Otter switch problem

[killergoat]

Hi there,if anyone can help it would be much appreciated. ive a problem with the otter switch on my 1977 taimar :furious: well the thing is leaking. On closer inspection its very loose in the radiator and is not screwed in but just slides in wth nothing to secure it tightly.

Please help :rotate:

Well thanks everyone for the advice.
Your right Davidy, thats seems to be the best thing to do, get rid of the original otter and plug the hole.

Cheers
