I understand that the gasoline filter on a 2003 Pontiac Vibe is in the fuel tank, and seldom needs replacement
In the fuel tank on the pump.
No such animal . . . Vibe was released in 2003
If it's like my 2006 Vibe, the fuel filter and pump are one unit and it's located inside the gas tank.
It is attached to the top of the fuel pump assembly. It is the one with a three wire electrical plug.
The 1.8 liter four cylinder in a 2003 Pontiac Vibe has a timing CHAIN
If it is a Flex Fuel vehicle, YES. If not, NO.
The Pontiac Vibe's first model year was 2003. Because its model year was 2003, that means they were first produced and sold in mid-to-early 2002.
The one location to where the fuses for the air conditioner can be on a 2003 Pontiac Vibe. The fuses for the air conditioner will be in the fuse panel located in the engine compartment.
in the gas tank.
This is a link to the serpentine belt routing diagram that worked for my '04 Pontiac Vibe. As far as I know, this is the routing for all Pontiac vibe base and GT models. http://forums.genvibe.com/zerofile/1436belt.jpg
The Pontiac Vibe GT with the (1.8L 4cyl ) requires Premium Unleaded. The use of Regular Unleadedmay lead to predetonation or what is commonly called pinging. Although you may not be able to hear it, itmay be there. The Vibe's fuel/air managment system may be able to adjust for the regular fuel somewhat but at a cost of mileage and power. The engine requires Premium fuel, so burn Premium fuel. Burn Regular Unleaded and you risk engine damage.
