GM Heater Outlet Hose Assembly, 2001-2004 LB7
Fits: 2001 thru 2004 Chevy Silverado/GMC Sierra 2500HD/3500HD LB7 Duramax Diesel
This is the outlet hose(passenger side) from the heater core. The plastic fitting and hose can leak over time due to age and heat. They are also known to have very small unnoticeable leaks that are usually burned/dried up before you notice it. When the plastic fitting becomes brittle and breaks it can lead to an overheating issue. We'd recommend replacing it even if it doesn't seem to be leaking and it is the original part. Some of these parts are going on 20+ years old so make sure to replace it with this low cost OEM replacement part and arrive to your destination with no hiccups!
