How To Change High Pressure Rear Ac Hose On 2007 Chevy Tahoe

• #i

I have an 06 Tahoe Z71 and noticed my AC wasn't blowing cold. Establish out all the freon leaked out due to a leak in the smaller diameter line in the rear by the rear passenger tire over the beam. Anyone accept this result before or replaced any of the rear AC lines? Merely was wondering what was all involved.

Smaller line is your high side. Never had any of the lines leak on any of my 4 K chassis. Once yous remove line make sure y'all lube all sealing o rings with compressor lube oil. The system volition have to be pumped down with a vaccuum pump and leak checked then charged with proper amount of R134A refrigerant. There will be a sticker underneath your hood that shows the proper weight of refrigerant in the system.
Since yous have the arrangement already open now is a good time to go ahead and alter the orifice tube which is essentially similar to a jet in a LP/Natural gas furnace or oven. They dont look the aforementioned just do the aforementioned matter. It is located right in between your high and low side schrader valves. There is a big fitting right on the metal line between the schrader valves. But unscrew that and pull the sometime orifice tube out and supervene upon with new.

Heres a video on where it is and how to get it out.

Smaller line is your loftier side. Never had any of the lines leak on whatever of my 4 M chassis. One time you remove line make sure you lube all sealing o rings with compressor lube oil. The system volition have to be pumped downward with a vaccuum pump and leak checked and so charged with proper amount of R134A refrigerant. There will exist a sticker underneath your hood that shows the proper weight of refrigerant in the organization.
Since you have the system already open up now is a good time to go ahead and modify the orifice tube which is substantially similar to a jet in a LP/Natural gas furnace or oven. They dont look the same just do the same thing. Information technology is located right in between your high and low side schrader valves. There is a large fitting correct on the metal line between the schrader valves. Only unscrew that and pull the quondam orifice tube out and replace with new.

Heres a video on where information technology is and how to get it out.

Cheers. Is it mutual for the orifice tube to go bad?

Thanks. Is it mutual for the orifice tube to go bad?

The screen that is attached to it collects debris from the arrangement. Nether normal wear and tear information technology volition collect metal that is from the compressor as it wears. Information technology kinda acts like an oil filter. They are inexpensive. Run around $5-$10. Whatsoever auto parts store will have the i yous demand.

I had this problem. Line corroded where the bracket holds the ac line to the frame. Gm ready is to replace the bad section and splice the line from where information technology's good. Non cheap and probably be in the aforementioned problem 5 year later on.
What I did was supercede the rear ac line with a rubber hose associates. Ran the line next to the old ane and attach it to the front ac line meets.

Replacing the accumulator is a must if you have a leak or if Any moisture is introduced into the arrangement. It has a desiccant handbag that collects the wet in the organization considering the moisture will cause acid and consequence in a failed component. I'd go ahead and alter out the loftier and depression side service port valves while you take the take chances too.
