if its the jag engine it needs a pump to push the hot water round the heater matrix as it wont get hot if its not working, that's why i don't drive my jag in winter, pump is imposable to reach without dismantling half the engine
as far as i know its the correct one but knackered, Carmichael are long gone, there is a plate attached to the wing saying it has non standard pistons in it, which is part of the problem in that it needs a replacement piston
a lot do, they rust in all the normal range rover places, always leaking from the pump and the form accelerates the rust, the early ones have non standard size doors makes repairing them a bitch
no all airfield fire trucks have to be all wheel drive, so tacr2's were all produced as 6x6, my one is actually a riv but looks much the same as a tacr2, they are often converted to 6x4 in civi street to save wear on the centre tyres
