Dude you are on crack! My '03 Malibu LS SIPS gas! Other friends with the base model and older Malibus say the same thing!
The 2003 Chevrolet Malibu runs on regular unleaded.
5w-30 is recommended but you could use 10w-30.
It calls for dex-cool.
does a 2003 chev Malibu have a fuel pump reset switch / No, Gm does not use inertia/reset switches.
No, that's not normal.
That would be a relay, not a fuse.
Use penetrating oil and correct size wrench.
YES--now days 134a coolant is used in all systems.
87 octane is good for 3.1 but if ya want to use a different octane it wont hurt.
Use what the manual tells you....regular gas.
The 2003 Chevy Malibu takes a 22" drivers side and a 19" passenger side. When buying windshield wiper blades be sure to always use the application guide book at the store or now-a-days you can google 'lookup wiper size'.
At present there is a class action suit against Dexcool. So use the green antifreeze.
