioner pulley and ran the engine while putting more tension on the belt, thinking it might be slipping. The noise got worse with more belt tension. Then we releived tension as it was running and it starting to get better, but did not go away. We had to stop as we were afraid the belt was going to come off.
Wow. That sounds very dangerous, but it provided a lot of good info. I take it that you had to remove the fan in order to play with the tensioner with the engine running. If so, you have also removed the fan as being the likely source of the sound.

Now that you have isolated the sound to the serpentine belt, there is an easy test you can do to find the culprit. Get a length of vacuum hose, any kind of hose, and use it like an automotive stethoscope. Put one end to your ear while placing the other end near the accessories driven by the belt. Don't forget the top pulley and the tensioner pulley. You might want to tape the hose to something rigid so that you can easily direct the end without having to stick your whole arm down the front of the engine.

The sound could be caused by a bad bearing or just an accessory needing some alignment with the serp belt. Once you find out where the sound is coming from, you can provide that info to the dealer and let them fix it under warranty.

Be careful and keep us posted.

i'm gonna go out on a limb here and rule out a/c clutch bearing. you would have noticed that cycling on and off. could still be the a/c outer bearing, though.

p/s bearing may change pitch when you turn the wheel?

alternator???

hmmm... what's left? tensioner pulley?

belt dragging on something?

since it get's worse with more tension, that sounds like a bearing with some debris in it dragging on the race. i would also guess from the long loping cycle, that it's something with a fairly large pulley.

so, my money's on either the power steering pump or the tensioner pulley.

if you don't have a piece of hose, use a long screw driver or something solid. put your ear on one end, touch the other end to each area and listen. works similarly.

keep us posted! inquiring minds want to know!

on a side note, one time i built up a 302 ford engine and had to fabricate a bracket - alternator i think. anyway, long story short, i found a hole already tapped in the block, but the bolt i used was a tad too long. on first start up, made a horrible noise, kind of like what you're hearing. took me a while to find it, but that long bolt was dragging on something internally. easy to fix, no damage done once figured out.....

I just got my truck back after three days at the dealer. They gave me an 07 Tundra as a loaner, which was nice. They had an engineer fly up from Portland to work on my truck. So far it seems fixed - no noise. They told me they adjusted the power steering pump pulley, they said it was sticking out too far. I did not get the official paperwork as they were still working on it. I like the 07, but I'm glad to have my truck back. Thanks for all of your help and advice.

I guess I spoke too soon, the noise is back and getting worse. I'm going to give the dealer one more shot. If they can't fix it, I'm not sure what to do. The 07 DC is smaller than my 06, and the crew max is big but has a small bed and most likely needs the 5.7 to tow anything. I like the dimensions on the 06 DC and the fuel economy of the 4.7. So my choice is a new Tundra, or maybe a new Tacoma. That is if the dealer works with my to get out of this truck like they saud they would. If not I my look at a Dodge or Ford. I like the Tundra and I think they are good trucks, but I must be the one in a thousand that got a problem truck.
