Last couple of nights I have been driving, I have been smelling coolant. No signs of a leak anywhere. I had my waterpump replaced less than 2000 miles ago. I checked my resorvoir today and it was low but it read below "cold" . Usually where it reads all the time. (while the engine is actually cold) But I checked my radiator and it was low. I didnt even see where the coolant line was really. I didnt check it with a flashlight though so im not sure where the level is. The engine doesnt overheat at all, but I havent had the car running more than 10-15 minutes at a time. No performance issues or anything like that, but I was thinkin about bringing it in. I have my warranty still from CarMax, but was wondering if a flush and refill would even be worth it right now. Anybody think its an internal problem in the engine? Should I just add water for right now for temporary solution before bringing it in? Thanks

 

I'd take it to them. Don't do anything to the car as it may void the warranty on work they did. Fill it if it's low though.
