My Cerb dropped quite a bit of coolant over the garage floor this afternoon and I had noticed some tell-tale flicking of the temperature gauge. So, I thought, I'll do the right thing and bleed the system when I refill.

But... when I came to loosen the brass screw on the radiator it just span in place. When I eventually pulled it out what I had on my hand was both the screw and the thread it fits into, leaving just a smooth round hole in the radiator body.

Does anybody know how I can fix the thread back in place - I don't think a bit of used chewing gum will be up to the job ? Ideally I'd like to avoid removing the radiator or driving the car without any coolant of course.

P.S Looking on the bright side it didn't happen when I topped up just before my RideDrive day yesterday. Which is nice.

The best solution would be to tap a larger diameter thread into the hole, Just go up a size ie M10 to replace M8 use a bit of grease on the tap to retain the swarf and fit a larger bung + sealing washer etc and away you go.

Nice idea but the radiator is too thin to take any sort of a tap.

The car has gone in to the local dealers now so they can track down the coolant leak and hopefully fix up the radiator bleed screw too. Hopefully not a big job with a lift and the right tools.

I'd be inclined to bond the bleed screw back in place and tap through the centre of it to take an M8 bolt and copper washer .. works a treat on the cerbera sump bolts that are fitted by hamfisted dealers YOU KNOW WHO YOU ARE!! CURSES!

It was the "bond back in place" bit that I was curious about. Solder ? Glue ? Sticky-back plastic ?

chemical metal ( a two part resin and hardener, like body filler) is a wonderful thing ..

The nice AA man who repaired my fuel line split used this to fix the bonnet stay back into place after it fell out of its hole in the bonnet...bloody marvelous stuff Think I will smear it over the leading edge to stop the paint chips on the bonnet, shame it doesnt come in yellow
