radiator question

Post by hiluxmad »

is there any common issues with running an alloy radiator on a holden v8 engine?
cast heads and alloy radiator?
putting one into my lux and trying to work out which way to go to get the best cooling.
Keep it shiny side up!
Now doing general fab work and painting
trays, trailers, engine swaps on request, some tube work, silo section sliders, rust repairs, ute chops etc

Set up properly the radiator should have no electrical connection to the body... ie rubber mounting all round, no metal to metal.

If you do this right there's no electrical/corrosion issue.

Just our of curiosity how recent are holden v8s with cast iron heads?
This is not legal advice.

its a vn injected motor i assume they are still cast then? they are definatley not alloy.
one option is to use the hilux rad and recore it but if i use an alloy version it is bolted to the body so it would have an obvious conection to the body electricly speaking.

No idea, I just don't know those motors and I kind of assumed they would have been alloy for a while.

It shouldn't be bolted to the body directly no matter what kind of heads you have... at least that was always my understanding.

the hilux ones are directly bolted to the rad support.
