DIY: 如何换汽车水泵

Replace the water pump of 2000 Toyota 4runner 4-cyl.

我喜欢摆弄车。一般维护都是自己动手。比如Change Oil, Air Filter,  Fuel Filter,  ECU,  Transmission Fluid, Coolant,  Brake Pads, Spark Plugs, O2 Sensor,  PCV,  P/S belt,  A/C belt, Alternator, Install Step Bar, Bull Bar & Rear Spoiler, Waxing, Tire Rotation.  最大的工程是2006年换掉2000 4runner 水泵。水泵没坏，因为就要跑长途，就把该换的都换了。当时第一次换，心里没底，因此每一步都拍照记录。现整理一下与朋友们分享。我的参考资料是Haynes Repair Manual.  注意：换水泵时要顺手把各传送带换了。传送带很便宜，贵的是LABOR。一般换水泵时还要顺便把Timing Belt换掉，但这辆车用Timing Chain，无须更换。感觉修车最大的困难是卸螺钉：螺钉有时锈住(要用WD40)；工具无法拧到螺钉(买合适工具，拆卸其它零件使空间扩大)， 螺帽磨平；螺钉花十字磨平(严重时要动用钻头把螺钉取出)。。。

0. Project Overview

1. Remove skid plate

2. Remove battery (to give you more space)

3. Drain the cooling system. Coolant 要送到指定Waste Management Center，否则违法。Toyota Coolant是红色的，不是绿的。

4. Remove the fan shroud and fan assembly

5. Remove power steering belt, alternator/water pump belt, air conditioning belt

6. Remove the water pump pulley. Disconnect radiator hoses

7. Remove the water pump bolts and water pump (compare the new one to the old one)

8. Installation is the reverse of removal

9. Refill the cooling system and check for leaks.
