Trying to loosen the crank shaft polly to change water pump

Yes,there is a special wrench that fits the water pump. You have to loosen bolts on pump and put wrench on pump and turn pump to get belt on. Then tighten pump till marks line up on tensioner,then tighten the pump back down. Be sure to roll the engine around twice and recheck timing marks on crank and cams.

Timing belt set-up for a 2000 Seat Inca 1.9 SDi

1. Align the crankshaft timing marks on the flywheel / gearbox


2. Remove the valve cover
3. Lock the camshaft


4. Fit the injection pump locking pin



5. Loosen the camshaft gearwheel bolt, 180 degrees. Use a wrench to counter-hold
6. Loosen the camshaft gearwheel while holding it in place



7. Fit the timing belt in the sequence as shown in the below figure: a - b - c - d - e - f - g



8. Fit the timing belt and camshaft gearwheel together
9. Turn the tensioner clockwise to align both marks



10. Tighten the large bolt on the tensioner to a torque of 20 Nm
11. Check for correct fit
12. Lock the camshaft. Tighten the camshaft gearwheel bolts: 45 Nm. Use a wrench to counter-hold
13. Remove helping tools
14. Turn the engine two rotations by hand
15. Repeat the procedure if required
16. Fit the vacuum pump
17. Refit the crankshaft pulley. Tighten torque: 20 Nm + 20 degrees
18. Fit the timing belt cover
19. Refit the valve cover
20. Fit the ancillary drive belt
21. Refit the inlet air manifold hoses
22. Check the injection timing

Torque settings:
Camshaft gearwheel: 45 Nm
Tensioner pulley: 20 Nm
Crankshaft pulley: 20 Nm + 20 degrees

Take the shroud & fan off , loosen alternator and air conditioner remove belts, remove belt pulley off face of water pump, drain radiator, remove water pump, remove belt off harmonic balancer, then pull harmonic balancer off of crank shaft, remove bolts from timing cover, and that will get you to the timing chain plate take the bolts out and remove it.

1.u need to jack the car up so u can take the passenger tire off. align the crank timing mark to top dead center with the front timing belt cover. 2. u need to loosen the crank bolt with am impact wrench, or secure the flywheel and lossen the crank bolt .3. u need a 10mm short 1/4 inch socket/or wrench inch to loosen the (4) water pump nuts. 4. i now recommend u loosen the alternator, u do not need to remove it. 5. if u have air-conditioning..i suggest u leave it on. remove the belt 6. powersteering can be loosened as well, 7. once u remove the crank pulley..u can take the 10 mm blots out of the timing belt/water pump covers.u will also need to support the engine(under the oli pan is ok) and remove the upper passenger side motor mount. 8. u will now see the timing belt. u need to remove it by loosening the tension pulley (14 mmm bolt) .u should make sure the crank is tdc. but u just need to make sure that when u re-install the new timing belt(whichu better do when u do a water pump)...,make sure the exhaust and intake cam shaft pulleys are aligned.(exhaust pulley is front side of car, intake is rear.)(e-for exhaust,i -for intake....they're aligned at center of each other (center of engine)now i must take a pee,brb in a minute. remove timing belt now 9. remove (5) 12 mm bolts from water pump. clean surface. 10. re-install in complete reverse order.i do recommend u use a black rtv gasket sealer on ur water pump gasket.(screw manufacturers statements on this use). tart with taking your two belts off, remove motor mount, remove power steering pump, crank pulley,next remove timing belt covers along with tensioners. Remove valve cover. timing belt tensioner, now you have access to the water pump. remember your timing marks before you remove. When installing timing belt hold camshaffts with vise grips to align. installation opposite of removal.

I aligned the crank shaft,,water pump pulley. and the cam shaft marks up and recheck the origninal marks I made to save time....one of the cam shafts had slipped enough to cause it to be "off time" and the computer could not correct for it...realignment of the marks and making sure nouthing changes was the solution..

you should check the water pump polly u can rotate it back an forth if it easly goes change it , or you can hear a nois sound comming from the water pump

could be the a/c compressor. The compressor went up on my jeep and it made horrible sounds. Hold a kindlin stick or large screwdriver to the compressor with engine running and put your ear to the other end. You will be able to tell if this is the problem. Dont get to close to the belt

These engines are identified as an interference engine and on no account must the crank shaft and cam shaft be moved with the timing belt removed. You no not need to remove the water pump. You need to remove the water pump pulley only (not the water pump). I trust this helps.

use a impact gun with a few extensions is the easiest solution. I can assure you that trying to loosen it by hand will not work. Be careful, sometimes that bolt on various vehicles has reverse threads.

No. There is no trick.
