There is not a 2.3. It is a 2.8. The oil filter is on the top drivers side about the middle of the engine. There is a "cover" with a hex bolt in the center to remove it. The cts is a very easy oil change.
Please give me the location of the Oil Filter and Oil Plug on a 2007 Cadillac CTS 2.8L Engine.
The Location of the oil filter depends on which engine you have in your CTS. the 3.2 engine the oil filter is located on the bottom of the engine to the left of the oil pan. It is not a screw on type filter it is a canister filter. You will have to unscrew the lid to gain access to the oil filter. On the 3.6 Engine the oil filter is also a canister filter but it is located on the top side of the engine. On the drivers side around the center of the engine cover. It will take a 15/16 socket to remove the lid.
2009 Cadillac CTS Sedan - Rear Wheel Drive - 6.2 liter, 8 cylinder (Premium Gas) - Motor Oil Capacity: 6.0 Quarts with Oil Filter Change -
In front of the motor
At the bottom of the engine.
No
on the top drivers side of the engine by the oil dipstick 7/8 socket I believe
On the 2.8 and 3.6 liter engines the filter is located on top of the engine, next to the fill cap on the drivers side. The 6 liter engine filter is next to the oil pan on the passenger side.
The oil cooler on a 2003 CTS is located on top of the engine block between the heads but below the intake manifold. It is not visible with the intake manifold in place but you can see the inlet and outlet lines that run from the side of the engine where the oil filter adapter is mounted around to the back of the engine.
You can't go wrong with the original equipment GM filter.
