Black flow to Radiator reservoir tank??

[chestatee]

94 6.5td diesel- there's not a lot and the temp gauge has increased some and it stays consistent. Running open thermostat and radiator was boiled 2 years ago.
Any thoughts or suggestions would be appreciated, Thanks

is there bubbles when it's runnin' at idle?

I haven't noticed any.

you might have air in the system.....put a T-Stat in and it will run better and get better fuel mileage.......diesels like heat....

Good suggestion. If there are bubbles in the tank then what is your thought?
Thanks

Bubbles would indicate a bad head gasket or cracked block. Usually in that case your oil would be milky.
