There is no "radiator cap" on the Alero. It has a pressurized recovery tank (overflow bottle) integrated into the cooling system. Unlike other cooling systems where you can add coolant to the coolant reservoir when the engine is hot as there is no pressure in the reservoir, these tanks are at full system pressure and must be allowed to cool down in order to check levels and/or add coolant. This is the only place in the system that allows for coolant input.

Check the codes. If it's the 3.4 vs then a good chance either a lower intake manifold gasket leaking or blown head gaskets as that is very common on that engine and is more noticeable in gear. Honestly hard to answer with specifics without more details including any codes stored.

Call GM dealer service and they should be able to give you an idea over the phone. Describe the EXACT problem to them.
This could be a bad keyswitch or a key gone bad. Could be bad switch down on steering coumn which keyswitch actuates. Hard to say. don-ohio

What is your question ? If you have aftermarket tires or struts, may need to put back what the manufacturer recommends.

As for the lights being on many GM products do that right after the key is off but if you open the driver's door they should go off. Not sure if that model is part of the ignition switch recall or not. Due to numerous ignition switch problems I would have the ignition switch replaced. The key cylinder IS NOT the switch. The key lock cylinder operates a rod that in turn moved the ignition switch to various positions. Battery must be disconnected and care taken not to deploy the airbag while the switch is replaced. I think I would go with a after market brand such as Delphi rather than another AC Delco factory switch.

The engine shutting off after starting may also be the ignition switch not moving to the RUN position properly. Before doing anything else I'd replace the ignition switch then go from there if the two problems are not cleared up.

Noises such as what you describe can be associated with wheel bearing, drive shaft or brakes.

The rattling noise could be a loose brake-backing plate and the buzzing noise caused by it touching a spinning brake rotor.

However, it could also be a worn drive shaft/constant velocity joint, which is the usual culprit.

The only real course of action you have is to give a mobile mechanic a call or take the car to a workshop and ask them to investigate -it will take just a matter of minutes.

Pull a plug wire , set the end close to the engine, crank it and watch for spark. No spark could be the cranks sensor, wires, ignition module , fuse, or PCM. Have the codes read. Could be the fuel pump too. I have had them die shortly after installs.

Rob, Your brakes will work, they just will not have abs function. You could take vehicle into a good shop and have scanned for codes, diagnosed and repair estimate.

quick way to see if a coil pack is firing with out using a thousand dollar analyzer is to use your twenty dollar timing light , just connect the power clamps as normal , but move the pick up to each branch pigtail wire to each plug , and ck to see if light flashes in a normal pattern , if it no flashes or don't flash in a pattern then that coil pack or spark plug is bad (id try the plugs first )

It may be a relay. Most likely under the hood. Swap it with another of the same and see if wipers work.
