SERVICE INFORMATION

TO: ALL CHEVROLET DEALERS

Customer comments of hard starting or no start conditions at very cold temperatures may be due to a slow cranking electric starter or to improper starting procedures.

Where low cranking speeds are determined to be the cause of poor startability conditions, a new starter should be installed. The new electric starter, P/N 94141664, is rated at .8 KW replacing the original starter rated at .6 KW. The VIN breakpoint for the new starter is F8425905.

The recommended starting procedure has been revised to include provisions for very cold weather conditions (below -10 DEG F or -23 DEG C.) At these temperatures, the operator should perform the following:

Before cranking the engine, fully push down the accelerator pedal three (3) times and slowly release it.
Push down the accelerator pedal to 1/3 of its travel and hold. Crank the engine by turning the ignition key clockwise to "START". To prevent the engine from stopping after it starts, it may be necessary to release the accelerator pedal slowly for ten (10) seconds from 1/3 of its travel to normal idle. Additional warm-up time may be required to avoid the engine stopping upon shifting into gear. If the engine starts but fails to run, repeat Step #2.

NOTE: Do not crank the engine for more than 15 seconds at a time. Wait 15 to 30 seconds before trying again. This will prevent damage to the starter.

Use applicable labor operation for starter replacement.
