The overall winning 4WD and the Best Large Wagon (Diesel) was the Land Rover Discovery 3 TDV6. The king of the castle is well, still king of the castle. Land Rover's brilliant Discovery 3 TDV6 has ruled over these awards since it was first released in late 2004. It actually arrived a little to late for the 2004 awards but it won 4WDOTY in that Land Rover Discover 3 TDV6 turbo actuator movement after removing turbo freeing up the actuator linkage boot and refitting the turbo Discovery 3 Cooling System Diagram. Hi guys, first post for me. I've changed my Coolant Overflow reservoir on my 2006 2.7 TDV6 D3 today, and notice somewhat of a kink on the bottom hose from the reservoir, has anyone else experience this? I tried to follow this lower hose but to no avail. The 2.7-liter Land Rover 276DT or Discovery 3 2.7 TDV6 engine was assembled from 2004 to 2010 and installed on Land Rover SUVs and a number of Jaguar models under the AJD index. On cars of the Peugeot-Citroen concern, this diesel power unit is known as 2.7 HDi. Joint development engines with Ford: 224DT, 276DT, 306DT, 368DT, 448DT. Specifications DQwg.
