[TR] tr3 cooling

[Tony Drews]

Is the shroud between the radiator and the grill of the car 
intact?  That part makes a huge difference in the efficiency (while 
the car is moving, anyway).

If the problem is getting hot while sitting still, then working on 
the fan is an excellent idea - but I don't have input on which fan 
option is better.
