Common Problems With the Cooling System
Normally, your car's cooling system will work flawlessly for many years, but when a problem does occur, it is usually one of these:
If you see anti-freeze leaks on the ground or garage floor, it probably is due to one of these causes:
  • Bad radiator hose. A crack or break in a radiator hose can cause coolant to leak.
  • A crack in the radiator itself can also cause anti-freeze to leak on the ground. Replace any worn hoses or repair/replace the radiator.
  • Bad water pumps can also leak anti-freeze
If you are needing to add coolant, but cannot see any leaks on the ground, it could be due to 1 of these 2 causes:
  • Blown, or broken head gasket. If your coolant level is dropping, but you do not see any signs of leaks on the ground, check your oil. If the oil is milky, then you have a blown head gasket, allowing the anti-freeze to mix with the oil.
  • Bad radiator cap. Have your radiator cap pressure tested. A bad radiator cap may let steam escape, thus lowering the level of coolant.
Other Cooling and Radiator Symptoms Needing Repairs:
  • Coolant does not get cold - A broken fan clutch (if your fan is belt driven) or an electrical problem (if your fan is electrically driven) can disable the fan.
  • Engine overheats - There can be many causes of this. First, check the coolant level in the radiator. Next, check for any liquid leaking out of the weep hole in the water pump; leakage here indicates a bad water pump. If the water pump and coolant levels are good, check the thermostat. A thermostat that is stuck closed will not allow coolant to circulate. When the engine is warm, feel the upper radiator hose. If it is hot, then the thermostat is not stuck closed.
  • Engine takes a long time to reach operating temperature - The thermostat is stuck open, replace the thermostat.
  • There is no heat coming out of the vents - A thermostat that is stuck open will increase the time it takes to get hot air out of the vents. If you do not get any hot air, the heater core may be plugged or bad.
  • Coolant is leaking into the front passenger leg area - The heater core is clogged.
