Hi all, Five years ago when I bought my Zed from 1996, after a very close inspection, I found that all parts on the car were from factory. I started the search on different forums in order to find out what is falling and when, so I can avoid unnecessary costs when travelling abroad (especially that ruin the holiday could create more damages from my wife's side, as we all know!) I found out (including from the BMW dealer) that water pump life time it's about 90-100 000km and the thermostat plastic hooks usually get broken, for ageing and the water hardly reach the right temp when chili outside....Last autumn I noticed some times the engine's temp droping so I imagined the Thermostat it's faulty: broken plastic bracket. As the water pump breakage brings colateral damages (fan, cooling radiator, hoses, and so on ) I decided to change them both, but I was scared by the obstinacy that some mates described, when trying to extract the water pump from the engine: hammer, WD40, swearing, etc). Because my Zed has 171 000 km I decided to not take any risk and start the procedure! Everything went nice (no swearing) and smooth like in a Pelican or TIS description and the surprise was that despite of all estimations the water pump was in a great condition (I still have tears in my eyes ! like loosing a good friend) and the famous plastic brackets of the thermostat were in position! The engine it's looking great, no corrosion...... When opening the packing box of the Bugatti water pump , purchased from Ebay, surprise: With more tears into my eyes, this time swearing included too, I ordered a Ruville water pump: So the myths regarding water pump life time max 100 000 km (mine 171 000 km and still great shape!) and breakage of the plastic brackets of the thermostat aren't always true! Myth Busted! Maybe the engine was never overheated and always with quality antifreeze or it's just the God of mechanics smiling sometimes...... But the thermostat was faulty; I have seen how the new one works after running the engine. Conclusion: I love the M44!
