Oil filter on 2008 Saturn Astra in inside of a canister that is located behind the radiator and a bit to the drivers side. A ONE-INCH socket is needed along with a ratchet, extension and universal joint to compensate for involved angle. Damage to the one-inch screw-on canister cap - I've seen a replacement available at eBay.

so unbolt it

It is located right on top of the canister, connected by rubber vacuum line to the intake manifold,

Bad sensor.

On a dry day take a garden hose and shoot water in any area that could leak and check and see if there is water in any of those areas. Also check under the car to see if there are holes or cracks that could leak. A rust spot will sometimes leak as well.

I find if you park on a grade different cars have a habit of doing that. Get some one to rock the car back and forth and keep working the lever as they do. I had mine stick just a week ago but I got it to release just by forcing the shifter. But don't do it hard enough to break it.

Make sure all new spark plug setting are set right. I bought a set and the car still would not run right so we found two plugs had been dropped and had to be reset. After resetting the car ran good.

If the motor comes on automatically when the car starts its possible a build up of ice in the winter could prevent it from operating and burn it out.

The fuse is #29 (accessory power outlets) in the engine compartment (under the hood) fuse center.

try a new bolt or your motor mount is bad

possible vacuum leak could be a vent control hose under the dash, transmission actuator hose, brake booster leak, manifold leak run the fault codes to find the sensor that is reporting the fault

-Disconnect negative battery terminal. -Take the airbox out of the way, easier to work on. -Remove the two long screws holding the alternator in place, I think it was with an e13 or 14 socket. -Jack up the car, and you can pivot the alternator out of the bracket, might need a screw driver, and disconnect the harness -After you got the alternator moved out of the way, there should be a 14mm, or 13mm nut holding the battery cable to the alternator. You can get it off with a long extension and ratchet. Then the hardest part, getting the alternator out the engine block, take the wheel off and try to get it to slide out the engine bay from the bottom. Its a hard task. I had to remove my motor mount and jack it up from the side to the exact position to get it enough wiggle room to clear everything. You could also try disconnecting the CV shaft if its really stubborn.

Hi , A PO420 code on all cars and trucks is a bank 1 cat failure and this code is determined by the ECM (Engine Control Module) by 2 sensors the Up stream O/2 sensor (otherwise known by some car manufactures as a Air/fuel sensor) and the down stream O/2 sensor. If you remove the Cat you will still receive a code due to the down stream O/2 is looking for certain gases which is produce only by the Cat as exhaust gases is passing through it. So yes there is no way around it if your getting a PO420 it is best to first take your car into a reputable shop to find out what is causing the cat to fail in the first place ( most likely due to O/2 sensor failure ) and possibly other things that could of failed leading to O/2 sensor failures along with the Cat. Hope this answers your question. Pat

look under the driver side dashboard as the flasher unit has to be heard by the driver and this is the usual place for flasher units or flasher cams or flasher relays. they go under different names but are the same thing.
