Hello. I have a 2012 Chevy Cruze. Last week my temperature gauge kept showing hot. I discovered I was low on coolant so put more in. Now my car has no heat. My fan is blowing but it’s not warm. I went to look at the coolant again but now the coolant cap won’t come off. Ugh! I just have no money for this right now! Any idea what’s wrong? The car has an odd smell to it but it dies t smell like antifreeze

Wait until the car cools down. Try it again.

If that doesn't work take a large pair of channel locks and use that for more leverage to twist the cap off.

Remember it is plastic so don't over do it.

Try turning the coolant cap while wearing rubber gloves. I often do this when I can't open jars with my bare hands.

For future reference I have a pretty good idea (been there done that)!
You have to pressure your cooling system, by heat or air compression..
and then unscrew just a few turns, and wayt for the pressure to move the cap valve inner body, stuck by a swollen O-ring!
