Default 2001 PT cruiser issue

So just recently my PT Cruiser has been letting off steam or something from under the hood on the passengers side. This usually only occurs in the mornings on my way to work. The car doesn't seem to be overheating at all but depending on the day it will kind of flirt with going over the halfway mark but then come back down quickly. Anyway I was wondering if anyone knew of what may be causing this to happen (at times it smells like antifreeze and other times it doesn't that I have noticed).
Also when I open up the hood I don't see where its steaming from at all.

That "steam' is most likely the compressor letting out R134 because of overheating. Even if it's cold outside and your not using the air-conditioning, the defrost mode also uses the compressor. Most of the problems we've seen involve the 2 speed radiator fan. If the high speed isn't working, everything heats up and all kinds of problems rear their ugly heads. Above 35mph, there's enough air coming through the front end that the fans shut off and everything goes back to normal. Below that and everything starts to heat up again.

Opne the hood & turn on the A/C - if the engine fan doens't come on, you'll need a new fan.
Is coolant level in overflow okay?
If overflow gets empty, you can get air in the radiator, that will cause spikes in the temp gauge - when engine is cold, top off radiator with coolant and then fill overflow bottle.
