Heater core not such a bad job. Fiddly, yes. It means the entire dash has to come out but really it's mostly screws holding it all together. Worst bit is the engine hoses. I think they never suspected that a core would ever blow or that a hose would need to be replaced since they parked the engine RIGHT WHERE THE HOSES GO into the bulkhead. You are looking at removing the intake in order to access the hose; at least I find it easier that way.
Get the proper #2 PoziDriv bits, there are NO phillips head screws on a Rover.
