Starter motor not engaging in cold weather

This last week while hunting elk in Eastern Washington, the weather got down to about 30 at night. In the morning when I went to start the truck, the starter motor just spun but didn't engage. After the starter motor came to a complete stop, I hit the key again and it started fine. This happened twice on two different days, but only when the truck was covered with frost during a cold start. Anyone had this happen to them? Should I replace the starter or something else? Thanks, Don

Replace it, it wont hurt to do it. Starer sounds like it is going out.

Re: Starter motor not engaging in cold weather

sounds like you may have some hardened grease on the splines for the starter drive--and the solenoid doesnt have enough umph to push it--if remove starter--and lube the end of the drive with wd40--and hook batt to it --and hit it a few times to engage and disengage--may help to clean off the old hardened grease--so will work right again--

Re: Starter motor not engaging in cold weather

Your starter drive has a one way roller clutch in it. It has to have this so it will not overspeed your starter motor when the engine starts running. The clutch is probably slipping. Cold makes them more prone to do this. The fix is to replace the drive. These days most people just replace the starter.
