90's Suburban Duramax Conversion
Member Gordon Marks has been hip deep into converting his late 90's 2WD Suburban to Duramax/Allison these past few months. He's getting real close to finishing it, and has already run the engine. We thought you might like to see a couple photos.

Diesel vs. Gas Rear Heat Valve
We're in the process of converting a 1999 true half ton suburban gas to 6.5L diesel. So when we go to the parts book, we say we have a '99 1500 4wd Suburban with a 6.5L. We know that they may be looking at a rig with 8 bolt wheels, but we should be ok for what we need. To make a long story short, our gas Sub had a wire driven, vacumm valve that appears to either control hot water flow (or simply on/off flow) to the rear heater. When we ask the gm parts guys how the diesel works, they say there is no valve. They also tell us that the rear hvac box does not have a flow control valve. Can you, or anyone help us out as this doesn't make sense to me. Thanks!!
