    Some possible causes are waterpump, cooling fan issue, coolant tempature sensor. If your oil light comes on its because your low on oil or past due for a change which should be a separate issue. Inspect for proper operation of fan(s) and if pump is making a squeal type noise replace. Otherwise try cool. temp. sensor replacement. Hope this will fix.

    If the car is only blowing cold air, you might want to try bleeding the air out of the coolant lines. If that doesn't do anything, the heater core may be plugged.
