How do you replace the water pump on a 1986 Honda Prelude 2.0L si?

Answer 1

The answer is compicated. You need to go to a car parts store, and get a repair manual (Haynes Manual is very good) for your car. They cost about $16.00. Or, go to a Public Library and check-out the manual. Consider changing the water pump, the camshaft's seal and crankshaft's front oil seal since you have to go remove the timing belt to replace the WP and seals anyway. Here are the BASICS (see manual) for an '87 SI:Disconnect negative side of battery. Drain coolant. Jack up front. Remove left wheel. Jack up engine (slightly) and unbolt engine mount. Remove spark plugs and accessory belts. Set #1 cylinder to Top Dead Center(TDC). Remove cruise control. Remove upper timing belt cover. Remove alternator and bracket. Check for clearance around A/C compressor(may have to remove). Remove crankshaft pulley. Remove water pump pulley (8&12 valve only). Remove lower timing belt cover. (After timing belt installed, the install is reverse of this paragraph). The water pump and seals (mentioned above) would now be changed. The timing belt is then carefully installed without moving the cam or crankshaft. Several small details in the book need to be followed for installing the timing belt. Well, that's an overview. The manual is a must -- you can't afford to mess this up because it will PERMANENTLY DAMAGE engine parts if you don't do EVERYTHING JUST RIGHT! Obviously, the main cost of having a shop change the belt is in the labor. So if you do it yourself, do it right and plan on at least two days.
