I guess this is obvious, but you'll need to be absolutely sure that the cooling system is in good condition - rad, rad hoses, thermostat, coolant, rad cap, viscous fan coupling, no spilts in the pipe from near the rad cap to the expansion tank, no splits in the pipe inside the exp. tank etc. Hope this helps. Oh and make sure all the glow plugs get fitted back in the correct way otherwise you'll just keep blowing the fuse!

If you don't have the coolant pipes to the throttle body, there are rubber blanking caps on the fittings. (one on the head, and one below it on the block) These have been known to perish and leak water.



Apart from that, its just normally cooling systems checks, ie, waterpump, leaks around rad or hoses, etc that caused it to lose water and overheat in the first place. Often its the headgasket which failed, which you'll replace anyway doing the head.
