| 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. A slower than normal cranking speed may indicate coolant entering the combustion chamber. Refer to Engine Will Not Crank - Crankshaft Will Not Rotate . Remove the spark plugs and inspect for spark plugs saturated by coolant or coolant in the cylinder bore. Inspect by performing a Cylinder Leakage Test . During this test, excessive air bubbles within the coolant may indicate a faulty gasket or damaged component. 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 Engine Compression Test . | |
| Cracked intake manifold or failed gasket | Replace the components as required. |
| Faulty cylinder head gasket | Replace the head gasket and components as required. Refer to Cylinder Head Cleaning and Inspection and Cylinder Head Replacement - Left or Cylinder Head Replacement - Right . |
| Warped cylinder head | Machine the cylinder head to the proper flatness, if applicable and replace the cylinder head gasket. Refer to Cylinder Head Replacement - Left or Cylinder Head Replacement - Right . |
| Cracked cylinder head | Replace the cylinder head and gasket. |
| Cracked cylinder liner or engine block | Replace the components as required. |
| Cylinder head or engine block porosity | Replace the components as required. |
| Lower intake manifold damage or porosity | Replace the components as required. |
