how do you change a timing chain on a 98 altima?

Question

my timing chain broke and i need to know how to change it on my 1998 nissan altima

Answer 1

The '98 Nissan 2.4L has two timing chains, an upper and lower one. Here is a photo of the upper chain: http://www.rockauto.com/ref/BeckArnley/Detail.html?0241217.jpg

Both chains cost around $25 each. The chain likely broke with the engine running so you will need the repair manual to know how to install the chain and have the engine timing set correctly.

There is a Haynes repair manual available for the '98 Altima, part number 72015.

Answer 2

I forget if the 2.4 dohc was an interference engine. Take it to your mechanic and tell him your chain broke. It's an extensive job on any car but it may be just a chain, or you needing a new engine. If the chain broke on an interference engine, your valves may have made contact with your pistons resulting in bent valves, cracked valves, broken piston, etc.

HI! i'd first suggest that you buy the manual (chilton's or hayne's) from your local parts store and read it. it will have most of the info about that...it's a highly complicated procedure and worth too much (your engine) to type here...without being at your location to help you.

i take it to Gus, my mechanic
