How would you replace the radiator on a 1991 Geo Prizm 1.6L?

If you have an automatic transmisssion, there are two lines that have to be removed. Relatively easy as there should be two clamps that have to be loosened and then the rubber line can be pulled off. Be sure to tie them up as tranny fluid with otherwise leak out.Allow the engine to cool, if necessary. Remove the radiator cap. Remove the passenger side splash guard from under the car. On the on the engine side of the radiator, near the bottom, on the passenger side, is a petcock bolt. Loosen this bolt to drain all the radiator fluid. Clean up any spills so no critters, human or otherwise, try to drink it or sue you cause it's on the ground. Disconnect the radiator fan at the wiring harness near the radiator on the drivers' side. Disconnect the upper and lower radiator hoses wherever it's easiest for you. (if they feel flimsy or too squishy or you even THINK they'll fail, replace them. If you lose a hose on the freeway that engine will overheat and warp the head faster than you will be able to stop the car. On that you can trust me). On top of the radiator there are two brackets that hold it to the car. Remove these. Don't worry about the bottom, there's nothing there to worry about. Just yank 'er out.

How do you replace the headlight assembly located on a 1994 Geo Prizm?

Real simple, just open the hood disconnect the wire harness from the bulb, and then remove the screws holding it in. There's only two of them according to the manual.

There will be a total of 2 screws, 1 bolt, and 2 nuts to remove the assembly (and, of course, disconnect the two bulbs). The 2 screws are Phillips head and the bolt will need a 10mm wrench (they are on top). The 2 nuts are also 10mm and are behind the clear turn light rounding off the the side of the headlight assembly. Only one screw holds that in and a peg in that light faces straight ahead, so remove that by forcing that light forward. The assembly now only has a friction pivot on the bottom holding it, this also must be pryed straight forward. They will not pop off easily as they are a tight fit.

What are the timing marks for a 1990 Geo Prizm?

Timing marks 1990 GEO Prizm GSI (4 AGE)The crank timing mark for the 1990 GEO Prizm GSI (4 AGE with twin overhead cam) is a notch found on the inside rim of the crank pulley. Set this notch to 0 for TDC on the Crank sprocket dust cover.

The intake and exhaust cam sprockets have an indention on one tooth of the sprocket. Aline this dot with the crease in the back plate. The intake crease is a vertical crease at 12 oclock position and the exhaust is a vertical crease slightly before the 12 oclock position.

If cam sprockets have been removed make sure you align the cam shafts before reinstalling sprockets. Set the knock pin of the intakse shaft to the 12 oclock position and the exhaust shaft to the 5 oclock position. Once this is done install the sprockets so their respective timing marks line up with the marks on the metal back plate.

How to change third brake light bulb in 1996 GEO?

I just did this to my sons car, very very easy. Tools required: One small Phillips screw driver. On the inside of the car on each side of the third brake light unit there is a small plug type tab. Press in on the center with the Phillips screw driver, a ball point pen will work as well. It will just pop in about a quarter inch. Next grab the outside lip of that same tab and pull the plug out. Repeat on the other side. This will allow you to lift and remove the plastic covering. Next you will see a small Phillips screw on the left of the bracket holding the actual light bulb. Remove with Phillips driver, this will allow the light assembly to come out. Unscrew the bulb replace and assemble. Took all of 5 minutes. Replacement bulb is a 921 or a 921LL Only difference in bulbs in the LL is suppose to last longer, more expensive too. Still only 3 bucks though. Good luck

What is the proper tire pressure for a Prizm?

Check your owners manual it will say, also the sidewall of the tires will say. I would say 35psi Paul from canada

NEVER look at a tire sidewall for pressure numbers! Different car models require different pressures. A tire can be placed on many different models, so how can a tire tell you what pressure YOUR car should have? CHECK THE OWNERS manual or inside the door sides or the glovebox for your car's pressure. THE ONLY TIRE PRESSURE LISTED ON A TIRE TELLS YOU THE MAXIMUM PRESSURE THAT THE TIRE CAN TAKE --IT HAS NOTHING TO DO WITH WHAT YOUR CAR REQUIRES.

I consulted the user manual for my '93 Geo Prizm, and it said "Geo does not make tires...check the information supplied by the TIRE MANUFACTURER!" I could not find any info on the door posts...HUH?

Open the glovebox and look at the sticker in there. Odd spot I know... If you have the 175's on it says 29psi front and rear.

How do you remove the rear speakers of a 1996 Geo Prizm?

You have to remove the rear shelf, the rear speaker covers are attached to the shelf. You can see the connectors underneath from inside the trunk. Be carefull not to scratch your defroster lines in your back window when removing the shelf. You may need only pop up the front portion to access the speakers without compeletly removing the shelf. Removing the backseat if its a non LSi model might help.

Does a malfunctioning Vehicle Speed Sensor on a 1990 Geo Prizm have to be repaired by a 'qualified service professional' like the repair manual says?

Heck no, if you can afford a new one, there's only a couple of small bolts that hold it in. I think they're 10 mm. All you have to do is disconnect the wire plug from it, take out the bolts, remove it, put in the new one, reconnect the wire and drive on. They are a PITA to get to but you CAN do it yourself. A new one at Autozone runs about 188 dollars.

Would a defective thermostat on a 1993 GEO Prizm cause low readings on the temperature gauge and little heat in the car?

Yes! Thermostat stuck open. Replace thermostat. It could, but the thermostat is normally open when the engine is warm so you should only notice this when the engine is cold or warming up.

How to replace antenna on 1994 Geo Prism?

Just did it... You have to buy an exact OEM replacement. Unscrew the antenna unit by removing the two screws. Pull out the remaining metal antenna and the wire. A plastic tube that houses the antenna will need to be removed. I was unable to remove the antenna cable as it is clipped behind the dash. I cut the wire leaving about 6 inches remaining above the roof of the car. Remove the inside trim along the top of the driverside door, all the way to the fron window. Additionally, remove the small trim piece along the edge of the door beside the drivers side dash. With the new antenna unit, begin to thread the antenna cable through the existing roof opening along-side the original cable that remains. As you thread the cable through the body, take notice of a hole in the body on the inside of the car above the drivers side door. You should see the new cable pass by the hole. Pull the cable through the hole.(I had to enlarge the hole to accomodate the plug that attaches to the radio. I used a dremel tool with a grinding bit to slightly enlarge the hole.) Once you get the antenna cable through the hole, pass the metal antenna and cable through the hole in the roof until you can mount the antenna housing to the roof using the two screws. Run the cable under the door trim and down under the dash. Make sure the new cable does not interfere with your steering wheel or and thnig else. I hope this helps you. I would have loved to see this before taking on this project. I just replaced the antenna on my 1994 Geo Prism and found that only one piece of trim needed to be removed. It is the piece with the fuse box door on the inside drivers side. Once you have it removed you have access to a plug and cable that runs from the antenna to the radio. Unplug the antenna remove the screws on the outside, pull the old antenna and cable out,put the new antenna and cable in, plug it into the cable running to the radio, replace the screws and trim, job done! I followed above answer with one modificarion. Only had to remove fusebox molding. Unscrew antenna from roof.cut antenna wire and leave as much as possible. Pulled out clear plastic piece. Taped end of new antenna wire to end I cut off old antenna wire. Pulled new wire thru and connected to wire that goes to redio. No grinding.

How do you replace a starter on a 92 Geo Prism LSI or GSI?

Well, I asked this question aboved, but I found the answer myself. Here's what I did:

First off, the location on the starter is behind the engine block (if you look up underneath your vehicle, you will see it past the front exhaust pipe).

What you need to do first is disconnect the negative and positive battery cables.

Next, take of the air cleaning unit and it's base on the right side of the engine. You will disconnet a cable connected to the air cleaning unit when you do this. This will allow you room to stick you hands underneath the starter to remove the lower bolt (explained later). After removing the air cleaning unit and the base, jack the car up and place safety stands on the vehicle.

(Note: It might make it easier for you to remove the starter if you take of the the front exausts pipe underneath the vehicle)

Now you will locate the ignition switch lead, and the positive battery cable lead, which are at the far bottom of the starter, on the starter.

The ignition swith lead is a black square connection. Disconnect the connection.

The positive battery cable lead is next to that, but is held in by a small nut. Unscrew the nut and disconnect the positive battery cable lead wire.

Next your gonna locate two bolts that are holding the starter assembly in place (which are on the opposite end of where you just disconnected those wires).

This my be a little tricky to find without being able to show you a diagram. You may want to look up pictures of a 1992 Geo Prizm starter on line so you can see where they are at, or go to an automovite store and have them show you a new starter.

But generally, there are two bolts connected to the flywheel holding the starter. The top bolt is facing the left of the vehicle, while the bottom bolt is facing the right.

After undoing the bolts, you can take the starter out. Installation is reverse from above.

(Note: When installing the starter, hand tighten the bolts first to prevent stripping)

I basically went to an autoshop and asked to see the starter, so I could located the parts of the starter on the vehicle. I also downloaded some pictures off the internet from people who sold starters. This helped me locate where these connections are.
