[DeTomaso] Sanden Compressors noises

The condenser is new, the evaporator flushed, a new dryer installed, and
the expansion valve replaced this last time under the same suspicion.
Something hitting the firewall sounded like an interesting theory. If my
harmonic balancer were the culprit, could it possibly go wonky (a technical
term) only when the compressor is engaged? I will pull the firewall out
this weekend and get a better look at it.

The condenser is new, the evaporator flushed, a new dryer installed,
and the expansion valve replaced this last time under the same
suspicion.A
Something hitting the firewall sounded like an interesting theory. If
my harmonic balancer were the culprit, could it possibly go wonky (a
technical term) only when the compressor is engaged?A I will pull the
firewall out this weekend and get a better look at it.

KirkA^1s system uses a A^3Fitted BeltA^2 pulley system that is a
little tricky

bearing very
