SOURCE: I need a vacuum line schematic for a 2003 chevy
Replace the complete heater control vacuum line over the motor with rubber vacuum tubing.
The heater vacuum line connects on the drivers side of the engine halfway back on the intake manifold.Run the new line to the heater vac connection at the passenger side at the right front in the engine compartment.
I change 2 a week....this should be where your problem is.
Testimonial: "That took care of it. I did change from that small vacuum line to the large rubber and ran it up to a wire loom overhead so as not to get as hot."
SOURCE: Where is the egr valve located on a 2003 chevy 4.3
The EGR Valve is located on the front of the Engine under the frest air tube. It is at a 45' angle. When checking look for lodged carbon chunks. I recommend using a gesket with a screen built in. It is located infront of the Thermostat housing.
