Looking for input, Nissan says $1600.00 timing chain, my shop thinks its the alternator. What do you think?

Loosen the alternator belt and alternator. One of the bolts securing the alternator is very, very tight. Do not round off the nut, You will need a6 point wrench or socket, to remove nut. If the noise stops then it is the alternator. If not, then it the timing chain or something else.

 

I think wingnut has a good suggestion. With that in mind, go a step further and do the same with the power steering pump too.

 

Bolt on the power steering pump makes the both on the alternator seem easily. Will make you loose your religion. Do the alternator 1st. Good luck.

 

Had shop remove belts, definitely a timing chain noise.
Thanks for all the tips

 

Mrbizness1: What are they replacing for $1600?. Normally the chain guide falls and the tensioner does not have enough adjustment to take the slack out the chain, hence the timing chain rattle. Are they just replacing the broken chain guide and tensioner? Are they also replacing the chain? There is probably major wear on the camshaft tensioner shoes and they should also be replaced. Shoes are only about 3.00 each and if the dealership has the correct tool to replace the shoes without removing the camshafts then the labor to replace should be minor if thy did not include.

 

The dealers repair estimate isn't itemized. But I called a engine shop and was quoted $2200. With all new parts.

 

The dealers estimate isn't itemized, got a quote from a engine shop $2200. With new chain and other parts. The dealer wanted $1800. I love the car but not sure it's worth the investment.
