Long story...I bought a 2000 D2 for $200 the owner says it overheats i said it might need head gaskets ...he says he did them I asked if he replaced the bolts and sent the heads out to be planed he said that is a wast of money the bolts looked fine and the heads don't need planing....so i brought it home took it apart sent the heads out got new bolts put it back together with a new water pump, fan clutch,radiator, and 180 thermostat..i looked at the block and all the liners looked OK I put it all together and it still overheats it is geting a lot of pressure in the cooling system.....so i was on craigs list and there was a listing for a land rover engine the person bought it from a junk yard out of a rear ended rover it sat on an engine stand in his garage for a few years then he noticed his disco had a rear rotted frame and junked it and i bought the motor it came with 2 intakes an alternator, and $169 worth of new parts from Atlantic Brittish,,I was in a hurry to load it and didn't really check it out when i got it back to my shop i noticed 2 things 1 was a different thermostat and 2 it has no power steering pump...i did some research and the thermostat is out of a P38 now i need to figure out if this is a 4.0 or 4.6 and did they make P38s without power steering????
