Coolant gauge issue

Wilson2608

Both of you are obviously very knowledable about cars/ electrical work, and i basically know little to none about this kind of stuff. But im adament about doing the work myself for the purpose of becoming more educated. When my engine blew in my 300zx I took it upon myself to do a motor swap. It took me like 2-3 months, but eventually i got it perfect with no issues at all. And now i could do it in half that time, and thats the reason I want to fix this issue too. I will follow the procesdure in the FSM so I don't mess anything up and i'll let you guys know!

Thanks so much for help mates
