SSM 48601 - 2015-2019 Transit - 3.2L Diesel - Loss Of Power During Driving Under Extreme Cold Weather Conditions
Some 2015-2019 Transit vehicles equipped with a 3.2L diesel engine may exhibit a concern about loss of power during driving under very cold weather conditions. This may be due to fuel waxing/gelling in the filter. Market fuel properties or improperly adjusted seasonal fuel may lead to early fuel filter waxing and restricting fuel flow to the engine. In order to rectify this extreme cold concern, a fuel filter thermal valve kit CK4Z-9B337-B can be installed. The kit improves the recirculation of warm engine return fuel inside the fuel filter to reduce waxing. Instructions on how to install this fuel filter thermal valve are contained within the kit. This is a customer pay upgrade only and not covered under warranty.
