We checked the senors, the fan runs fine, we run it for like ten minutes and it overheats and shuts off. It cools down really quickly, but we can't drive it very far! Please help!!

We ran the tests and no error codes came up, the only one that came up was P1684 which just says that the battery had been disconnected within the last 50 starts.

So even if we get no P codes could it be electrical or is it just something clogging the radiator?

Electronics in a car are sensitive! What you must realize is once a computer in a car gets flooded you must realize what is in the flood water. Iron is in dirt, mud, and most all water that has been in contact with the dirt. With this in view, I would have to think your computer is giving you false readings. Hint: Your computer is bad! Take the probes of a multi-meter, and place them in the dirt (in the ground), and set the meter to the Ohms scale. You will now notice that you get a reading, meaning the iron in the dirt is a conductor of electricity. You must start with a fresh computer (don't assume the codes are correct) to assure you are getting the correct information to the scan tool. One place to look would be the exhaust system may be plugged up to the point of not letting the heat go out of the engine. Run a pressure test on the cooling system to verify it is working properly. Look for a faulty thermostat, radiator cap, and air flow through the radiator fins as these may be filled with dirt and trash. Your problem is NOT a mystery, and don't assume the flood was the actual cause of the problem. The ignition timing being too low would cause it to overheat. You must rule out the possiability of an electronic as well as a mechanical problem. If the vehicle is getting a code for a disconnect of power, then you should also be getting other codes such as engine overheating as well. Temprature sensors work to ground. The more ground the sensor gets, the more the fan should come on. If the computer thinks the engine is not warmed up to 100 degrees, then it lowers the timing to make the engine warm up quicker. Until the computer see's at least 100 degrees, it will not go into normal operating mode, and keep the ignition timing lowered. In reality the computer cannot control many things until it does see tempratures above 100 degrees. Is the belt that turns the water pump slipping? Is there an air bubble trapped in the engine keeping it from cooling? Is one of the radiator hoses weak and collapsing? Try ruling out any and all mechanical reasons for this, and if this does not resolve the problem, replace the computer. Good Luck!

Change the radiator or just back flush it. Use a water hose and make the water go backwards in the radiator. This will dislodge the plug. Also you need to use a hose and clean out the air passages in the radiator and condensor. We have run into problems with the electric fans also that cool the radiator. Are you heating up setting still or running down the road. Without the a/c you should be able to run down the road without the fans as long as you stay above 35mph.

This i swhat you need to do. Replace the thermostat, plugs and wires, oil and filter, flush radiator, and change the engine coolant temperature sensor. Start there. I have done all of the above on my car before for maitainence reason and it's fairly easy. Just go to a local auto store and buy the manual. Let me know if you need more help. yummymummy223@yahoo.com

When you say you checked the sensors does that mean you put it on a machine and it checked out there were no problems???? or you did not receive any code errors???? may-be its your thermostat, but it could also be a sensor..... take it to Autozone or Oreilly and they can check it out for you and tell you what reading they get.. if any..

i'm slightly perplexed about this posting. in case you flow on petfinder, the rescue in ordinary words record 6 animals. Is it purely that the rescue don't have the elements even to record their animals? if so, we favor to mobilize volunteers to get down there and get pictures. human beings will foster and undertake, rescues will take dogs, yet we favor to get pictures. If someone can do this, commence posting on craiglist, deliver the tale to the media, and action will be taken. Paws Chicago has weekend radio and tv spots and may be in a position which could actually help you.

If your parents bought this car then they need some lessons on what to NOT do with a flooded car. NEVER try and start it until it is checked by a mechanic. - 10 points for driving it.

If you mean flooded asin under water, than you probobly have water in parts of you r engine the it is not supposed to be in. Check your oil and see what color it is. If it is a milky white color, than you have water in it and it is time to take your engine apart and have it cleaned before it is too late.

Replace the thermostat. - also check the water pump and any electrical components which lead to the sensors.

try changing the thermostat it may be stuck or it could be the gauge doesn't work correctly are you sure it is over heating not just the gauge showing this I had this problem and it ended up being the gauge

If the car was in an actual flood, you mave have water in the crankcase (oil) . Was the engine submerged in water?
