Help please, it is about to get super cold and I need my heater core replaced this is my only transportation to/from work and I am already really feeling the cold. I am looking for a good shop/person in the Columbus or Mount Vernon area that can replace the heater core for me. Any suggestions would be greatly appreciated! Trying to avoid dealerships so I can avoid have to use OEM (difference of $300 in just parts). Thank you in advance!!!!
