Radiator thermoswitch

[Colesy]

Spent most of today changing my cracked radiator for a new one.

To keep things short and sweet things went something like this:



It was a hell of a job, I've managed to swap the radiator in after a long afternoon of squeezing, stretching and swearing.

Everything looked fine. But, I've noticed that there is a bit of a leak around the thermoswitch, I didn't tighten it too much as I don't want to break the new rad. I didn't notice a washer but the old one might have just been caked in limescale and stuck.

So what can I do to ensure a good seal?

Cheers for any help.

It should have a washer...

PTFE tape around the thread and a smear of silicon sealer on the back face that contacts the radiator

Yes it should have a washer but can still leak even if you use one without silicon.

I quote this solution!
had the same annoying problem on my RS2 and the advise from johne it's the right trick.
Otherwise there's a good chance to spoiled a new radiator (my case)

Thanks for the replies guys. It seems to have sealed it's self after a couple of heat cycles! I'll keep an eye on it though and if it leaks at all I'll be buying some PTFE tape!
