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.
