SOURCE: location of block heater cord on my 2003 chevy silverado

MIne was on the passenger side inside the wire loom next to the shock. You can get to it through the fender well. It just looked like a ball of tape and only the plug itself was exposed with the rest of it doubled back on itself inside the loom. It was actually long enough to stick out of the front of the truck.

If it has the block heater, the heater is located on the drivers side center of engine block. You should be able to crawl underneath, and see where the heater is put in place of a freeze plug, and just follow the wires up.. Usually tucked in along the fender somewhere..

Where do you plug in a2003 chevy 2500 diesel when it is going to be cold


If you have a block heater, there will be an extension cord type plug somewhere near or under the front grille (sometimes you need to find the heater and follow the wire to find wherever it got tucked in) That gets plugged into an extension cord from the house power.

2003 Chevy needs transfer case replaced for the 2nd time


I just had my transfer case rebuilt on my 2002 2500 silverado duramax. They told me that the spring that holds the pump inplace in the transfer case wore a hold through the case. He said this was common on these transfer cases. Chevy has not acknowledge the problem. He designed a steel plate, with flanges that holds the pump in place and will not wear a hole in the case again. And as far as the post to engage it once a month, the chain turns even when in 2WHL drive.

Low fuel rail pressure


who did a conversion on this truck???? the duramax is a common rail engine and can not handle wvo or sve. it will destroy your entire fuel system in no time on this truck. if you want to do a vo conversion you need to get a diesel with an inline injection pump or one of the older powerstrokes. i would suggest you quit trying to run wvo through this truck if you do not want to do a lot of very expensive damage

Block Heater not working


There is no fuse on a block heater. It is an extension cord with a resistor (element) on the end (see photo. If it not working, the resistor (coil) has failed. A new block heater is required.
Before replacing, however, check the outlet and/or beaker the outlet is on to see if it has tripped.

I want to change a block heater cord


Hello
If you have a frost plug type heater the cord does unplug from the unit.
if its a in line hose type heater chances are you wont be able to replace just the cord.
