What happens if coolant temp is too high?

Hot, pressurized coolant and steam could erupt from the radiator, burning your hands. And never add cold water to an overheated engine; the abrupt temperature change can severely damage the engine.

How do you diagnose a cooling system?

During a Cooling System Diagnostic, one of our experienced tire and automotive service professionals will:

  1. Pressurize the cooling system to check for leaks.
  2. Perform an engine block test.
  3. Visually inspect for coolant leaks.
  4. Check all radiator hoses.
  5. Check the water pump and belts.
  6. Check the thermostat and cooling fan.

How do you test an engine cooling system?

Start your engine. When the engine is warm, visually watch the coolant in the cooling system to see if it is circulating. Tip: If the coolant is not circulating, then it may need a new water pump. The water pump test should only be done after you verify whether or not the thermostat is faulty.

Severe Engine Damage from Engine Overheating: Cracked Engine Block. Just like the cylinder head can warp from excess heat, so can the engine block. As superheated areas of the engine block expand and contract, it can form cracks leading to significant oil leaks, loss of performance and further overheating.

Is 230 degrees to hot for an engine?

For most cars, the normal operating engine temperature is in a range of 195 to 220 degrees Fahrenheit, though most dashboard temperature gauges don’t show an exact temperature. Instead, there are typically markings for cold and hot on the edges of the gauge and a normal range in the middle.
