2 years ago, my mother, previous owner, replaced water pump with dealership in Colorado. The car was around 2.5 years old. And less than 30,000 miles. About 6 months ago my overflow container was so hot it cracked. Idle hot came on. New container was purchased. 2 months less ago my car started to idle hot according to message on speedometer and NO hot temp was visible. Also, no check engine light was on. Water pump went out again. Less than 70,000 miles. Replaced water pump. Thermastat. Thermostat housing AND overflow because warped lid due to HOT. This weekend (XXX) my car has no check engine light, less than 70000 miles. Ran hot again. Smells like an oily sweet smell. Looked at oil cap. Milky substance. Appears head gasket is now out.
