My Storm starts... runs for 5-10 minutes.. stalls, then steams...

There is NO indication that my 1993 Geo Storm 1.6L SOHC is overheating according to my temperature gauge on the bezel inside the car.

It runs for 5-10 minutes... dies and won't turn on again until it's
cool; so I think... must be Thermostat. However, the upper rad hose
is hot and the lower one is cool... so.. how could that be?

Anyhow, anybody with ANY suggestions would be a great help.

Thanks!
Scott

?? Not sure with this but can you pin point where the steam is coming from? Make sure coolant is full and check it's freeze protection too. - T

The steam is coming from the Radiator right where the Radiator fan sits... (this is only after (and just before) it has stalled...)

Thanks.... (heeeeelp)...

There should be NO steam there and the radiator must be full at the cap then the recovery tank. If price is important see how much to get it soldered but know how much a new one is first. Can't speak for Geo but some cars will shut down when too low on oil or coolant to save the engine. If you need to fill it up to buy some time and that works use 50/50 mix if you are dealing with cold weather at all. Just water is an emergency fix but you gotta correct that right away.

The stalling may be a separate issue. Need to know it's got coolant first. Good luck, -T

Hello... definatly has coolant... the steam occurs then the engine shuts off. (It shuts off VERY cleanly)...

HEEEEELP! :-)

Hi.

First off...

Can you shake the fan, (does it move a little at the connection to the engine?)
Also is there any coolant on the ground under the car? or under the fan. (maybe check the cooliant and top it off. Then start the car for 30 seconds. Shut the car off and look for water around the fans connection to the engine, if there is water or cooliant your water pump is the problem.

(the fan and fan belt actually spin the water pump, which pushes the water cooliant mix around the engine.)

If this is the case your water pump may have gone, which is why your coolant will drain and your cars computer will shut the car off.


IN Addition:
What state are you from?

I've heard if you use staight water it freezes at 32degrees, and if you use straight anti-freeze that freezes at 10 degrees, but the mix of 50 -50 freezes at -40 degrees.

I think tom is seeing if 1) you are low on cooliant, and 2) if you have a good cooliant / water mix in the car.
