Definitely seen better days lol<img src="http://i651.photobucket.com/albums/uu235/B33MER330/Maintenance%20Pics/IMG-20120731-00916.jpg" alt="" class="fr-fic fr-dii fr-draggable " style="" />She was already leaking for the past few weaks ... Having to top up water every few days<img src="http://i651.photobucket.com/albums/uu235/B33MER330/Maintenance%20Pics/IMG-20120731-00915.jpg" alt="" class="fr-fic fr-dii fr-draggable " style="" /><img src="http://i651.photobucket.com/albums/uu235/B33MER330/Maintenance%20Pics/IMG-20120731-00913.jpg" alt="" class="fr-fic fr-dii fr-draggable " style="" />10yr old water pump taken out<img src="http://i651.photobucket.com/albums/uu235/B33MER330/Maintenance%20Pics/IMG-20120731-00910.jpg" alt="" class="fr-fic fr-dii fr-draggable " style="" />looking rough but i reckon still functional. What is interesting that the impeller is metal and NOT plastics as what is claimed by others on e46fanatics.<img src="http://i651.photobucket.com/albums/uu235/B33MER330/Maintenance%20Pics/IMG-20120731-00911.jpg" alt="" class="fr-fic fr-dii fr-draggable " style="" />Radiator being installed ... <img src="http://i651.photobucket.com/albums/uu235/B33MER330/Maintenance%20Pics/IMG-20120731-00907.jpg" alt="" class="fr-fic fr-dii fr-draggable " style="" />Radiator bracket installed<img src="http://i651.photobucket.com/albums/uu235/B33MER330/Maintenance%20Pics/IMG-20120731-00925.jpg" alt="" class="fr-fic fr-dii fr-draggable " style="" />Water pump installed<img src="http://i651.photobucket.com/albums/uu235/B33MER330/Maintenance%20Pics/IMG-20120731-00947.jpg" alt="" class="fr-fic fr-dii fr-draggable " style="" />So since then the radiator, bracket, water pump and lower hose has already been installed. That's the EASY part lol the hard part is installing the hard pipe (no pun intended) that connects to the engine block ... Thus it requires the removal of the intake manifold<img src="http://i651.photobucket.com/albums/uu235/B33MER330/Maintenance%20Pics/IMG-20120731-00917.jpg" alt="" class="fr-fic fr-dii fr-draggable " style="" />Almost there ... Intake manifold was PITA to take out as there were a lot of wiring and cables were in the way. Patience is a must in this case lol<img src="http://i651.photobucket.com/albums/uu235/B33MER330/Maintenance%20Pics/IMG-20120731-00918.jpg" alt="" class="fr-fic fr-dii fr-draggable " style="" />Hard pipe installed ... It's quite tedious and does require a fair amount of time<img src="http://i651.photobucket.com/albums/uu235/B33MER330/Maintenance%20Pics/IMG-20120731-00948.jpg" alt="" class="fr-fic fr-dii fr-draggable " style="" /> Pouring the BMW coolant ... Only then start pouring the distilled water. Why distilled water is because it's purely water no mierals or contaminants that can form scales inside the radiator system. It enables better heat ransfer as a result.<img src="http://i651.photobucket.com/albums/uu235/B33MER330/Maintenance%20Pics/IMG-20120731-00953.jpg" alt="" class="fr-fic fr-dii fr-draggable " style="" />Pressure tested at 1 bar to check for leaks ... From what i gather M54 engine cooling system runs at 2 bar thus i'm not sure whether it's ideal to pressure test at half the working operating pressure level.<img src="http://i651.photobucket.com/albums/uu235/B33MER330/Maintenance%20Pics/IMG-20120731-00950.jpg" alt="" class="fr-fic fr-dii fr-draggable " style="" />Will update more with part III tomorrow ... Now need to get some :sleep:</blockquote>
