picked up a 2004 d2 with a new motor. previous owner was a lady who overheated the motor and cracked the block. new engine, heads, radiator and a bunch of other stuff done by land rover. all documented. love the truck.

 

Welcome. Three things to be aware of:

1. The front drive shaft from the factory has no grease fittings on the double end. They dry out, snap, and try their best to bang a big hole in the side of the transmission. Replace shaft, or have the one you have rebuilt, and then grease every oil change. A drive line shop may charge $125 ish to rebuild it, and we have a DIY article in out tech area.

This happens very frequently, don't put it off.

2. Despite all your work on the motor, the factory heat gauge will point at 50% from about 130 - 240F. You don't know if overheating has started, unless you attach a scanner that shows live data to the OBDII port. There is a 180F warm weather thermostat (only buy a real Land Rover one, like from Rovers North or others - not a Motorad brand). This thermostat will cut your engine temps across the board, and make those repairs last even longer.

3. Change oil early and often, like 5000 miles tops. Shell Rotella 15W40 is a good general purpose oil with lots of extra cleaning compounds built in.

Shop and owners manual is called the RAVE by Land Rover, free download links below.
