Re: water pump help

From what I've seen on my F20 (I would assume its similar):

Remove the timing belt covers
remove tensioner
2 bolts holding the water in (it looks like a wierd shaped metal plate with a gear on the outside)
Install and repeat in reverse

Now all this is with my motor out.

Re: water pump help

its an involved but not complicated process and I would suggest changing your timing belt front and rear balance shaft seals front main seal and cam seals and balencer belt while your changing your water pump. Its all right there and very good preventative maintenance and will add quit a bit of life to your engine. you may want to convert to the Manuel H23 tensioner for this as well this process is for a H23a1 its pretty much the same for the H22 someone correct me if i am wrong. this is the entire process with replacing the seals i have mentioned if you choose not to do this skip those steps(though i seriously recommend doing them now!!).
as for the process
(i forgot to add this. drain your oil if you replace the front main seal and the balence shaft seals)
1 remove neg battery cable

2.disconnect pcv and breather hose and ground wire from valve cover

3. remove power steering pump and lines and alternator and alternator wires now remove the brackets and move the PS lines and ALT wires behind the valve cover

4 remove valve cover

5.remove middle timing cover

6 jack up front of the car and remove the wheel(support the car with jackstands)
7 remove crossmember from under the engine

8 support engine with a jack and a small 2x4 from the oil pan

9 remove driver side engine mount

10 set cyl 1 @ TDC via cam markings and crank pully (cams have arrows on them make sure they align with the mark on the head right behind the cam gears they also have small notches that should face each other and the crank pully has a line that should line up with an arrow on the block. also set your flywheel to tdc via the timing mark on the flywheel with the TDC indecator notch. the window for this is right where your trans meets the engine to see this you must remove the little rubber plug right next to your engine stamp at TDC you will see a white line it will look similar to this -> when its lined up)

11 place a set of punches in the cams right behind the cam gears through the little holes in the cams and the cam retainers they will line up @ #1 TDC and lock them in place

12 remove crank pully....GET THE TOOL you WON'T be able to get it off with out it! i broke 4 strap wrenches trying with out the tool so just buckle down and buy it or borrow it from someone

12a your happy now that its off have a beer!

13 remove the maintence bolt from front of the block and insert a screw driver to lock the front balencer shaft in place

14 remove the maintenance bolt from the back of the block and do the same for the rear balencer

15 remove balencer shaft belt

16 remove timing belt

17 convert to Manuel tensioner now(look around for the tutorial)

17a have a beer

18 remove the front balance shaft gear by placing a screwdriver through the hole right behind the gear and loosening the bold that retains the gear take the gear off and do not lose the key!

19 remove the seal located where the shaft meets the block and replace it with a new OEM Honda one

20 place gear back on the balencer shaft reversal of removal tq to 27 ft lbs
21 remove "oil housing" via 3 bolts this is the rear balence shaft DO NOT TURN THE GEAR ONCE YOU TAKE THE HOUSING OFF BE VERY CAREFUL replace the seal with your new one and reinstall tq the three bolts to 20 ft lbs

22 remove timing and balence gear on the crankshaft DO NOT LOSE THE KEY
then remove the little gold washer thingy behind them take note of which direction these gears face as i put them on backward the first go around

23 be sure to use the apporate tool (I used a few of the wrong ones get the seal puller)
and pull the front main seal out and replace it (easy way to put it back on is a large socket and a rubber mallet

24 reinstall the washer thingy the key thetiming gear and balence gear on the crank shaft (do you rember which way they faced?)

25 remove cam gears DON'T LOSE THE KEY!

26 pull old cam seals out and replace with new ones use a little bit of permatex rtv black silicone sealant on the out side of these

27 put cam gears back on DON'T LOSE THE KEY! TQ bolts to 27 ft lbs

28 locate your water pump Loosen the bolts and remove the old seal and replace it

29 put water pump back on and tq to 108 in lbs

30 check your timing marks and make sure its all timed up correctly still

31 put Timing belt on reversal of removal (lol have fun)

30a now that your relieved that you got it back on go have another beer

31 put balencer belt back on reversal of removal

32 reinstall lower timing cover and crank pully and tension adjusting nut

33 now remove the balence shaft holding bolts you put in earlier and cam holding punches and reinstall the maintenance bolts that were originally there

33a have another beer

34 perform timing belt tension adjustment by loosening the adjusting nut 2/3 a turn then turn the crank 3/5 teeth via the crank bold and use the cam teeth to judge the 3-5 tooth turn then re tighten the adjusting bolt and check your tension you should not be able to twist it 1/4 of the way around

35 reinstall valve cover spark plugs alternator, PS pump all lines and wires brackets (all the crap you had to do just to get the timing covers off)

36 refill oil

37 reconnect battery

38 START YOUR ENGINE!!!!!!!!!!!!!!

I may be missing a few steps and this is for the h23 like stated before,but its pretty much all the same
if you feel uncomfortable or unsure about this take it to a trusted mechanic. I would also suggest finding the shop manuel online (available here on PZ you will have to search) it helped me greatly but all in all if your are going to attempt this TAKE YOUR TIME do not rush. and most of all ENJOY it dont get flusterd and just throw **** back together have fun with it I know I did.

Re: water pump help

As great as this help may all be, I would leave that job to the professionals. At least have someone supervise.

Re: water pump help

Might as well replace the belts, tensioners, and seals while your in there.
