Whenever you read the manual, any job on the engine, front suspension etc always starts with the phrase "first, remove the radiator".

The logical extension of this is that the last step of any job is to put it back in.

So it is with great trepidation that I put it back in and connected up all the new hoses.  I just know that I'll end up having to take it out again, which is why I've prevaricated so long.

Anyway, it's done.  I haven't filled it with coolant though...
