Cooling System: Overheating - The Usual Suspects
« on: December 26, 2007, 15:45:46 »

Causes of Overheating

Car overheating?  The usual suspects are:

  • Insufficient coolant - possibly due to a leak somewhere
  • Air in the cooling system
  • Leaking head gasket
  • Leaking intake gasket
  • Improper coolant mix (should usually be 50/50)
  • Contaminated coolant (rust or oil)
  • Bad radiator cap
  • Bad thermostat
  • Clogged radiator
  • Clogged block water jackets (engine needs to be flushed)
  • Bad hoses or no spring in hoses (they can collapse and restrict coolant flow)
  • Loose fan belt
  • Defective clutch fan (allows excessive fan freewheeling)
  • Bad water pump
  • Missing fan shroud
  • Exhaust system blockage - clogged muffler,cat or pre-cat
  • Incorrect ignition timing
  • Lean air/fuel mixture
  • Fan too far away from radiator - should be within a couple inches away
  • If air conditioning - dirt, leaves or trash in A/C condensor
  • Cracked head
  • Cracked block


Always check the easy stuff first.
