More than likely it is a bad radiator cap. the pressure seal is leaking on cap.

Try to replace a new rad. cap-if still leaking & original radiator-then the tanks are wearing down,try putting some stop leak in it momentary-radiator may need to be replaced-not that big of job,you can do yourself-shops will charge $$$$$ hope that helps-good luck!

Have an 03 chevy impala runs hot but radiator cap is cold can put water in it and leaks out


What is your question? You should not operate a vehicle that overheats. You should not put just plain water in a cooling system for a car. You can see the leak? You should get it fixed before any more damage happens to the engine. Failure to keep the engine cool can cause a host of problems and none of them are cheap to fix.

In 2005 chevy impala the heater only gets warm sometimes. Other times it blows cold air. I put fresh antifreeze in. And there is no water on the floor of the car


The adding adding coolant means you have a leak somewhere, and low coolant level will cause this. How often do you check the fluid levels? Check for leaking hoses, weak radiator or expansion tank cap, leak at the water pump, and leaks around the radiator.

You may have an air pocket in the engine block. Make sure it is bleed properly. Also, some water pump impellers have been known to breakdown, made of plastic. A head gasket leak can also appear to be a boiling over condition.

Can i still drive my 06 chevy impala with a warning light of engine hot a/c off?


It's not a good idea to drive a car that is overheating. Permanent engine damage can occur. You need to find out what is causing the overheating problem. First, check the coolant level. Do this with a cold engine to avoid burns when you remove the radiator cap. If the fluid level is low, replenish with a 50/50 mixture of anitfreeze and water. Be sure to use an antifreeze that is compatible with aluminum. With the radiator full, run the engine until the top radiator hose is warm to the touch. Carefully remove the radiator cap and observe the coolant for several minutes to determine if it is flowing through the engine. If the coolant does not seem to be flowing, then you need to replace the thermostat. If you replace the thermostat, it would be a good time to flush the cooling system with a good commercial product such as Prestone Super Flush. Follow the directions closely. Refill the cooling system with the correct antifreeze. Avoid Dexcool antifreeze. It has too many problems associated with it. If the warning light is still on, you may need to use a scanner to clear it. Drive the car normally and watch for any signs of overheating. Keep a close eye on the coolant level. If it was low earlier, that could mean you have a leak. Let me know the outcome.

My temperature gage is going over in the red and my heat is not


Check the sensor which controls the cooling fans that cools the radiator it prevents the engine from over heating and allows the temp gauge to stay at normal range.recently had problems with my 2003 impala overheating it was the sensor had the thermostat replace as well.

Overheating 2001 chevy impala


Believe it or not, new thermostats can be bad. Did you maybe get some adhesive on the thermostat preventing it to open fully? Is the thermostat installed with the crown up? The only other thing that I can think of, if it's a closed cooling system and the wrong radiator cap is installed, it won't hold the pressure, therefor overheating. The other thing may be the water pump. Many times the impellers will wear down internally causing to low of water flow.

the best thing to get is the Haynes manual for your car at advanced auto or autozone or somewhere like that and the book will tell you how to take everything apart and put it back. i think the manual is about $16.00
