'04 Elantra Won't Stay Heated
So I just purchased a used '04 Elantra with 73k miles the other day and it test drove very well. Today I was driving on the interstate and realized that the car just would not heat up when the dreaded check engine light illuminated. I took the car to AutoZone and put in some more antifreeze and noticed that the car would warm up when I would idle or drive fairly slowly but then cool down rather quickly when I sped up. I think something just isn't holding its heat. Any suggestions?

Where did you put the antifreeze in? In the reseviour on the side, or the radiator itself? It takes a while to work the air out if it was low.
Depending on where you live, it has been extreemly cold. Put a piece of cardboard in front of the radiator while it's really cold like this. You can cover most of it, it will be ok and not overheat as long as it's got antifreeze.

Ok, well go get your check engine light checked. Go back to Autozone and ask for a free code scan, write them down, and tell us what they are. If your not getting heat, and you know you have antifreeze, then cardboard is a wonderful idea to get heat. It's not the heater core or a temp sensor. It could be a thermostat that's stuck open.

I'm quite glad I posted on this forum as these responses are really reassuring! I was planning on taking the car in this weekend to get it looked over anyway, so I'll let everyone know the results probably by Monday. Thanks!
