SOURCE: 2003 chevy impala makes clicking noise/smoking thru exhaust

the clicking noise could be eiter a valve or piston. the smoke out of the exhaust means different things depending on the color and how much smoke. Check your air filter and make sure oil is not backing up into it. Also, it may be a good ideal to go ahead and change the oil even though you arent at 3000 miles, unless you just changed it. Change the PCV valve also, if itis clogged it will give you problems. Has the check engine light come on?

SOURCE: 2001 Impala Cooling Fan Not coming on ever and car

Cooling fan relay switch (in the fuse box uner the hood). Look for othger relays in there that are the same type number (they are all marked). If you find one that is the same as the cooling fan relay, then swap the two relays and check. (Turn on car and turn on A/C ... fan will start ... or not).

Fan motor could be bad (most likely).
If you remove it yourself, don't scrapr the radiator fins with the fan blades.

Hope this helps!

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.

My chevy impala keeps running hot eventhough the radiator and the fluid isn't getting hot. But after running for a short period of time or trying to drive for a short period the car runs hot and c


I would start by checking the fluid to make sure it's at the proper level, Then check to see if the thermostat is opening like it should. If you have good flow and you get heat inside the car but the car still overheats I think I'd be checking for blown head gaskets and head warp.

I have a 03 chevy impala keeps overheatin ive changed waterpump thermostat


Ok there are a couple of things to check, first the is to check your fuses for power and also check the relays to make sure thay working the best way to do that is to swap them out with a known good relay, another thing to check is to make sure your cooling fans are working and you can do this by turning on your A/C to verify both cooling fans are running at high speed if thay do not turn on tap the back of the fans motor to see if it turn on, If it starts to turn and then stop the you have to replace what ever one is bad. Good luck!

Car runs hot


If it was the thermostat, it would run hot all the time. Sounds more like the electric cooling fans are not working. Either the fans themselves are not working, or the coolant temperature sensor is bad and not sending a signal to the computor to turn them on. Have the fans checked first, then go for the sensor if it isn't the fans.
