Model: Express 2500 Passenger
Engine Size: 6.0
Refrigerant Type: R134a
Country of Origin: Canada
Just talked to my father, his air doesnt work. He has a 2006 Chev Express Passener Van 2500 with a 6.0 Liter V8. I havent seen it yet, but wondered if there were any common leak points with this van.
Thanks for any info,
If you have rear air- and I'll assume you do---- look at each bracket that holds the rear a/c lines to the underbody- they tend to hold moisture (and salt - any salt in Canada?) and corrode the aluminum to the point that a leak develops- look for oil and green dye residue- (a black light at night really helps) especially in front of left rear wheel- The fix I use is to splice in swageloks- they work really well on the 3/8 high pressure line- otherwise you need to buy the expensive rear line set and jack the body off the fram to replace them.
The number one A/C diagnostic tool there is- is to know how much refrigerant is in the system- this can only be done by recovering and weighing the refrigerant!!
Just a thought.... 65% of A/C failures in my 3200 car diagnostic database (GM vehicles) are due to loss of refrigerant due to a leak......

Thanks for the info. Ya they definately use salt around here! I have an Astro that I have replaced rear lines over the years. I think this is the same, but still should be covered under extended warranty. It has rear air and rear heat, and I think the coolant line is leaking at the same spot where I think the A/C is leaking. Its going in next week.
It was a rear line. And its backordered for a week, apparantly there is no lines in North America in stock.
