"Now remove the rubber gasket from the coolant tank cap and cut a slit from the I.D. to just beyond the cap’s inner relief valve." OR in another post it is worded, "and cut a slit that allows it to vent thru the center valve in the cap."
Not sure where I cut this slit? See this photo - by any chance, does anyone know if this is right? Or is it a cut inside the coolant tank neck?
I understand it's about making the cap non pressurised, so I think this would do it - just checking before I take the knife to it
Help appreciated.
