Heater problem
2007 Saturn Ion Two Wheel Drive Automatic

i was wondering if I could get a step by step on how to change the heater core. I have done this many times before just on older cars. The lady that I am doing this for was told that it would take 9 hours and around $1000 to repair. I am just trying to help her out because she does not have the money to get itfix by a professional.

Heater Core Replacement

Tools Required
*SA9111E Hose Clamp Pliers

Caution: With a pressurized cooling system, the coolant temperature in the radiator can be considerably higher than the boiling point of the solution at atmospheric pressure. Removal of the surge tank cap, while the cooling system is hot and under high pressure, causes the solution to boil instantaneously with explosive force. This will cause the solution to spew out over the engine, the fenders, and the person removing the cap. Serious bodily injury may result .
