3. Drain the cooling system.
4. Remove or disconnect the following:
   • Air inlet duct
   • Water pump drive belt cover

   • Lower radiator hose and coolant bypass hose
   • Drive belt and drive belt cover
   • Air inlet duct
   • Negative battery cable
6. Refill and bleed the cooling system.

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.

Hi and welcome to FixYa!

Where does it leak? On the rack and pinion or on the power steering tank? If it's from the tank then it's just gonna be a hose problem will surely need replacement. If it's underneath the rack and pinion then the oil seals are surely worn out. This will need to be pulled out to gain access to the rack and pinion oil seals. Once they are replaced it will surely stop the leak.

Hope this helps and thank you for using FixYa! Have a good one!

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

You have a clogged heater core or the heater valve is not allowing the hot water to flow thru the system

Could be a lot of things, but if you have not replaced the air intake plenum gasket, this could be causing some of the issue. Spraying corborator cleaner around the gasket with the engine running should cause the engine to smooth out for a short period of time - just a diagnostic.

If the voltage is good to the heater blower motor , try lightly tapping on the motor near the end where the wiring enters while the fan is on.If it runs ,the motor needs replacing.

there should be a fuse located on fuse panel for heater motor( 30 A Green)....after you check fuse other possibilities are bad fan motor...bad heater resistor block.....bad relay...the resistor blocks are very common problems

With a fresh, new oil filter and all the oil drained, it takes 7.6 quarts.

Open hood, left front corner (passenger side front) might have a plastic cover over it.

Oh, here are some cool money saving links, if you are interested:

Never pay for auto repairs again!

check the relay for the fuel pump.ref to your hand book.should be easy to locate.

sounds like the pump in the Trans is getting weak, not putting out the presure it should. Off to the Transmission shop.

Could be the fuel pump relay staying on, it should turn off when turn off the key, sometimes the Tech will jump the system to drain the fuel out and may have installed the relay incorrectly.

fuel filter in need of a change perhaps?..cheap enough to change to eliminate it as a possibility

It is under the intake manifold towards the driver side

Driver's side of engine in the back.Look near the water tank towards the engine block.

That's because you need to bleed the cooling system, now. Here is a link to an article that will tell you how to bleed the cooling system on your car.

remove the coolant overflow tank, you have access then to removing the belt, and the pump
