To reset the change oil light, turn the ignition key to the "On" position without starting the engine. Within five seconds, press the accelerator pedal to the floor three times. The light should flash and then go out.
The recommended tire pressure for the 2004 Pontiac Montana is typically 35 PSI for both front and rear tires. Always check the sticker on the driver's side door for confirmation.
Start by checking the refrigerant level, ensuring it's sufficient. Next, inspect the fuses and relays related to the AC system. If those are fine, look at the compressor clutch and see if it engages when the AC is turned on.
First, check the battery terminals for corrosion and ensure they are tightly connected. If the battery is fine, test the starter and alternator. A weak starter or failing alternator could be the issue.
Open the hood and locate the headlight assembly. Remove the two bolts securing the assembly and pull it forward. Disconnect the electrical connector and twist the bulb socket counterclockwise to remove it. Replace the bulb and reassemble in reverse order.
Common causes include low coolant level, a faulty thermostat, a blocked radiator, or a failing water pump. Check these components and ensure the cooling system is free of leaks.
Warm up the vehicle by driving it for a few miles. Park on a level surface and keep the engine running. Open the hood, locate the transmission dipstick, remove it, and wipe it clean. Reinsert and remove it again to check the fluid level. It should be within the marked area.
The recommended engine oil for a 2004 Pontiac Montana is 5W-30. Always refer to the owner's manual for any updates based on your specific driving conditions.
Check the sunroof drains for clogs, which can be cleared with compressed air or a flexible wire. Inspect the seals around the sunroof and replace them if they are worn or damaged.
Locate the serpentine belt tensioner and use a wrench to rotate it, relieving tension on the belt. Remove the belt from the pulleys. Position the new belt according to the diagram on the radiator support, and release the tensioner to secure it.
