[s-cars] Auxillary water pump

[Brian DeWyngaert Jr]

The switch is the second connection on the block past the thermostat,
according to the bentley guide.  Here is the exerpt for testing it.
 Turbocharger Coolant (TC) thermal  switch and turbocharger coolant
pump, checking

 -  Run engine until engine coolant  temperature gauge indicates more
than 100 C (212F). Cover  radiator if necessary.

 -  Stop engine.

 -  After approx. 5 minutes, electric  turbocharger coolant pump and
radiator coolant fan must switch on.


If electric turbocharger coolant pump and radiator  coolant fan do not run:

 -  Disconnect wires to TC thermal switch  and connect to each other.

 -  Electric turbocharger coolant pump and  radiator coolant fan must run.


If turbocharger coolant pump and radiator coolant  fan run:

 -  Replace TC thermal switch  -F98-.


If turbocharger coolant pump and radiator coolant  fan do not run:

 -  Eliminate malfunction using wiring  diagram.

My Wiring diagrams are .pdf..so i can send them to you individually if you wish.

Cheers,
Brian
