2009 Chevy impala overheating even after putting coolant


First of all, Alysa, that's not nearly enough information. The most common causes of engine overheating are: leaking hoses, radiator leaks, heater core leaks, a failed water pump, thermostat leak, freeze plugs leak, automatic transmission oil cooler leak and (I hope not for your sake) a cracked block or cylinder heads. Make sure you have the radiator filled with the proper amount and ratio of water and anti-freeze. Simply dumping more anti-freeze in there won't help. Check for leaks and check the thermostat before doing anything. Hope this helps. . .

Why my front brakes are overheating after I replaced/serviced the rear brakes pads ?


try bleeding the front brakes sometimes the valve will move to one side allowing more pressure to the opposite brake possibly causing this type of problem.

My kia sedona 2003 is overheating is it the water pump


Probably not the water pump. The most common cause is rusted out/leaking underbody heater rear heater lines. The steel portions of the lines rust and leak coolant. The low coolant level will cause the engine to overheat. If overheated repeatedly these engines will usually warp the cylinder heads. This will cause severe overheating and may damage the radiator and other components due to combustion gasses entering the cooling system. A cooling system pressure test should be done to check for external leaks, and a block test can be done to check for the presence of combustion gasses entering the cooling system.Make sure to check coolant level in the radiator when cold, NOT in the reservoir on the inner fender. This could also be caused by something as simple as a thermostat or radiator fans that aren't working.

Bat Main 4 (30A) fuse is blown and A/C blower is not working.


By A/C blower you mean the A/C fan by the radiator? it is possible that the fan motor has failed therefore requiring more amperage to try to turn it and as a result it blows the fuse. Disconnect the fan and install good fuse and turn A/C on if the fuse does not blow replace the fan.

Car running hot


Check fan relay and wire connections; if they are ok, and the fan work if you jump directly, could be the temperature sending unit, engine temperature sensor out of range or thermostat stuck. Stop the car, could overheating and damage other components and engine itself.

I just changed the alternator, the water pump, the thermostat and the serpentine belt in my 1990 Jeep cherokee, 4.0L in-line 6 cyl. However, my truck is still overheating, WHY?


Hello,
After all said and done,its a bit pertubbing that your car is still overheating.
However,there is still a particular component which if you don't replace,all the other components you replaced won't be of great importance.
I'll suggest you replace the rubber gasket which lies in between the engine compartment and the radiator, When this component is weak,the water mixes with the oil in the engine compartment,hence the oil looses its viscousity easily thereby it looses its ability to absorb heat which makes the engine to overheat automatically.

Thank you for using fixya.

I have a 2002 Nissan Altima 3.5L SE Engine that overheated while on a trip. The overheating affected some few components in the engine and they where replaced. However, the car refused to start.


Were the parts installed correctly? All wiring harnesses plugged back in? Did the Nissan quit running before parts were replaced? The overheating may have blown a head gasket.

Why is my car overheating. i replaced the thermostat and it still overheats.


Check your condenser, it could be clogged up for all you know. If your engine is overheating with all your cooling components working, its gotta be that. I cannot thing of anything else, unless your water jackets are blocked to death!

It's sounds like your radiator is plugged and needs to be replaced. or bar water pump.

Keep us updated (remember to rate this).

Overheating


Hi,

Most normal causes for overheating would be:
  • clogged radiator,
  • insufficient coolant level (radiator and reservoir);
  • too soft radiator hoses;
  • defective/leaky water pump (impeller);
  • water pump belt/tensioner;
  • thermostat (mechanical);
  • thermal switch;
  • radiator fan, fan clutch;
  • fan relay;
  • fan fuse.
In some instances, the fan only works in conjunction with the A/C and/or heater and therefore would only work if either of those two are enabled.

Should your particular vehicle be using a radiator fan with clutch, that could also cause the fan blades not to spin even if the fan motor is turning.

Pls check the above mentioned components.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards. Thank you for using FixYa.
