[urq] Radiator cap-off

I'll be using a 4kq lower rad hose I think - one that eliminates that branch 
to the aux rad anyway.  I bought one and it look like it basically matches 
up - the angle of the section that connects to the t-stat housing seems a 
little different...

I just need to cap of the two upper fittings on the rad...

looks like I'll use a copper cap inside a very short section of tubing for 
the big one - suggested by a couple Listers.
