I have a coolant leak which is coming from where my top hose joins the radiator. The leak seems to be coming from where I have run the thermocouple for my variable temperature fan switch (the blue edged dial) as in the following picture. I've tried to tighten the hose clamp as far as I dare in the hope that the hose would deform enough around the thermocouple wire, but to no avail.

Is there any reason why I could not use gasket sealant or that blue silicone gasket maker stuff? I could smear some around the thermocouple and the radiator hose connector before sliding the silicone hose on and clamping it down.

I suppose that for an even cheaper fix I could use some spare silicone bath sealant that I have lying around?


Description

Yes or alternatively cut a couple of sections of bike inner tube and stretch them over the stub pipe, then fit pipe and sensor and hose as normal.

I cant quite see what you are doing there but the cappilary tube with sensor looks very much like the Kenlowe I have on my Landy. There is a short length of rubber, shaped like a speed bump with a slot for the cappillary tube that fits in between the hose and radiator pipe, so when the hose is clamped, the cappillary tube is sealed.

Give me a moment and I'll see if I can find what I am trying to describe.....

here you go my little fluffy buuny

One of those speed bump things came with the switch and thermocouple, but it leaks far more when I use it than when I don't. Maybe its just not a very good one, but is doesn't seal well either where the thermocouple wire is in the channel or where it tapers to meet the stub pipe.

What about self amalg tape?
