View Full Version : 2003 Sunfire timing chain

Any idea if a person needs any fancy tools1 to change the timing chain on this 4 cylinder. I'd just be doing it in my garage. Put it up high on blocks\jackstands and go to it[36] Its our daily driver so I wonder how long it would take. I have air tools, etc...

Man, its the best cheapest fastest economy car I've driven[36] Its the GT model with the 2.4 Liter. I think the smaller engine is a 2.2 Liter. I think GM said about $800 to do it. If I pick up a haynes manual from Lordco would that be good enough or are you talking about a different book Growly?:confused0006: I'd rather make a few bucks to pay the garage to do it;) .

Looks like the top motor mount needs to come out. Waiting to get a manual. Thinking it could be done in a shop in one day rather a week in my garage when I have time. Wife needs the car. Still runs A-1 for now!

The engine doesn't have to come out, but they are really fun to do. Also do the water pump while your at it, it is driven by the chain. They do call for a cam holding tool, but I've never used one. I'ld guess parts to do the job wright, would be about $500, chain, gears, guides, tensioner, waterpump, and possibly exhaust maniflold gasket. Oh ya and the thermostat is a whole bunch easier to do when the waterpump is out.
