So I have a 1970 dodge charger 440. Recently the coolant temp gauge went to full after 5 mins. 1. Engines not running that hot used a laser temp gun plus its 5 mins. 2. I did the old ground check to check for broken wire/guage and it checked out went to full when you grounded it and it went to 0 when you unplugged coolant sensor connector like it should. 3. Bought a brand new coolant sensor/switch sending unit and that wasnt the problem. 4. Radiator gets hot like it should so I know its not the thermostat being shut closed. 5. Checked for air pockets and I burped the system added and topped off radiator even did it after it ran. Guys out of ideas anybody have this problem? I searched this forumns/google and youtube looks like I am the only character in the world with this problem. Prove me wrong here guys.
