UI Bulletin #117 Subject: Improper Engine Block Heater (Option K05) Usage - Continuous Power Models Chevrolet Express Cut-away Vans Affected: Chevrolet Silverado Chassis Cab GMC Savana Cut-away Vans GMC Sierra Chassis Cab Upfitted as an Ambulance (YF2) Model Years: 2003 and beyond Date: July 16, 2014 Revision July 16, 2014 Date: ADVISORY: This bulletin refers to General Motors Service Information Bulletin (TBD) – GM Dealers should refer to the bulletin for more information. Condition/Concern: General Motors has identified vehicles with the optional Engine Block Heater (Option Code K05), standard on all Duramax Diesel engines, where the fleet customer, dealer, or secondary vehicle manufacturers/upfitters have plugged the engine block heater into an onboard “AC” power source providing continuous 110v power to the heater resulting in electrical failure, shorting of wires, overheating of the system, and possibly engine compartment fires. Specifically, fleet customers, dealers, and secondary vehicle manufacturers/upfitters for ambulance bodies are reminded that the Engine Block Heater usage is only for inclement weather conditions specific to assisting with cold weather starts – not for continual usage or usage during non-cold weather conditions. Repair/Recommendation: As shipped from GM, the available Engine Block Heater Cord is furled up and attached under hood as illustrated in Figure 1 (item #2 & #3). Fleet customers, dealers, and secondary vehicle manufacturers/upfitters are reminded that the Regular Production Option (RPO) K05 Block Heater is to be used for Intermittent Cold Ambient starts when the outside temperature is between -18 degrees C (-0 degrees F) and 29 degrees C (-20 degree F) – not to be continuously plugged into an “A/C” source.
