Hi Jeff. You shouldn't have to disconnect batteries for four months of storage, but it's probably a good idea to do it anyway...just to be safe.

SOURCE: 94 GMC truck diesel starts,runs and then dies and will not start

I have the same problem and have trouble codes 35 and 36. I found out that there is a computer module that needs replaced as it sits low in a valley and gets hot and seperates. I am reseaching about the a/m fix that installs the new module away from heat.

SOURCE: replacement of water pump on 2004 gmc sierra

Remove or disconnect the following:

Air outlet duct Coolant Inlet radiator hose from the water pump Upper fan shroud Cooling fan and clutch assembly Drive belt Radiator outlet hose from the coolant pump Surge tank hose Heater hose Water pump

0996b43f802030d1.jpg

DO NOT use cooling system seal tabs (or similar compounds) unless otherwise instructed. The use of cooling system seal tabs (or similar compounds) may restrict coolant flow through the passages of the cooling system or the engine components. Restricted coolant flow may cause engine overheating and/or damage to the cooling system or the engine components/assembly.

Install or connect the following:

Water pump. Install the water pump bolts. Tighten the water pump bolts first pass to 11 ft. lbs. (15 Nm); tighten the bolts final pass to 22 ft. lbs. (30 Nm). Water pump drive belt pulley and bolts (if applicable). Tighten the pulley bolts first pass to 89 inch lbs. (10 Nm); tighten the bolts final pass to 18 ft. lbs. (25 Nm). Surge tank hose Heater hose Outlet radiator hose to the coolant pump Drive belt Cooling fan and clutch assembly Upper fan shroud Inlet radiator hose to the water pump Air inlet duct Coolant

SOURCE: location of blower resistor for 2005 GMC sierra

Hi, the blower module that is located at the bottom of the heater box, next to the blower motor, above the panel below the glove box, has a tendancy to go bad, possibly overheat, and melt the larger of the two connectors. This can lead to one or all sppeds inop. the module will need to be replaced, and th connector inspected. If the connector is melted, or discolored, it needs to be replaced. A pigtail with wires, and connectors, as well as the resistor, should be available at a local GMC or Chevy dealer. Good luck...Coop

I need help in changing headlight bulb on 2008 gmc sierra 2500


You have to remove the air intake filter and then kind of reach around up in there to change it. It can be done, but is a lot of work. On the duramax, it is even harder to do the driver side because of the dual batteries. You have to remove the battery, then the battery seat plate, and undo the winshield washer fluid tank and lean it forward. Then you can just sort of reach in and change both headlights. A very big pain to change a couple of headlights, but if you want HID's.... for the average person, changing a headlight now means a trip to that garage.

How do I change the fuel filter on a 2002 gmc sierra duramax deisel? And where is it located?


becarfull, the fuel filter os on the passenger side of the engine compartment. after replacing the fuel filter you need to prime the system to get all the air out of the fuel system otherwise the engine will crank and crank and never start. if this happens, you'll need how to prime the system or tow the truck to the nearest Gm dealership.
read the owners manual for help.

Location


Right on top in the middle between the alternator and A/C compressor. The back t-stat has little vent holes that need to go towards the rear of the engine.

Can't find Nav fuse


I have a 2008 GMC Sierra 2500HD Duramax and use the HyperTech software also. I assume you are talking about the installation instructions for HyperTech where it tells you to remove the ONStar and Radio fuse. Look in the owners manual for the fuse box layout under the hood. On mine, it's in the Duramax book and the only fuse that applies is the one listed for the Audio System. You will need to reset your clock when finished.
