Can you tell me more about this noise since I cannot hear the car
Is it a knock noise, tick, rattle?
OK, the story is this. For the past year or so when I start the engine in morning I heard flopping noise like some fray of a belt hitting something. It go away after the engine is warmed up. Then on New Year Eve, I change the coolant, in doing so I have to jack the car up to find the drip plug. After that, I started the engine and drove for grocery. All is fine. Then on yesterday, New Year's Day morning, I started the engine, and noise now metal grinding against metal.
constant noise, hot or cold?
the engine temp is ok since the coolant change, not running hot?
I never drive car out of my garage because of the noise. I let the engine run for 5 mins and the noise did not go away, I turned the engine off. The temp seemed to be ok, but I have to double check.
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
My hearing tell me that the noise is front the front of the motor, like around fan belt or pulleys.
OK, the first thing I would do is..remove the belt, then start the car and see if the noise is gone
By the way what is the 'R' in Outback R L.L. Bean Edition stand for.
you will need a 14MM wrench to pull back the tensioner pulley to release the belt
That is the hard part, how do I remove the belt.
And put it back on.
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
get the pics?
also, these multi groove belt can make a racket if you have spiller coolant on it
I got the pics, I have to look at them carefully to differentiate the bolt from the golt.
got me there
Any questions on the pics or procedure?
I know what a bolt look like but not golt.
I know what a bolt look like but not a golt
Golt was a typo
Thanks, I now get the sense of humour
If the noise is gone with the belt off, that mean I have to replace the pulleys, and is that something I can do?
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
That sounds complicate to me. Are there any possible cause of the noise, like the bearings, and is it save to drive shorten distances with those noises.
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
I have jacked up the car the locate the coolant drain plug, could I have messed it up by jacking up properly? I have located the jacket up arrow under the car.
I mean by "not" jacking up properly
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
I am sure I did not jack up on the oil pan. And you are right the noise would have been there right after the coolant job. Because my wife blamed for that.
I now feel less guilty, but still the noise came the next morning after I thought I have done a good thing to the car.
check the pulleys and the belt, as I said, sometimes the belt will get real noisey if coolant gets on it.
So, the coolant, even if I have not fill up to proper level, would not be an issue.
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
I am not quiet sure if any coolant have spilled onto the belt. I will try to start the engine again. And, can I ask you some more questions to-morrow.
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
OK, before signing out for to-night, 2 more questions: 1. Does my car have a timming belt or chain and do they need to be replaced and 2. What is the reasonble cost for diagnosing the noise problem and replacing the pulleys, if that was the cause.
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.
So the tensioner and idler pulleys are general issues with the 6-cylinder OBs. The same with 4-cylinder OBs?
they are issues on the 6 cylinders but a different configuration on the 4 cylinders..not an issue on them.
Thanks, will have follow up questions. Signing out and good night.
ok, good night
