On certain vehicles, the coolant heaters may be missing a combustion chamber (a.k.a. burner tube). When a coolant heater is defective, a flame will be noticed exiting the exhaust pipe at the bottom of the unit. This condition could result in an engine compartment fire. Correction: A combustion chamber will be installed in affected units.
