winter squeeking noise
Odd problem, more annoying than anything. Each winter my 1998 4.0 liter ranger squeeks as the engine heats up in cold weather. During the summer, when the outdoor temperature increases, the squeek goes away. This has occured for the last 3 years. Over the years, I have replaced most equipment on the serpentine belt (alternator, water pump , power steering pump, belt tensioner, idle pully). Not the air conditioner compressor. The frequency of the squeek increases with rpm. Hence, not the trans. The squeek occurs with truck moving or still. Can't pinpoint the source of squeek. May be from the area of the crank shaft pulley. I'm thinking some metal may be contracted in the cold and other metal expanding as the engine heats up, causing a rub. The squeek sometimes goes away after about 30 minutes of travel, perhaps after all the metal heats up. Does anyone have this problem or have a suggestion?
