Top 20 1995 Oldsmobile Aurora - Page 7 Questions & Answers

Have you checked your ignition relay? Also check the ground for proper grounding. If the ground is not correct then you will not start. You can also try running extra ground wire from the starter to the frame of the vehicle sometimes that will also cure the issue. I would check the fuse and relay first before anything else though.

FUEL SENDING UNIT there is an access hole under the carpet in the back right corner of the trunk. access this compartment and have someone else turn the key but not all the way to start the engine to check if the unit is operational it is easy to tell because you will hear it. humming you will probably need to replace it- here and here are detail instructions on replacing a pump similar to yours.
Best of luck

It may be a bad radiator cap or the top radiator hose is loose or worn out. Water may be coming out as steam which is difficult to trace. If you have white smoke at the back or check your engine oil for water content, your head gasket may have gone bad. If you have coolant mix that at 50/50 ratio into the radiator. It is colored green or pink and should be easier to trace to make sure the leaks are not in the other parts of the cooling system. It could be on the other hose, radiator or the engine.

Hello there and thank you for choosing fixya:
This is caused from 1 of 3 things
1 .the steering box being worn out Most common.
2 the tie rods are misadjusted or are worn out
3. the power steering pump is leaking and has either went air bound or has failed
I would take this as a serious matter and get this vehical into a shop and have it looked at asap ok?
hope this helps
Best regards MIke

Hello magarrrcr: My name is Roger and I will help you. Yes you can gain access through the trunk area. Remove the spare tire cover,jack and tire. Pull back the trunk liner. Remove the fuel sender access cover.Disconnect the fuel lines and the power wires. Remove the retainer ring and lift out the unit. It may be necessary to rotate unit as you remove it. NOTE (module will jump up when you remove the lock ring). Replace the pump and reverse procedure to reinstall the pump. Also beware that fuel system may be under pressure and is flammable. Watch for fuel spillage upon removal of the sending unit. Should you need further help please just ask. Please rate the answer. Thank You for using Fix Ya. Roger

I suggest check ECT (Engine Coolant Temperature) sensor, sound like go to bad or out range.

Regular is not causing your problem, while it is recommended that you use premium fuel, it will adjust timing for regular-your issue is something else. If it stalls at a light, is there any check engine light? Things that might cause this are Idle Air Control valve, the Throttle Position Sensor-it might also just need a good old-fashioned tune-up, plugs, plugs wires, air filter, oil change. fuel filter-since you just bought it, you have no real way of knowing what is good and what isn't, so you should either find a honest mechanic or do the work yourself. I have a 2001 Aurora, they are great cars and have great engines, but they can be a challange to work on, so first determine if the basic stuff is good-air filter, clean the throttle body, if the plugs and plug wires are old, change them. that's a good start, from there if you need an IAC or TPS, local junk yards are full of them (they use Caddy components too) so you can save a lot that way.

its does. but it could also the the belt and pulley on the water pump which is located on the drivers side of the motor. also check you power steering fluid... good luck

something in the "always on" circuitry is drawing too much current. find the fuse for the power door locks and remove it and see if that helps. power door locks seem to go bad and cause this in a lot of GM products. if that does not do it, then you are going to have to pull the fuses one by one and leave it sit overnight until you find the magic fuse. when you find that it starts, something on that circuit is bad, and you are going to have to live without it or pay to get it fixed.

you should have a tune-up done every 30-40 thousand miles(50-60 thousand kill).this is probably shorter than what a manufacture will say because they market low cost of repairs over time.but when the plugs are left in too long they will(can) seize in the heads causing more aggravation and money to fix.

electric fans come on only when necessary,, once the sensor gets the signal do they come on. if your car isn't overheating hes probably right.

You may or may not need to replace the battery. To check if it is a drain from one of the systems on your car; unhook the battery overnight and see if it kept the charge till morning. If it is still charged in the morning then it is not the battery.

It could be the instument panel relay or the instument panel dimmer switch.

This could be due to a fuel system problem, perhaps a clogged fuel filter. Since any debris in your gas tank would be settled to the bottom for the initial startup, the fuel pump picks up clean gas and has no problem supplying the injectors. As you drive, the circulation of the gas from the tank through the filter could cause the filter to plug up with debris, gradually losing power until fuel pressure is not sufficient to keep the car running. Try replacing the fuel filter and running some fuel injector cleaner through with your next fill-up.

Remove the retainers from the back,and remove the headlight as a whole from the front,and replace the bulb inside,do not touch the new bulb on the glass part. Should be 2 retainers holding the housing in place, one to each side. Good luck.

turn your a/c on which should send signal to cooling fans to operate, regardless of engine temperature. check for voltage on cooling fan wires. if voltage is not present check relays and fuses located passenger side front of vehicle under hood. if voltage is present, then i would replace the cooling fans

these 'shortstar' engines are well known for low oil pressure at idle, so look first to be sure it is full on the dipstick-it takes about 7 quarts to be full. If you are using 5w-30 oil (recommended), consider changing the oil and refilling with 10w-40, and buy a good filter like purolator Pure One, or a K&N, Wix or Delco. If theis happens even when cold, you have a problem that will be a lot more expensive-oil pump is going or gone, or you have worn bearings and this is going to require a rebuild of a used engine, very expensive.

The 1995 Oldsmobile Aurora with the Northstar engine has a timing chain.

Step 1:
Be sure the ignition key is not in the ignition, and the headlight switch is in the "Off" position.



Step 2:
Locate and remove the two headlight assembly screws on the top rail of the headlight assembly. Use the nut driver to remove them.


Step 3:
Place a rag between the headlight assembly and the bumper to protect the paint.


Step 4:
Wrangle the assembly outward. There is a guide pin behind the assembly on the fender side that holds it in place. This needs to be popped out of its socket in order to remove the headlight assembly. Pull slightly outward from the side, then forward and away from the car.


Step 5:
Locate the correct bulb socket (high-beam/low-beam). Disconnect the wire connector using the flathead screwdriver.


Step 6:
Turn the socket 1/4-turn counterclockwise to remove the socket from the headlight assembly. Remove the old bulb.


Step 7:
Insert the new bulb into the headlight assembly, and turn clockwise to lock into place. Be careful not to touch the glass bulb of the new socket. This could degrade headlight performance.


Step 8:
Reconnect the wire connector to the bulb. Test the light before replacing the headlight assembly, then turn off the lights again.


Step 9:
Reinsert the headlight assembly, making sure to align the guide pin into the socket. Replace the screws and tighten.
