Anyone Try J.B. Weld On Front A/C Condenser?
 

I was wondering after hearing so many stories of JB weld fixing boiler pipes and other things if it could fix the hole that I have in my front A/C compressor on my 88 Carrera that I got from bottoming out?
Has anyone here tried it?

Thanks

I doubt it.
Remove it and take it to a radiator shop. They may be able to fix it.

I can't imagine JP weld holding up to that much pressure and heat. Now is a good time to just replace it with a higher performance unit.

It's the bottoming low to the ground front that's the problem, not as new higher performance one. Maybe a new titanium box for the condenser?

Radiator shop, plus two.

Pretty inexpensive if you remove it from the car.

Radiator shop is the way to go BUT

I used JB Weld to repair my sterilizer in my dental office.

There were four small pinpoint holes that at 265 degrees Fahrenheit and 15 psi would leak and allow steam to escape out.

I cut two small square strips of aluminum, bent it to conform to the cylindrical sterilization vessel, coated the underside with JB Weld and put them against the inside of the sterilization vessel.

The MAIN advantage is that at 15 PSI the pressure presses against the aluminum and seals the holes. The JB Weld probably holds the strips of aluminum in place rather than mechanically plug up the holes.

I also have the advantage of being able to visually inspect the aluminum, I'm with the group, take it to a radiator shop

Can i use JB Weld for fillings?

HA ! I wouldn't recommend it. When you mix the catalyst and base it will create an exothermic reaction (heat) which may negatively affect your nerve. But I've seen some pretty weird stuff in my time. Maybe that's a thread I can start over on the Off Topic forum

"Weird Stuff I've seen in teeth" :eek:

The "Dental Fix" won't work with a condenser; you can't get the patch INSIDE the condenser like with the sterilizer.

Even if you got the JB Weld patch to work, it probably would be short lived. Your biggest problem is going to be getting the surfaces clean. Then you might even have some charge (Freon) left in the system which could contaminate the patch even after you've cleaned the damaged area.

I think it's a losing proposition, take it to the radiator shop, or like its been said take the opportunity and up grade the condenser to the newer serpentine style.

I would go with the weld repair, BUT if ever you think of JB Weld for patch work consider MARINETEX instead. Its a two part epoxy that is used to fix engine block cracks! The stuff is incredible. It comes in a white box, mostly sold at marine stores and is outstanding for patch work. Its JB Weld on steroids...........

Don't use JB Weld on anything that builds pressure such as a condenser or intercooler. They sell those front condensers in the OEM replacement model or those aftermarket ones.

Do yourself a favor and start with a fresh one, that way it will flow better with cleaner cooling fins.
