Difficult Cold Start

Problems

Several things could be causing difficult cold starts for your Caterpillar Semi:

Cause: Stiction

Solution: Treat the engine with the Stiction Eliminator, and run it for one full oil change interval.

Cause: Poor fuel quality

Solution: If you suspect poor fuel quality, treat with Diesel Extreme. In winter, treat with a half-dose of Diesel Extreme and a full dose of Diesel Winter Anti-Gel.

Cause: Glow plug problem

Solution: Check the glow plug circuit.

Details

Low boost when the truck is cold could be caused by stiction in the turbo bearing. Treating with our Stiction Eliminator should clear this out. A problem with the grid heater could be something as simple as corroded battery cables, making the heater not work at full capacity, or it could be a complete failure of the grid heater.
