I was at this shop for a no heat problem and was quoted $800 for a heater core. Didn't have the money at the time so I picked up the car and was driving it like this for the time being. In the meantime car started to overheating so I checked the antifreeze, it was low. Well I got some from local parts store and filled up the radiator and reservoir bottle and guess what the heat came back. I had a loose hose clamp that's all. I spent $11 for antifreeze and tighten a clamp, better than $800 for a heater core!
