You can replace a timing chain on a 2002 Pontiac Sunfire by visiting a local mechanic and having him take care of it for you. This is a tricky part to change yourself.
All 2002 Sunfires, 2.2 and 2.4, had timing chains
The 2.2 litre four cylinder engine in a 2002 Pontiac Grand Am has a timing CHAIN
Both engines that are available in the sunfire are electrically controlled timing. You do not need to do anything to sett the timing, the ECM does all the work.
The GM 3.4 litre V6 engine has a timing CHAIN
The 3.1 liter V6 engine in a 2002 Pontiac Grand Prix has a timing CHAIN
Yes. A chain, actually.
Where is the fuel idle control valve for a 2002 Pontiac Sunfire
Yes, you could. Is it a good idea? Probably not. If the tensioner is worn so must be the chain.
no
The side of the driver's door on my 2002 Pontiac sunfire is a little hard to read, but I believe it says 30 PSI.
The 2002 Pontiac sunfire does not have a cabin filter. The air flows freely either in fresh air or recirculation modes.
