1994 Chevy Corsica Heater blowing cold air

About 4-5 days ago, I checked all the fluids. I put about a half gallon of coolant in it. Earlier toay is when the heater stopped blowing warm air. I checked the coolant and put the rest of the gallon in there and then some of a 2nd one. On the way home from work, the heater started working. I checked the coolant again when I got home and put a little more in it. I moved the car so I can see if it's leaking or nt.

I'm in Seward. The car was running fine this morning. I went to check on it after about 2 hours at work to see if I could see any leaks. There's about a half gallon of coolant underneath my car now. 2 yrs ago I had a new water pump and thermostat put in there when I put a rebuilt engine in there. Would either of these go out again so soon? When I bought the car, it had coolant caked all over the engine. I have an appointment Fri at No Sweat Auto here in Seward. There's only so many places to take a car here. And I won't be driving it until then. Thank you!

I don't know where the thermostat is. I'm just trying not to get ripped off. I've done about as much as I can with the time I have. I looked at the invoices from the car repairs and I had a new thermostat put in a couple years ago but not a water pump. My cousin mentioned it may be hoses. Sweat will be looking at it on Monday. Last time she did this, it was a cracked head. Crossing my fingers its not that.

Have you ever been to Seward? Sounds like you've been to the culvert.

No Sweat is in Emmitts old shop. Emmitt is still alive, he sold the shop this last year. I've had the best luck with them. Did you go to the combat fishing up here this last year?
