Guys I’m literally stumped. I’ve had my motor apart 5 times replaced everything on my cooling system. New fan clutch new auxiliary fan. Wired it to a toggle switch. New 180 degree thermostat. New cylinder head. New 2 row radiator. Installed a mechanical temperature guage to I can actually read the temperature. And now when I’m driving around town it stays cool 190 or below. When I get on the interstate and am pulling a hill it climbs to 230. My next option is taking the thermostat out and see how it reads but this thing should be running cold now.
