Where the radiator neck & the hose meet, there is a wire thermo fan sensor that slips in between the hose & neck. I can't get it to seal & leaks under pressure. What can I do???? HELP!!!

Get one of these and cut it in half then sort of twist it around the sensor wire and then clamp the hose. I used this on my car and it worked perfectly.

The wire sits in the groove and the rubber piece sits between the radiator outlet and radiator hose the clamp of course goes over the hose and clamps them all together.

When using Silastic for any joint clean ALL surfaces with methylated spirits and clean with paper towel. Repeat met

Then I ran the wire from the mechanical setup to the new sensor and everything is working fine.
