New leak- gx470

[AdamKFarmer]

All the freon has leaked out. Not sure why you don't replace the hose? JB weld will not last. Most likely you'll need some compressor oil in there as well. I'd replace the hose and take it somewhere to refill. Loosing the JB weld you're knowingly adding r134 to the environment which is not great.

This is also what I would do. Maybe even pull the A/C fuse so you're not running the compressor without oil after repair. Also with respect to you having rear ac, it would affect the size of the system as a whole, more freon, larger system etc so the geometry might be different from the smaller non-rear A/C model. As far as it being different from a standard plumbing job, it's not. Just replace the o- rings on all the hard lines when you replace.

Also, I should say. I've refilled a few systems before. It's not difficult, all you need is a scale, the manifold and the correct type of freon and oil. The trick is to not overfill it.

There are two compressor options.

There will be sticker under the hood that will have the detail on how much freon the system needs. Likely will be somewhere between 20 and 30 ounces. A couple of cans of freon should be enough.

For the replacement hose, ideally you can grab one from a junk yard. I've dealt with this on front end damage and grabbed junk yard parts that have held up just fine for AC. Of course, there are way more Tundra's/Sequioa's in the yards than GX470. Once you have the right part number, check to see if it crosses over to one of the other 4.7 2UZ-FE platforms. You might luck out and find it is not a part specific to the model and readily available.

Your JB weld repair may (or may not) hold up. You will be better off replacing the hose. It is as simple as you would think and only as complex getting access.

I have JB weld on mine after my dad nicked it with the cutoff wheel on the angle grinder when installing my front bumper! Still holding strong after 5 or 6 years!

Definitely the AC line, high pressure side. It was resting against the winch cradle of my front bumper, which eventually wore through the rubber coating then wore a groove into the line itself. Moving the line around would allow the fluid/gas to escape a little easier than when it was pressed against the cradle... here I made you a little video....

And what a delightful project... to try to gain access I removed the a nice portion of the front end of the vehicle. but even with that there was no way I could fit any of my angle grinders into that space, was hoping to notch that out somehow. You can see where it was rubbing into the AC line, and the cut that was produced.

I see, that makes sense. So the refrigerant hadn’t all leaked out yet. Well that sucks! Interests to hear if the jb holds. I too have a gauge set and vacuum pump if you decide you want to try it.

@nakman - I left you a VM. Happy to help. AC is easy. Just redid my system

Ok thanks for all the support here... I got a little inspired by Adam V's post above, and went out and squirted some new juice into the system.. had cold AC for a minute, but then the hiss ensued, I guess the JB weld didn't hold this time. Not sure if it's the added pressure from that side, or maybe my JB weld was just old, too cold, etc. 1-2 now, ftr.

So I'm ordering the hose. Will pick this up again once I get that installed, figure out how to get it all filled up again. also pulled the AC fuse for the time being, thanks for that, as the defroster is likely going to be kicking on before this is fully repaired.
