16) Will it hurt anything if I go to AN fitting instead of a slip-on hose fitting?
If the fitting is the same size as the inlet and outlet you can use an AN fitting instead of a slip-on hose fitting. If AN fitting is smaller, the flow will not be as good.

17) Where can I get hoses?
You can purchase hoses at any auto store. (Braided hoses – Laughlin Speed Shops, Hutcherson and Pagen Charlotte.)

18) What kind of water pump should I use with your radiator?
You can use any standard water pump with a Griffin radiator.

19) Should I slow down the water pump or speed it up for better cooling?
You can overdrive the water pump 20 – 30% for better cooling.

20) Is it ok to run without a thermostat?
Griffin does not recommend running without a thermostat. Typically, engines operate optimally at 185 to 195 degrees F coolant temperature. The thermostat ensures this. Without the thermostat, the coolant will go below these temperatures causing higher wear due to differential thermal expansion.

21) What kind of thermostat should I run with one of your radiators?
You can use any good name brand thermostat with your Griffin radiator. A typical thermostat opens at about 189-190 degrees.

22) Can I use a restrictor plate instead of a thermostat?
Griffin recommends a thermostat over a restrictor plate. The restrictor plate does not offer flow control allowing higher flows at higher temperatures and throttling flow at colder conditions.
