Mine was the same way in the winter. What I did when I removed my EGR cooler which really made a BIG difference with my truck in maintaining engine temperature in the winter plus a nice warm cab and actually reduced the amount of fan clutch engagement in the summer was to reroute the coolant flow that is coming out of the oil cooler thru a four port coolant valve, then to the heater core, then from the heater core back thru the four port coolant valve and from the four port coolant valve I have the coolant returning not thru the regular route which is across the firewall, to the degas bottle which is connected to the cold side of the front engine cover (which originally acts like a big 3/4" recycle loop), but to the hot side header of the front engine cover which originally was the heater core coolant supply. Of coarse you would need to block the original EGR cooler return port on the engine front cover. On my Ex I removed tapped and threaded in an aluminium plug but I have done the same coolant reroute on a number of buds trucks using just a stainless steel sheet metal disk at the donut. The logic behind my "Term3 coolant mod" as my buds have called it LOL, is that pumps have a specific volume of liquid that they can move at a given RPM so the original 3/4" coolant path from the hot side coolant header to the heater core and back to the water pump suction side is just a long bypass line that reduces the total flow going to the engine and oil cooler. More coolant volume being pumped to the engine block and oil cooler the better temperatures are going to be controlled by the thermostat which itself is an automatic bypass from the hot side header to the water pump suction. Of the guys that I helped do this coolant reroute with everyone of them were mad that I didn't think of it sooner once they had experienced the improvement. Next on my list of cold weather add-ons is a cab actuated rad "winter front".
