I have a Mk1 Golf. The previous owner has put in the 3 GTi console gauges but didnt connect them.
I want to connect up the water temp gauge (which is the mechanical type with a heat sensing bulb) but still keep the original electric gauge working as well.
I was wondering if I could simply make a hole in the radiator hose and insert the bulb and seal it in.
Would having the bulb within the hose impede the coolant flow at all? Does anyone know another way of doing this?
(PS: diameter of hose is 30mm and length of bulb is about 25mm, and 8mm thick.
