DEFINITION: Excessive white smoke and/or coolant type odor coming
from the exhaust pipe may indicate coolant in the combustion
chamber. Low coolant levels, an inoperative cooling fan, or a
faulty thermostat may lead to an overtemperature condition which
may cause engine component damage.

2. |
Remove the spark plugs and inspect for spark plugs
saturated by coolant or coolant in the cylinder bore. |
|
3. |
Inspect by performing a cylinder leak-down test.
During this test, excessive air bubbles within the coolant may
indicate a faulty gasket or damaged component. |
|
4. |
Inspect by performing a cylinder compression test.
Two cylinders side-by-side on the engine block, with low
compression, may indicate a failed cylinder head gasket. Refer to .
