Reply to "Radiators?"

I have an aluminum radiator on my 2002 GMC truck. I had to replace the radiator a couple of years ago. It wasn't the aluminum, it was the plastic end tank the failed. I inlet pipe on the plastic tank cracked.

Why do aluminum tanks on production vehicles have better survival rates? They are driven more, as daily drivers and in general and don't tend to sit.

Here's a a way to lessen the affects of galvanic action - disconnect the battery whenever the car is parked in the garage.

Fluidyne said to ground the radiator. I don't know if they still say that now but if you want to promote galvanic action, giving it a good path to ground is definitely the way to do it. Also, I am told Fluidyne now includes a bottle of Norosion their new radiators. I don't know if it's still true but at least it sounds like they are starting to listen to the complaints. They should probably also fire their tech support.

Regarding the laydown kit, I used one on my car even though I didn't have hood vents since my friend installed a laydown kit on his car without vents either but he had a different aluminum radiator setup. No problems with the set up on my friends car but mine wouldn't cool, even at freeway speeds. Hall has a 45 degree radiator that might work better for me but I can't recall if it's brass or aluminum.

Well... en.ough ramblings from me
