Reply to "Heater tube replacement"

Once you make the difficult decision to R & R the heater pipes in the car, it's advisable to begin using some sort of anti-corrosion fluid in your cooling system. One East Coast owner DISSOLVED two new aluminum radiators in 1 yr with his local water. Luckily, Fluidyne warrantied both assembles... They now include a bottle of No-Rosion with every radiator sold, and recommend its use.
Once you decide to replace the old pipes with ss, remember you need not actually remove the old mild steel pipes. You can run new ones alongside the old with less trouble than digging the old ones out. They do not need to be bracketed as substantially as the stockers. You can also replace the two short, failure-prone rubber heater hoses with compression fittings or ANs at the same time, to eliminate yet another potential problem down the line.
