I don't see an auxiliary thermostat or axillary water pump in Alldata's information and they are the best out there. Auxiliary thermostats on other cars can be used to regulate cold idle speed. Auxiliary water pumps are often used for cars with automatic climate control. Bentley workshop manual may be the best source of information for you.
