Welcome to DieselPlaceJust bought my 2.8l duramax canyon slt. Trying ro get a build sheet and dind out more information on a dtc for emissions stating a warmup timer expired requiring service. Also where can i find the block heater connection? Im told by my dealer it has one but the connection is not readily seen anywhere. Thanks
For finding a build sheet on your vehicle I would visit your local GM dealer. They should be able to print out what you need.
Usually, GM will tuck the Block heater cord connection up behind the headlight or close to the battery. Look in those locations.
