We have a 72 fj40 with F engine - just rebuilt.
New 180 degree thermostat
New 2F water pump with fan clutch and fan from a 60
Fan shroud is installed
13 lb radiator cap with release lever
We burped the radiator
New 4 core radiator
New oem head gasket, correctly installed.
After market electric water temp guage
After we start the engine, it takes less than 5 minutes to heat all the way up to 280.
I am totally out of ideas - is there anyone that can either shed some light on what the problem might be, or that can spend a little time helping us figure it out?
TIA, Max and Max's dad.
