[DeTomaso] Techno question: a fine mess--update

[Charles Engles]

Dear Long Distance Mechanics,

 

 

                   This morning the test drive without the AC belt is first.
If the noise persists, then I while the engine is warm, which is when the
noise most commonly occurs, then the alternator belt comes off.

 

                    I failed to mention that the mechanical and garden hose
stethoscopes both reveal essentially silent water pump, alternator body, AC
compressor and block.

 

 

                                          Warmest regards,  Chuck Engles

Charles,

 

Have you systematically removed one belt at a time and run the engine, to
narrow down the source?

   Dear Long Distance Mechanics,



                      This morning the test drive without the AC belt is
   first.    If the noise persists, then I while the engine is warm, which
   is when the noise most commonly occurs, then the alternator belt comes
   off.


                       I failed to mention that the mechanical and garden
   hose stethoscopes both reveal essentially silent water pump, alternator
   body, AC compressor and block.



                                             Warmest regards,  Chuck
   Engles
