I replaced all water hoses including heater and LPG today and it is a right royal PITA, 8 hours to do it all. I wasted most of the time doing the connections to the heater box. First of all those little clips that hold the hose are nigh on imposible to remove when the engine is in as they point up, if they were down then there is a bit more room to work with them from underneath. I ended up pulling two wires from a connector in the process which took several hours to trace and fix.
