Hey dudes and dudettes,

I hope that everyone had a great weekend! As for me, I spent the better portion of it getting my hands dirty whilst changing the water pump on my 2000 Prelude. On the plus side, I not only didn't lose any major limbs during the entire laborious process but I also saved mucho dinero by undertaking the job myself. For those of you who enjoy tinkering on your Prelude AND saving cash, then this D.I.Y article is for you

Important: The original radio contains a coded anti-theft circuit. Obtain the security code number before disconnecting the battery cables.

1. Disconnect the negative battery cable.

2. Drain the cooling system into a suitable container.

3. Remove the accessory drive belts, the valve cover, and the upper timing belt cover.

4. Set the timing at TDC/compression for the No. 1 piston.

5. Remove the crankshaft pulley and lower timing belt cover.

6. Remove the timing belt. Replace the timing belt if it is contaminated with oil or coolant or shows any signs of wear and damage.

7. If equipped with a Crankshaft Speed Fluctuation (CKF) sensor at the crankshaft sprocket, unbolt the sensor bracket and move the sensor out of the way. Cover the sensor with a shop towel to keep coolant off of it.

8. Unbolt the water pump and remove it from the engine block.

9. Clean the water pump and O-ring mating surfaces before installation.

10. Install the water pump with a new O-ring. Coat only the bolt threads with liquid gasket and tighten them to 108 inch lbs. (12 Nm).

11. Install the timing belt. Be sure it is fitted and adjusted properly.

12. If equipped, install the CKF sensor and tighten the bracket bolts to 108 inch lbs. (12 Nm).

13. Install the lower belt cover and crankshaft pulley.

14. Install the upper timing belt cover, the valve cover, and the accessory drive belts.

15. Be sure the cooling system drain plug is closed. Refill and bleed the cooling system.

16. Connect the negative battery cable and enter the radio security code.

17. Start the engine, allow it to reach normal operating temperature, and check for coolant leaks.

That's it, folks! Make sure that you check the coolant level for the next few days

Never known anyone to replaced JUST the pump, the only time it should fail is if it is a cheap part or wasn't changed when the timing belt was changed. Which is why it's a huge waste of time to replace everything even the oil seals behind the timing covers when you have that all apart.

yeah it's probably for when the water pump breaks or when it wasn't replaced when the timing belt was changed. Cool DIY tho. +1
