Maybe never,But if you let your brake pads wear out to where the brakes are grinding,You may have to.
It has a permanent filer that is changed when the fuel pump is replaced.
A squeak in the steering of a 2004 Chevy Malibu is often caused by improper lubrication or worn components. Greasing the fittings will often reduce or eliminate the problem.
The 2003 Chevy Malibu does not have a timing belt. It has a chain which should last the life of the engine.
Recommended at 3,000 miles but your car can easily surpass 5,000 in most conditions. My 1999 Malibu is changed every 4500-5000 miles on name-brand filters and oil. No problems with good maintenance at 202,000 miles.
look in your owners manual but usually at 100,000 anymore.
when the pump was changed, maybe dirt fell in tank and the injectors are clogging up. run some good injector cleaner in fuel tank. and see if this helps, if it does add injector cleaner to tank at least once a month or more often. it will not hurt to use it more often.
The cam will normally last the life of the engine, if the engine is serviced regularly.
The engine oil should be changed every 3000-5000 miles
my '04 Chevy owners manual states 100k mi
It is located behind the engine down and close to the firewall. You can access it from the right side of the vehicle. I have used it often.
Brake discs or rotors need only be changed if they are scored or below minimum thickness. Pads will typically need to be changed about every 40,000 kms or so. Inspect for wear at least twice a year.
It depends on your driving style and the condition of the calipers. If you ride the brakes or otherwise drive in such a manner as to cause the brakes to overheat, the rotors will warp prematurely. If you are constantly in stop-and-go driving conditions you will wear out the brake pads and rotors much faster than someone who drives greater distances and seldom uses the brakes. I've seen some people who get little more than 20,000 miles from brakes and/or rotors. My last brake pads and rotors had over 70,000 miles when I changed them, but then, we drive long distances here.
