Default Bad water pump on a 91 Honda Accord that is leaking all the fluid. Do I need to lift the engine...

...out to repair? I took off the A/C Compressor, Alternator, belts, and splash guard from the top of the engine. I still can't reach the water pump which is run by the timing belt which needs changed also. This seems impossible as an at home fix. Any info would be appreciated!

I'd first of all recommend getting yourself a manual because lining up the marks when installing the timing belt is extremely important, and failing to do so will result in bent valves, severe engine damage etc..You don't have to lift engine although you do have to support it when removing the upper motor mount. You'll need sockets and wrenches 10mm,12mm,14mm,17mm. also while your in there be sure to check the tensioner bearing as well as the cam and crank seals.Usually the hardest thing about doing a t-belt job on a honda is removing the crankshaft bolt. You'll almost surely need a 1/2 inch drive impact gun or a special tool that is used on Honda's for this purpose. That and working in a limited amount of space is the only other issue. Take your time and make sure you follow the instructions when lining up the marks. Good luck and hope this helps..

No - it actually is not that hard to get to. The trick is that Hondas are like onions (or ogres) - they have layers. Remove all the parts that are in the way up top, including the power steering pump (be prepared to deal with the upper line dripping [I used a sandwich bag and shop towel] - leave the intake line attached) and the cruise control actuator. The driver's side front wheel has to come off, of course, as does the crankshaft pulley. If you have not done that yet, it is the most daunting part of the whole project. Renting an impact driver rated at least 500 ft-lb is a very good idea because that bolt is tighter than God's corset. See the first source for ideas and cautions.

I expected to have very little room to work but once everything was cleared out it was open enough to work easily. The Helm manual I used as a guide had me unfasten the engine mount on that side and put a floor jack under the oil pan but I couldn't see why - maybe on yours that will be important

you remove the mount that's in the way any way and you use a floor jack and a block of wood to jack the engine up from the oil pan.

1991 Honda Accord L4-2156cc 2.2L SOHC



* Inspect the water pump when replacing the timing belt.


* Turn the crankshaft so that the No. 1 cylinder is at TDC.

* Before removing timing belt, mark direction of rotation.

* Disconnect the negative battery terminal. (If the vehicle is equipped with an anti-theft radio, be sure to get the five digit code from the customer. After reconnecting power and turning the radio ON, the word "CODE" will be displayed. Enter the code at this time).


1. Remove the splash shield.

2. Disconnect the connector, then remove the cruise control actuator. NOTE:

o Do not disconnect the control cable.

o Take care not to bend the cable when removing the actuator. Always replace a kinked cable with a new one.

3. Remove the mounting bolt, nut and V-belt from the power steering pump, then remove the bolts and nuts. Loosen the adjusting bolt. Pull the pump away from the mounting bracket. NOTE:

o Plug the pipe and the pump port.

o Do not disconnect the hose.

4. Disconnect the alternator terminal and the connector, then remove the engine wire harness from the valve cover.

5. Loosen the alternator mounting bolt, nut and the adjusting bolt, then remove the alternator belt or air conditioning belt (cars equipped with air conditioning).

6. Remove the valve cover.

7. Remove the side engine mount bracket B (standard for some types).

8. Remove the upper cover.

9. Remove the side engine mount.

10. Remove the dipstick and the pipe.

11. Remove the adjusting nut.

12. Remove the special bolt and the crankshaft pulley. Remove the two rear bolts from the center beam to allow the engine to drop down and give clearance to remove the lower cover.

13. Remove the lower cover.

14. Push the timing balancer belt tensioner and the timing belt tensioner to remove tension on the belts, then tighten the adjusting nut.

15. Remove the timing balancer belt and the timing belt.


1. Install the timing belt in the reverse order of removal; adjust the valve clearances.

2. positioning the crankshaft and the camshaft pulley before installing the new timing belt. NOTE:

o Install the timing belt with the No.1 piston at TDC (Top Dead Center) on the compression stroke.

o When turning the crankshaft with a socket wrench, install the crankshaft pulley and the pulley bolt.

3. Align the groove on the front timing balancer belt driven pulley to the pointer on the oil pump body as shown.

4. Align the rear timing balancer belt driven pulley using a 6 x 100 mm bolt or an equivalent, mark a line at 74 mm. Align the rear timing balancer belt driven pulley by inserting the bolt through the maintenance hole. NOTE:

o The mark must be flush with the maintenance hole surface.

o When the special tool is not available, a 6.2 mm dia pin can be used as a substitute. Insert the pin as shown above.

5. Install the new timing balancer belt if necessary, then remove the adjusting nut.

6. Perform the tension adjustment of the timing belt and the timing balancer belt. See: Adjustments

7. After adjusting the belt tension, lock the timing belt adjuster arm with the 6 X 1.0 mm bolt used to tighten timing bolt lower cover.

8. Loosen the adjusting nut and check that the timing balancer belt adjuster moves freely.

9. Turn the crankshaft pulley about one turn:tighten the adjusting nut (adjustment is completed). NOTE:

o Do not apply tension on the tensioner when tightening the adjusting nut as the tensioner is spring loaded.


* Do not apply excessive tension to the timing balancer belt. It is designed to operate with smaller tension than those of other belts.

10. Tighten the adjusting nut and the 6 X 1.0 mm bolt from the timing belt adjuster arm.

11. Remove the crankshaft pulley.

12. Install the timing belt lower cover.

13. Install a new timing belt adjuster rubber seal without loosening the adjusting nut. NOTE:

o Never loosen the adjusting nut as this will be disturb the adjustment of the timing and balancer belt.

14. Install the timing belt upper cover.

15. Install the crankshaft pulley.

16. Coat the threads and seat face of the pulley bolt with engine oil, and tighten to the specified torque. Specified Torque: 220 N.m (159 ft. lbs.) NOTE:

o After reassembly, adjust the tension of the power steering belt and alternator belt or air conditioning belt.
