Tip & How-To about Chevrolet Impala
It is winter and you jump in your car start it up and turn the heater blower fan on.
You sit and wait...and wait.... NO HEAT !
Here are a few easy steps to help diagnose the problem:
1) After vehicle is completely warmed up, open your vehicles hood.
2) Grab a pair of gloves. Put them on, now put your hand with your glove on, on the TOP radiator hose. ( The top black radiator hose is the largest hose on the top of the radiator inlet running to the thermostat housing, in most vehicles)
3) Be careful NOT to touch ANY part of the engines cooling fan(s). Is the radiator hose HOT or COLD to the touch ?
If the hose is cold the easiest repair is to replace the thermostat. The thermostat helps regulate the engine temperature keeping it approximately 195 degrees Fahrenheit, and helps supply hot coolant to run through your vehicles heater core to keep you warm in the winter.
