Hello

Can you tell me more about this noise since I cannot hear the car

Hi

Is it a knock noise, tick, rattle?

constant noise, hot or cold?

the engine temp is ok since the coolant change, not running hot?

Ok, can you tell if the noise is originating from the front of the motor, like around the fan belt or pulleys? These 6cylinders are known for there idler and tensioner pulleys making a bad grinding noise..just before either of them fail

OK, the first thing I would do is..remove the belt, then start the car and see if the noise is gone

you will need a 14MM wrench to pull back the tensioner pulley to release the belt

if the noise is gone , turn off the car and inspect and spin the pulleys to see which one is bad...I will attach pics that will show you how to remove the belt..it's simple and the belt diagram so you know how to reinstall the belt

I am also attaching a pic of the pulleys (circled) so you know which ones to inspect

Now, if the noise is still there with the belt off, then you have another issue, could be exhaust shields noisey or maybe internal motor problems but I would pull that belt off first

If you look in the pic, you put a 14mm wrench or even a socket on a wratchet on the front golt of the tensioner, then just move the spring loaded tensioner down to release the belt tension, then while holding the tension on the pulley, pull off the belt

bolt..not golt

get the pics?

also, these multi groove belt can make a racket if you have spiller coolant on it

got me there

Any questions on the pics or procedure?

Golt was a typo

meant bolt

If the noise is gone then inspect and spin each pulley to find out which one is noisey and probably will feel loose as well, if it's the idler pulley (in the diagram) that one is easy, the tensioner pulley is harder and requires removing the alternator and moving the Power Steering pump as well to replace the pulley/tensioner assembly

If it is a pulley, I would recommend not driving it , if the pulley fails, it will cause the belt to fall off, you will not have power steering, or your alternator supplying power.

the bearings in the pulleys wear out

only if you jacked up the car on the oil pan

Also, the noise would have been there right after you did the job..you said you drove it to the store and it was fine.

So, I would check the pulleys before any other diagnostics

check the pulleys and the belt, as I said, sometimes the belt will get real noisey if coolant gets on it.

not as long as the car did not overheat, these cars are hard to get the air out of the system, so if you drove the car and it overheated bad, then you very well could have internal issues, but you said it did not run hot, so you should be fine

sure, even after the accept you can come back to your question which will be in Q&A format and post..I will get an e mail alert that you have posted and will come to the question to respond

Your car has a chain, no replacement interval. To diagnose the noise should onmly cost 1.0hrs labor unless it's internal then it can cost a lot more. to replace the idler pulley would cost another 1.0 hrs labor. To replace the tensioner pulley, that can cost between 2.0 - 2.5 hrs. labor. the pulleys are about $80.00 for the Idler pulley and $225.00 for the tensioner pulley assembly.

they are issues on the 6 cylinders but a different configuration on the 4 cylinders..not an issue on them.

ok, good night
