*Water pump and crankshaft pulleys sized according to what was on the engine from the factory. On a street motor, shoot for 1.2 to 1.3 times crank speed for pump pulley speed. This is usually true until you get to 3.55 gears and numerically higher, then 1 to 1 works better. Most all 1960's muscle cars are 1 to 1. Pump speeds over 4200 sustained cause cavitation. Nascar is a good example with roughly 3.5" crank pulleys and 8" waterpump pulleys for their 9200 rpm engines''(confirm)'' | *Water pump and crankshaft pulleys sized according to what was on the engine from the factory.

| − | * | + | *On a carbureted motor, most of us use a 180 degree thermostat, although a little hotter thermostat (190-195) may make the motor more responsive and add a little fuel mileage. It may also help to burn off some of the by-products of operation, such as moisture and acids which form and get into the oil. Motors using EFI induction should be operated at the temperature specified by the factory for that particular motor to prevent false input to the computer and consequent problems.

*Ensure that there are sufficient openings in the engine compartment to allow the exit of all the air drawn into the compartment. This might require the removal or surgery of inner fender panels or using spacers to raise the hood of the car up an inch or two at the back. | *Ensure that there are sufficient openings in the engine compartment to allow the exit of all the air drawn into the compartment.

| − | *Maintain the proper coolant/water mix to prevent freezing up in winter. Water transfers heat better than coolant, but some coolant must be used to prevent freezing. | + | *Maintain the proper coolant/water mix to prevent freezing up in winter. Water transfers heat better than coolant, but some coolant must be used to prevent freezing. Using a 50/50 mix of coolant/water is a necessity for motors using aluminum parts. Plain water will turn aluminum into oatmeal. |
*Before installing the water pump, grasp the impeller with one hand and the drive hub with the other and twist to make sure the impeller is tight on the drive shaft. Not finding this problem beforehand can make you crazy. | *Before installing the water pump, grasp the impeller with one hand and the drive hub with the other and twist to make sure the impeller is tight on the drive shaft.
