1st gen radiator switch

Post by Greeneunos » Wed Mar 13, 2019 6:32 am

Hi I have just replaced the original radiator with an aluminium one , it’s exact in every way and appears excellent quality, there is one issue , the original sensor for the water level warning which fits in the centre of the top of the rad is smaller in diameter than the hole in the replacement radiator, does anyone know if the sensor from a later model may fit ?
Thanks in advance if anyone can help

I think kiwiwdave had this issue also.
He got a new nut of the correct thread welded in place.

Find an ally nut that matches the OEM level sensor. The guy that did it for me welded the original location closed and then drilled another hole and mounted the ally nut on top. I don't recall what the thread pitch was but easy enough to find out. Any hardware store will be able to tell you.
