The sensor is located on the front of the engine, under the intake manifold to the right. It's to the left of the oil filter housing above the starter. The electrical connector is clipped to the oil dipstick tube.

Hi, the low-pressure service port is on the line that goes from the firewall to the compressor. There should be a blue or black threaded cap on it. Just unscrew the cap and you're ready to add refrigerant.

depends on the motor. ECOTEC is on top at the front you have to unscrew the black cap it is a paper filter not a metal one. 2.2L and 2.4L the oil filter it at the back straight up past the half shaft(axel)

On the drivers side on top of the transmission, there is a red cap. Twist it off and you can fill it that way. You have to be careful though, because the only way to check the level is from underneath the car. There is no dipstick. Next to the oil drain plug, on the transmission, there is an 11mm bolt. This is the check plug. Run the vehicle to operating temperature and carefully remove the screw. You will know the transmission is full when the fluid dribbles out of the check plug.

there isnt one. there is a screw with a hex head on the rear of the transmission just above the transmission oil pan. when you take out the screw the oil will just start to drip out. to add trans fluid on the drivers side under the hood you will see a large black tube that comes off the engine. look just below that down into the engine toward the ground and you will see a red cap about 2 inches in diameter it says transmission fluid on it. you just unscrew it. you will need a long funnel or you will spill

the round thing on top of the rocker cover ,thats marked oil/oel/aceite

Almost every newer vehicle has the fuel filter in the top of the fuel tank. Good luck

Oil filter location for a 2007 Pontiac G6. First open and lift the front hood of car. Its some what right from center on the engine about 9 inches from the radiator. All you will see is a black cap with black plastic nut in the center. You will have to buy a special tool to attach to your socket wrench to remove the cap. Turn it counter clockwise to remove it. Inside is a filter attached to a plastic part and rubber o - ring. The filter is NOT enclosed in a metal casing. Remember how it is positioned as you take it out. Pull off the old filter. Remove the old o - ring. Place new o - ring in place. Place new filter on plastic part and place it back inside the engine. Make sure it is placed in the same way it came out. Screw on plastic cap by hand most of the way. The tighten with special tool and socket wrench clockwise, but not too tight. This is now complete. Now you can drain out the old oil from the oil pan underneath the car. Remove hex screw with long wrench for more leverage. One to 2 hours later place hex screw back in by hand and tighten with wrench. Now add about 4 1/2 quarts of 5W30 oil only. Check oil level on dip stick. Add more oil if necessary. Job complete!!!

This car does not have a auto trans dipstick, the level can only be checked by the dealer, this is a growing trend that started with most German cars, the filter is inside the trans pan and only needs changing every 60,000 miles.
