Vacuum hose location

I need to find a vacuum hose location on my 2007 Silverado 2500 HD 6 litre that I can easily access to attach a device. Everything under the hood is very confusing and I don't want to make any mistakes.

Do This - Reprogram the HVAC control module.
Don't Do This - Do not replace the coolant level sensor, HVAC control module or radiator surge tank.


A revised calibration has been developed to address this condition.

pretty easy job, facing the engine you will see the "fan shroud" you need to take this plastic cover, it usually a round cover that is halved so it has bolts on the side take the top half off and you will have access to the fan clutch which of course is located behind the fan

Sounds like a heater core. Check the passenger side floor board. Sometimes when these go out there will be some water on the passenger side floor. Hope this helps some.
