Cooling system question

As you may know, I had the 67's radiator fixed and all of the radiator hoses replaced in the engine compartment. The next step in the project was to have the rear heater looked at and replace the hoses that connects it to the main radiator.

Last weekend, I removed all of the hoses and took the rear heater core to the radiator shop. They cleaned it up and am ready to put it back in the car.

I also repaired the fresh air intake assembly. The only thing missing is the heater motor that should be repaired within the ext 2 weeks.

The next steep is to run the hoses from the back to the front. Where the hoses transition from the wheel well area to under the car, they are joined by coper pipes that go through at 90 degrees elbow through the floor.

I also want to replace these coper pipes, so my question is does the regular led that one would use soldering withstand the heat of the hot engine water?

If not, what would you suggest that I use to solder these pipes together?

Thanks,
 
the lead solder will do just fine. no need to go to silver solder on that. remember the car only gets up to just past boiling temp. :thumb:
 
The copper lines are probably as good today as they were on the day that they were installed. I see no reason to mess with them. I would visually check them for damage where they come in contact with sharp edges. If everything is good, then I would leave them alone. There is a better chance that what you install today will not be as good a quality material as what was originally installed.
 
Thanks guys.

I will remove the pipes this weekend to see what they are like.

Of course, where there was once a tight fitting hole for theses 2 pipes to go through the floor, there is now a big rusty hole. That will also need to be fixed.
 
from the ones I have see they were a s shaped double set soldered to the plate. then they chopped a hole in the floor and ran them threw. to me it was a invitation to a rust spot and 4 more splices to leak. but that's the way they did it. the others I have worked on used holes threw the floor with the rubber grommet. most of them the rubber was missing. but I'm with Paul on using the original set up. unless you can see were it has started to brake down. butr the whole set up is not good. the circulation is so poor from the t's and the cut off valve that the sludge builds up on the lines and plugs them up. haven't seen one yet your could not get a gallon of rusty sluge out of when you flushed it. my limo included in that.
