SOURCE: blower motor removal 1993 olds ciera 3.3

i worked for olds when that car was new. had alot of those motors go bad. you need to remove the p/s pump to do it by yourself-BUT you can remove the engine struts(mounts) and have a buddy(you trust) start the car and out it into reverse, now have him give it some gas so the engine rocks forward so you can remove/replace the motor/fan assy. - like that?
good luck

SOURCE: oil leak on manifold passenger side - v6 4motion

Get a can of Gunk and clean the engine according to the directions there (please do read them), with attention to the area around where the oil leak is.  Once you get the motor squeaky clean, you will be able to trace back to where the oil is coming from.  It may be running down the underside of a hose so you will need to look carefully.  You can do all this in the driveway.  You will probably have to let the engine get to operating temp before it will start leaking.

SOURCE: coolant leak on 96 olds ciera 3.1

Head gasket. The reason for the cold then hot readings is the cooling system is getting gas bound by exhaust gases. A simple intake leak would just make you loose fluid, but wouldn't cause the other symptoms until the coolant was very low. Which leads me to, is the coolant full? The head gasket most of the time will not leak coolant into the oil, but instead coolant will go into the combustion chamber, and exhaust gasses will go into the coolant. You don't see any white smoke until the leak gets extreme. Then shortly after that the engine hydro locks from too much coolant in the combustion chamber. There is a tester that will test your coolant for CO gas. That is the proof of a head gasket leak.

SOURCE: my 91 honda accord is leaking antifreeze

probably your lower rad hose. shine a flashlight around underneath and see if you see it reflecting off of a liquid trail, that will tell you where the leak is coming from. you can also get leak tracer to add to your coolant that will leave a more visible sign.

SOURCE: oil leak on 2.4 olds alero right side of engine

Two solutions.

Obvious is to tighten to valve cover.

The engine is actually designed to Not leak via the PVC Valve if working correctly there should in-fact be a negative pressure in the crank case.

Check and replace the PVC Valve.

Hope this tip helps

1988 oldsmobile cutlass cieara not overheating but windows inside continuously fogging over any answers...oil changes good everything runs good fan is kicking on appropriately car is driven by 75 yr old...

Fogging of the windows inside is usually caused by a heater core leaking.
That is located under the dashboard on the passenger side. If you have an odor of anti-freeze or the floor is a little wet on that side, that's a sure sign of it leaking. Have someone check for that.

1989 Oldsmobile Cutlass Ciera leaks oil on back side of motor. Where are the possible locations of this leak?

that all depends on how high the leak comes from, it could be from the intake manifold gasket if its high up on the motor,, a little lower would be around the bearing seals , and lower yet could be the pan gaskets ,, keep in mind that a lot of wind is generated when the motor is running at high speed, and a leak from the front of the motor could be blown to the back very easily.

I need to replace the water it hard to do?

The water pump is a pain to replace but very simple. Place it on jack stands supporting the tire on the front side of the engine. Normally the passenger side. With the tire removed you can access the inner fender shroud easily to give you more side working room and better lighting for sight. It is a constant up and down from the top of the motor to the side of the motor but is easy to do just time consuming.

Where is the power steering fluid located on a 1991 oldsmobile cutlass?

If memory serves, it is behind the engine/transaxle assembly on the passenger side, very low, against the firewall. If you look down into the engine compartment below the passenger side wiper arm, you should be able to see the cap. You will need a funnel to fill it, and you should not try to access it while the engine is hot. Gloves and long sleeves are highly recommended.

Passengers side rear view mirro replacement

On the inside trim, you can remove screws that are by the door handle, arm rest, under door and side of door and then gently pull back on the panel as there will also be retaining clips attached and you don't want to break them. You'll need to lift the door panel upwards in order to get it off the window ledge. Then you'll need to manipulate the panel and disconnect the door handle linkage from the door handle and disconnect the wiring for your controls. Then you can access the bolts that secure the mirror onto the door
