I was just wondering if any of you have the same problem.... when I bought my car the temp gauge didnt work until I drove the car for about 20 minutes.... then over the winter I did a heads and intake swap.... so I put in a new temp sensor and sending unit.... So I would imagine that stuff is good to go... I also put in a 160 thermostat, so I was wondering if maybe the car isnt heating up enough to get the gauge to register?... or maybe something else is messed up?.... thankyou for any all all feedback.
