Hi all,

I'm doing the cambelt (the full works) on my Blob on Saturday and I'm replacing the radiator at the same time as the top plastic end tank is weaping.

I'm replacing it with a full Alloy Radiator, do I need to earth the new radiator? I've had a google and there are a lot of conflicting reports!

Cheers,

Never heard of anyone earthing a rad, it sits on rubber mounts

Ive just fitted an alloy one to mine, no earthing required. Just a trim of the hoses as a bit thicker.

As above..why would you want to earth a radiator.

To stop electrolysis.

dazsti72

Never known of that mate but just googled it and I see what you mean.
I suppose it wouldn't harm to earth it in that case.

Eh? Lol engine is alloy and so is the origional rad, just the end tanks are plastic so earthing a rad is a waste of time

But engine is earthed.

The engine is earthed so the starter and all other sensors work.

Electrolysis can only occur if the radiator IS grounded, otherwise the radiator will remain at the same electrical potential as the engine block, assuming the coolant is acting as an electrical conductor.

This could only happen if you have an electrical component in the cooling system in a fault condition ( allowing voltage to leak to earth), which should blow the fuse anyway.

I wouldn't worry.

Yes i know but being earthed would help prevent electrolosis.
