Where is the EGR valve on a Duramax?
Over time, the EGR valve will clog and will need to be replaced. Disconnect the cable on the negative terminal of the battery. Locate the exhaust manifold on the engine. The manifold will be on the right side, or driver’s side, of the engine, but its location will vary slightly depending on the particular Duramax model.
What kind of valve system does a Duramax have?
Duramax diesel engines are installed on many of General Motors light and medium capacity pickup trucks. The engines are all equipped with an EGR valve system, which operates by recycling a portion of the exhaust through the engine.
How do you remove an EGR valve from an engine?
Remove the EGR valve from the engine by removing the Torx bolts that secure it. Place the new EGR valve into the same position as the old one and secure it with bolts.
Where is the exhaust manifold on a Duramax?
The manifold will be on the right side, or driver’s side, of the engine, but its location will vary slightly depending on the particular Duramax model. Locate the metal tubing that is connected to the exhaust manifold. Follow the tubing to its other end, which will be connected to the EGR system.

How long does it take to replace EGR cooler?
FWIW, Alldatadiy says it’s 3.0 hours to replace the EGR valve, $323.58 for the EGR valve, dealer list. Additionally, they say 3.1 hours to replace the EGR cooler (EGR valve is attached to the cooler), so maybe 6 hours to pull the cooler and valve, replace the valve on the cooler, and reassemble. This would be for a 2008 2WD.
Where is the EGR cooler bypass valve located?
An EGR valve is a totally different animal than an EGR cooler bypass valve. On a LML engine, the EGR valve is near the front on the left side, it has a brown connector with a yellow retainer. The cooler bypass valve is at the rear of the passenger side, almost can’t see it below the cowell, but has the same style connector plugged into it.
