Fan kicks on when it starts to get hot, smelling antifreeze when heater is on or ac, but there is none on the floor board, leaked antifreeze out the driverside right behind the wheel when it got really hot..puts out hot air, or cold, depending on what you have the settings on..and just noticed it's leaking oil from the passenger side, near the water pump..Any thoughts? 2.2

 

uuggh..Just checked the coolant res. and there's oil in it...nice..

 

Sounds to me like blown Head gasket,or perhaps crack in the head.Pulling the top end is not really hard to do if you have the tools,and space.
