Evaporator DIY possible?

[fusionrx]

Got leaking refrigerant, don't see any visible leaks externally, mechanic thinks it might be internal leak, and mentions Evaporator core as a possible place that they suspect.

Are there any other places it might be coming from? Can this be done as a DIY type job?

See there is a kit available online: http://www.eeuroparts.com/Main/PartD...x?id=400111308.

Everything seems very expensive. Are there substitute OEM brands that would work in its place?

check valves and condenser condensers get hit by road debris alot. Evaporator will need to be cut with a pipe cutter removed and replaced and re-sweated together this is not a bolt in part. If you can plumb copper you can plumb the evaporator in it's not too hard, just scratch up the surface good put a little welding lube on the pipe and hit it with the torch with the solder against the edge of the joint, you will see it seep inside and under if you scuffed the pipe up well enough, if you don't than it is not sealed, its not like welding a seam you want it to soak into the fittings space to make a long thin flat sweat around the inside of the fitting.

I think this kit... http://www.eeuroparts.com/Main/PartD...x?id=400111308
makes is possible to install without soldering any joints, but you will have to cut the old one out- or bend the pipes enough that it will pull out.
