how to install a aluminum radiator? ??

[rebelcuda73]

I just received my champion 3 core radiator which I am I stalling In a 74 cuda with a 68 440 and a a833 trans. I've test fit the radiator and it fits perfect using the original bolts and holes. The only things I am not sure of do I need to use rubbber was hers behind the mounts against the frame of the car.  Also saw a article that said do not run a ground wire to the radiator because it creates a path for electrolysis. It also said use regular tap water not distilled and  to use a g5 type anti freeze especially formulated for different metals. Also use a anoide installed in the cap to protect against corrosion.  Anyone read up or  have any experience with this?? Want to Install correctly.  Thanks

My take on this is all alum rads are mounted with isolators from the factory , alum will not withstand flexing for long but people want plug & play so the rads are made to bolt in , any flex you can allow will help the rad live longer . I was always told to use distilled water in cooling systems to decrease the electrical transfer & keep the rad & system cleaner yes use a modern AF for compatable with alum

Basically aluminum is a great conductor of electricity so any bad ground on the frame means you will transmit that through the coolant which is bad. Why not kill two birds with one stone and do what Brad did and utilize rubber mounts to prevent that nasty voltage causing corrosion and also prevent the radiator being torque twisted by a big block.
