i would not be doing that. maybe look at an SPi rad that has a suitable hole already in it.

 

plastic and drilling holes and then pressurising it.

Nick it is a plastic rad, I intend to bond on another piece of plastic to thicken the wall where I intend to drill & tap the bottom tank

 

 

Whoa !!! They are dreadful things.

I'd suggest fitting a proper Brass / Copper Radiator. The one that was in your car when it left the factory would have had a Drain Plug like this

I've always been able to reach the bottom hose clamp with a long screwdriver. Then just remove it. Simples.

That stays there if you ain't lifting the motor

It's not the removing it I was worried about  -  it's the getting it back on!!     My hand definitely won't fit down from above!    When I get round to replacing the coolant  (after various other jobs)  I might see if I can reach it any easier from below.

If you remove the fittings holding the radiator you are able to manoeurve the radiator enough to give you better access to locate the bottom hose.

 

When replacing the coolant I usually remove the radiator anyway to flush it out and clean the fins etc.

 

When reassembling the cowl, radiator fittings etc, I cover the delicate metal of the fins with a piece of card to prevent the fan from damaging them whilst repositioning every thing.
