#954 of 1448 3 speed vs 4 speed auto
Oct 23, 2005 (4:18 pm)
I'm thinking about buying a 2001/2002 Prizm but only want one with the 4 speed automatic. How do you visually tell the difference between the two. I'm assuming that very few sellers will have the original window sticker. Is the option code listed on the door as witrh other Chevys?
Wish they were still making this car new. 40 MPG in a automatic Prizm beats the hell out of a smaller less powerful Aveo that can only manage 35MPG

Check coolant level often. It you have to keep adding antifreeze in the radiator, you have a leak somewhere. If the coolant disappears but you see no external leaks, blown head gasket is a possibility.
Thermostat failure is fairly common so let's hope that solves the problem.
If it doesn't solve the problem, check ignition timing with a timing light. Check if the timing belt is tight. Clogged (internally or externally) radiator is another possibility. You can squeeze a radiator hose in your hand and see if the coolant is flowing once the engine warms up. Hoses should get hot as the engine gets hot, if the water pump is indeed circulating the coolant (be careful doing this). If the coolant is circulating, water pump should be ok.

The 4th gear on 4spd model is overdrive. There is a little push button switch on the side of the shifter. Dashboard should have an indicator that comes on when the overdrive is off. That's usually that way it's set up, although I am not exactly sure on 2001/2 models.
Toyota Corolla is still in production and it is almost identical to the Prizm, except that the Corolla has gone through a model change since the last generation of Prizm/Corolla co-production. My GF has a 05 Corolla, and it is much quieter and more comfortable than my 94 Prizm.
The new bargain is going to be Toyota Matrix/Pontiac Vibe. They are much more spacious than the Corolla and very good on gas. I expect the Vibe to depreciate in value much faster than the Matrix, and it will be just as reliable as the Matrix.
#957 of 1448 1990 PRIZM HAS OIL IN WATER
Oct 31, 2005 (9:19 pm)
My prizm has been using about a quart of oil a week. I could not figure out where the oil was going. There were no signs of oil leakage under the car and no smoke from the tailpipe. The car was running a little warm so I flushed the radiator and saw there was oil in the water. Also there is thick black greasy film on passenger side of car, front tire and outer front door panel. What is causing this? I have asked several people and they don't know. If it was a blown head gasket, wouldn't the water be in the oil instead of the oil in the water? I am a single female and have to do my own repairs. I rely on this car to support myself and would greatly appreciate any advise I can get. Also, I took the thermostat out and the car doesn't run on the hot side any more. I figure that the oil in the water had clogged up the thermostat. If anyone knows what may be causing this, please let me know.

Oil leaking into the cooling system "overfills" the cooling system, and the coolant is overflowing from the coolant reservoir. But the coolant is contaminated with oil, so the tire well and door get coated with grease. Does this sound like a possible senario? How much oil did you find in the cooling system when you flushed it?
I would not assume that you need a new head gasket.
Some cars have engine oil cooler inside the cooling system. One possible location for this device is near the intake manifold. This takes hot oil from the engine to the coolant (in separate a tube of course) for cooling of engine oil. There may be a heat exchanger (should look llike mini-radiator within the cooling system) bathed in coolant, and if there is a leak, oil will end up leaking into the radiator.
I read somewhere that oil pressure in this oil cooler is typically higher than the coolant pressure, hence oil leaking into the coolant, not the other way around.

Update..after a new radiator, new fuel injectors, new temp sensor, new spark plugs and spark plugs wires and checking the compression which was real low on some of them I threw in the towel and traded it in for a 2002 Ford Focus SE. Hey the car did me good til the final stretch and with 185,000 was ready to be put to rest. So thanks for the suggestions you did give in a timely and helpful manner.
But hey shocked the guys when I got the book out and replaced some of the parts myself lol
#960 of 1448 Connection Between PO171 Code and A/C Problem?
Nov 21, 2005 (5:47 am)
I've been dealing with the PO171 "Left Bank Lean" problem since May on my 2000 Prism (94K miles). I've had sealant added around the manifold, replaced the O2 sensors, replaced the gas cap, had the dealer clean the system (including the MAF allegedly), used premium gas with Lucas injector treatment, all to no avail--the check engine light will go off (or I'll turn it off via the fuse) then come back again (always 171, though I did get a PO300 "Random Multiple Cylinder Misfire" once--I appreciated the variety).
It's an annoyance, really, since the only symptom other than the light is a hestitation sometimes when accelarating from a stop (I'm extra cautious about pulling into traffic now!).
Out of solutions other than having the fuel filter replaced, which I imagine would be expensive as heck given its location, I'm wondering whether the PO171 problem may be related to another issue I had at the beginning of the summer, namely my A/C refusing to cool. I added more refrigerant without any luck, then replaced the filter/orifice, which was completely clogged, and refilled with coolant. Both times the car cooled for a day, then stopped. I have an ultraviolet light to pick up the dye in the coolant, but I can't detect any leaks.
I'm out of ideas, so I'm wondering whether ya'll might think there's a connection, however unlikely, between the PO171 issue and the failure of the A/C to cool. Or, if you have more suggestions on how to remedy either, I'd welcome them!
#961 of 1448 help for weird starting problem
Nov 26, 2005 (9:00 pm)
I have a 92 Geo Prizm with 144000 miles. Runs fine except that it's taken to not starting when the temperature reaches 30 or below. I've had the starter and alternator and ignition replaced and it has a new battery. I don't want to put in a lot of money on this car since it's 13-years-old but I would like to get through the coming winter.
Anybody else have a problem like this?

Update: I took the car back to a dealership where I was told to expect to leave it for several days while the mechanics drove it until the check engine light came back on. Because the Prizm computer is so small, they said, the best diagnostic info is obtained as soon as the light goes on.
However, I heard back from the dealer an hour or two after I dropped the car off. As with other folks' experience with this problem, it was the mass air flow sensor. Parts and labor and a new sensor cost me $352.99 overall. Pricey, but the car runs like new now, and even the A/C seems to cool quicker (though I reckon I have to wait till summer to test that out fully!).
