Heat is a major consideration in a new engine. Do not allow the engine to
overheat. Although the heat indicator on the instrument panel shows the general
temperature of the engine, it will not show a sudden rise in temperature of an
individual part.
The pressure imposed on parts such as bearings and pistons due to rapid
acceleration or hard pulling will cause them to overheat if the car has not been
driven sufficiently to break them in. Avoid fast acceleration and hard pulling
while breaking in.
High speed also develops higher operating temperatures and to avoid damage
the car speed should be kept within the following recommendations:
0-250 MILES
Do not exceed 40 miles per hour in high gear or 20 miles per hour in second.
Do not accelerate rapidly. Use second gear on steep grades. Keep motor
temperature within "driving range" on dash heat indicator.
250-500 MILES
Do not exceed 50 miles per hour in high gear or 25 miles per hour in second.
500-1000 MILES
During this period the speed should not exceed 60 miles per hour.
Do not UNDER ANY CONSIDERATION attempt to maintain a high rate of
speed unless the crankcase is full of good oil, and until the engine is thoroughly
warmed up. Cold oil is not able to flow freely into the small clearances between
working parts so that damage may occur if sufficient time is not allowed for
warming up before attempting high speeds.
