	Heres a freebie tip from an ex G.M. auto -  electric tech......
1. There are several causes of failure to turn over @ high temp.
   A. weak starter solenoid that will not pull the plunger back due to
      shorting of some of the solenoid windings from deteriorating
      insulation .
      RESULTS :NO CLICK , NO SPIN 
   
   B. weak solenoid action due to mechanical wear of the plunger.
      RESULTS : NO CLICK , NO SPIN

   C. weak solenoid action due to accumulated oil from an oil leak.
      This builds up into a gummy mass inside the solenoid , and
      each time it gets hot , it cooks down a little thicker.
      (usually from close proximity of an exhaust pipe , but I dont
      think this is your case because chevette's exhaust is on the
      opposite side of the engine .)
   
   D. a dragging starter . The starter armature rubs the field coils
      due to worn bushings.This is aggravated by high temps due to
      expansion of the parts.
      RESULTS : CLICK , SLOW OR NO SPIN , BATTERY CABLES GET HOT 

   E. excessive current draw from insulation breakdown in starter 
      windings.
      RESULTS : CLICK , SLOW OR NO SPIN

   F. weak battery . Most engines require more current to spin when

      hot. Get a load test on the battery FIRST.

   G. loose battery cable at starter .
      RESULTS : MAY START HOT AND NOT COLD ,COLD AND NOT HOT ,ONLY ON
      ALTERNATE  TUESDAYS !

2. Changing starters in most chevettes is a pain !

   A. If it has PS & PB it is often easiest to remove the steering column!

   B> If it is a "plain jane" it is not bad except for the top bolt.

      (there is a space in the intake manifold you can get thru using
       extensions and a flex socket - 15mm if memory serves )

3. Regardless of whether it is the starter or the solenoid , once you have determined that 
the battery is not at fault , and that the cables are tight ,proceed to install
a rebuilt starter , complete with solenoid from a reputable manufacturer. On 
a chevette , the savings realized by only changing the solenoid or only the
starter are not in any way worth the aggravation of doing it again.....


                                 HAPPY MOTORING !
