Replacement of chain belt oa altima 2004

Remove cams, install air hose adapter into each cylinder one at a time and use compressed air to test cylinder. Bent valve or holes in pistons will be very obvious.

This was a very good diagram to help me and my uncle put on the serpentine belt after replacing the alternator

You need to know if your car engines is a interference motor first !! An interference motor is when the timing belt breaks while you are driving and the valves stop but the piston heads keep going up into the valves and destroys them and the heads that hit them. Usually for a mechanic will charge you about 50 or 60 dollars an hour so he has the book that tells him how long it will take to replace the timing belt so go call several of them they will say the same thing trust me I have called many of them in the past myself.

If it broke while being started you more than likely have very little piston or valve damage even if it is an interference engine which I am not sure of. I have no idea what they mean by belt rollers when talking about the cam chain. It is a chain not a belt. You should be able to remove all spark plugs then spin the engine over with the starter an check the compression. If the compression is good then you more than likely have no serious damage. At that point all you can do is replace the cam chain and see what you then have. Once you get this fixed, sell the car.

If its a belt should be at 60000 on the safe side chain at 100000

I think it has a chain. look where the timing chain/ belt should be. if there is a large plastic cover, it has a belt, it its a aluminum cover, it has a chain. there is no replacement interval on a chain.

Hi,
Here is the belt routine diagram

Hope this helps
Thanks

altimas have timing chains no belt replacement needed (both have chains 2.5 and 3.5 engines)
