I am using a 4 cyl thermostat housing on a 3.4 doch swap. I cut the flange off and I am trying to weld a section of 1 1/2" pipe to extend the housing to clear the throttle cable.
I cannot get the weld to stick very well to the thermostat housing, only the pipe. I have read some posts where a few people did weld to the housing. How did you do it?
That makes sense. It did look like the joints were copper or brass.
Yeah, it might be easier to just take them to a shop for brazing.
If you're willing to try it, I used a little oxy/map gas rig I picked up at Home Depot. It's not very expensive and gets the job done. The tanks don't last long, but it works.
