I fitted a new thermostat in the 2.8, I used a thermostat meant for the 3.1 Trooper rated at 85d Quinton Hazel 411, the engine heats up a lot faster, in fact the engine actually heats up now, where as before it would be lucky to touch the first white mark, it now sits nicely at just below the second white mark.
I am getting some actual heat out of the heaters now but IT still needs bleeding to bring it up a bit.
