#937 of 1448 94 Geo Prizm Owner's Manual??
Sep 14, 2005 (4:54 am)
I recently purchased a 94 Geo Prizm 5 speed stick, specifically to tow behind our motorhome. I am about 98% sure I can do it without any problems. But, I'd like someone who has an owner's manual to check and see if I have to stop every so often and start and run the engine for 15 minutes, as recommended on other cars. If anyone has an owner's manual for sale, I am definitely interested. I posted this same question on the RV Net.com forum, and received no responses. Just installed a Blue Ox baseplate on it. Surprisingly it went fairly well, without too much difficulties. It bolts into the "tiedowns" on the front of the frame.

I have the same model and had a similar problem for the past year. The problem started with a rough idle and eventually progressed to hesitation when starting from a stop and eventually stalling when trying to start from a stop. I did have cylinder misfire codes at least once a week as well. To make a long story short, I finally brought it to a toyota dealership and they diagnosed the problem as a bad mass airflow sensor and replaced it (~$325). I got the car back this morning and the car seems great, the engine idles wonderfully, nice and quiet and is very peppy when you step on the gas. I'm hoping that it stays this way and it might give your mechanic a clue to help you with your problem!

My brother's 95 geo transmission bit the dust with 80k original miles. Transmission shop says $2500. I located a used trans for $500. Can this be done by somewhat decent do-it-yourselfers? His trans is a 3-speed automatic, can a 4-speed automatic be installed or does it need to be a 3-speed?

Just talked to the Chev dealer, and they gave me the toll free number of Helms Inc. 1-800-782-4356. Ordered an Owner's Manual for the 94 Geo Prizm. $20.00 + shipping and handling.

#942 of 1448 Re: '90 Prizm Should I buy? [prizoner]
Sep 26, 2005 (2:25 pm)
I should've listend to Prizoner,
The car was very good for the first month or so, then overnight the exhaust got loud. Turns out the car needs a manifold and resonator pipe ($500 for those) I hear Prizm exhausts are short lived but it was out of the blue. The battery and e-brake lights come on at random, but they seem to be working fine. The car does run very well though and tranny is smooth (A 3 sd auto sucks, but it was always like that) The car went through a spell where it would randomly not start unless i gently touched the positive terminal, but when i would wiggle it hard the car would never shut off.. it hasnt done this in a few months though. Overall a good car.. I'll sell it for a couple hundred.
#943 of 1448 1990 Geo Prism Making Clicking Noise
Oct 05, 2005 (5:32 am)
Last friday my geo prism started making a clicking noise when you accelerate. Then it's also sluggish and doesn't want to and the clicking gets louder as you push the gas pedal down. We've checked the distributer(fine) ignition cables(fine) I just replaced the coolant temp sensor ( that was a pain) replaced the spark plugs, spark plug wires(fine) plenty of radiator fluid. We also noticed the engine got hot when only driven around the block. I have 4 guys trying to help since I really need this car working due to work. But we're all getting frustrated due to can't figure out what's wrong. Any help would be greatly appreciated.

Coolant temp sensor sends signals to the fuel injector, I believe. And maybe to the temp gauge on the dash also.
Actual cooling is regulated by a mechanical device called thermostat. I never replaced one on Prizm so I am not sure exactly where it is, but if you carefully trace the path of the radiator hoses, you will find it.
I hope the "clicking sound" does not imply internal damages to the engine due to overheating... Thermostat should be less than $20, but excessive overheating can ruin the engine. Blown head gasket also results in overheating, but for $20 you should replace the thermostat and see what happens.
