Where is the block heater in a 2012 chevy impala ls

i think you are they should be color coded and match up directly .....however if you changed the wires completely they i would suggest find another 2003 Impala and either photograph it or write the sequence down a dealership will allow you to look at the motor even if you have to pretend you want to test drive it or just look it over

If you car is coming to temp but you get nothing from the heater the first place to look is the coolant valve for the heater core. It is sometimes called a mixing control. See if the control is jammed or your control cable is frozen or disconnected from this valve.

The valve should be somewhere near the cooling lines leading into the heater core. I am sorry, but they may be under the dashboard as well.

Good luck and be careful.

It sounds like you might need to replace your motor mounts, or get a tier allignement done. The allignment you cannot do yourself but the motor mounts you can this requires you to place a jack under you engine and undoing the motor mounts then replace them and take away jack.

I have replaced the radiator in my 2003 Chevrolet Impala LS. The car started running hot and shut down. Took it to a radiator shop and found a crack in the radiator. I have replaced 2 thermostats in the car already. I noticed water running from under my car today and it seems it was coming back out of the overflow. I am stumped as to what is going on with this car.
