Reply to "heater questions"

Part of my last engine replacement was to remove the heater tubes and install new ones. I would never do it again. The central spine of the chassis was welded around these pipes. I cut holes through the console framing at the anchor points only to find that there are two metal surrounds that have to be removed. After the better part of a day I finally had the tubes loose only to find that the bends prevented removal. I ended up cutting one tube to get it out. I replaced the lines with 5/8" OD refrigeration copper tubing. Why did I do this to begin with? Well the ends of the tubes appeared to be corroded and I was afraid that they would eventually rust through. What I found was that these are a very heavy wall thickness and would probably have lasted forever. Running separate lines under the car may work but there is not a lot of spare space under there either and since my condenser has been moved to the front most of that space has already been used. Good luck if you take this on. I would recommend leave well enough alone and if these lines ever corrode out close your isolation valves and deal with it only when forced to.
