first up --is the timing belt going back in the same direction you took it off
if you don't know then get a new belt as an old belt running in the wrong direction to which it was running will fail very quickly and if that happens there is valve bending problems
next the timing marks face each other exactly( 9 and 3 oclock)
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.
you should did your home work before removed old water pump most vw engines water pump is part of the timing belt assembly so when time to replace around 80k miles you should order complete timing belt kit which includes water pump with it. so after you finish up if you didnt try to hard to run engine you may or may not damage any piece from your valve train!!even with all proper parts you have on your hand you still need high cost speciality tools to complete timing belt replacement on that engine recommendetion is tow your vehicle to mechanic shop and let them do it for you it will save you time and money! good luck!
There are marks that you have to line up. The folowing pictures are for DEMOSTRATION PURPOSE ONLY- YOUR MARKS MIGHT BE DIFFERENT. Once all the marks are lined up then you can install the belt, set the tension and rotate the engine two full turns to make sure all the marks line up.
Hello, Here are the steps for removing and reinstalling your water pump.
Disconnect the positive battery cable.
Put a drain pan under the radiator and drain the coolant. Drain the coolant out via the drain plug on the radiator.
When drained close the drain plug.
Put another drain pan under the timing belt cover.
Now you need to remove the timing belt cover.
Use a ratchet and remove all the bolts to the time belt cover.
Remove timing belt cover.
When you get the cover off remove the timing belt.
***NOTE*** due to the time, labor and potential cost of replacing the water pump and the fact that the timing belt is right there it is recommend to put a new timing belt on during the installation process.
Remove the bolts that secure the coolant inlet pipe with a ratchet.
Remove the pipe and gasket.
Remove the belt and idler pulley attached to the water pump. Don't get and coolant or grease on it.
Now you need to remove the mounting bolts from the water pump with a ratchet.
Remove the pump.
Inspect the seating of the gasket real well.
Remove all the crud off it with a lint free rag, I repeat lint free rag.
Now to install the new water pump
Install the new water pump with the new gaskets provided. Never reuse the old gaskets.
Install mounting bolts and torque them at 14-18 foot pounds.
There is a bolt that will connect the alternator bracket to the water pump that needs to be torqued at 23-38 foot-pounds.
Reinstall the idler pulleys and tighten down with your ratchet.
Replace the gasket for the coolant intake pipe with the new gasket.
Now torque the remaining bolts to 14-18 foot pounds.
Slide the [hopefully new] timing belt back.
Reattach the timing covers.
Tighten them bolts with your ratchet.
Use a mix of 50% water and 50% antifreeze and fill up the radiator and overfill.
Squeeze the radiator hoses a few times to get the air out of the hoses.
Hook your battery back up.
Start the car and let it heat up to full running temperature, with the heat on and check for leaks.
What is needed Tools: 6mm and 8mm allen wrench socket, 5mm allen wrench.
8mm, 13mm, 19mm socket and ratchet. 10mm combination wrench. Long
ratchet extensions (at least one 6in, more are helpful). 5inch Wheel
puller (for main shaft pulley). (Some models may need a special spanner
tool to adjust the timing belt tensioner) Parts: 2 gal of anti-freeze
mixed with distilled water. All three V-belts. (Alt, A/C, P/S) $32.95
New water pump top. $91.91 New gasket for WP. $9.13 New timing belt.
Remove battery cable (either power (+) or ground (-)) remove
alternator remove A/C remove power steering pump .Remove water pump pulleys remove
main shaft pulleys remove timing belt covers remove A/C mounting
(don't turn any of the wheels its connected to) replace timing belt
water pump face put on new gasket and new part.
Leave pulleys off.
replace bottom timing belt cover, replace crank shaft pulley, replace steering
pump, replace A/C, put small belt on A/C (hang loose) put large belt
around A/C, Main and water pump pulley. put middle size belt on Main water
pump and power steering pump reattach bolts for the steering pump
pulleys put alternator back on adjust all belts. connect battery
areas: Main pulley: There are 4 6mm hex head bolts. These must be
removed. The main 19mm hex head can be used to turn the engine it the timing belt
slips and you have to readjust the timing.
Putting on new
belts: This can be a real pain if you get VW belts. The adjustments won't
give enough to put the belts over the edge so the easy way is to remove
the pulley on the water pump. Then its real easy.
If you turn the wheels that the timing belt goes on you will
have to reset the timing. Mark the timing points with something
like whiteout so its easy to see. The timing mark on the toothed
gears are small dots. The timing mark for the crankshaft is a small cut
on the outer pulley. When its aligned with the intermediate wheel timing
mark (there is an arrow on the cover as a hint) should intersect as viewed
from the right wheel well. The camshaft timing mark should line up
with the top of the engine near the front.
Power steering pump: It is
held on with lots of bolts. One is in a channel that is hard to see but
can be found with a 6" extension. If you look at the pump you will see
three bolts that go into the housing. This should give you an idea where
the forth is.
The best way to do this yourself is to get a HAYNES or other auto manual. This is a complicated procedure and if not performed EXACTLY, timing can thrown off, not to mention the fact that engine damage can occur.
Usually it is just a matter of aligning the timing marks on each cam (double overhead cams) AS WELL AS the crankshaft (bottom pulley) all at the exact marks to make sure the timing is not disturbed. These manuals would be worth their weight in gold to get the exact procedure done correctly. The manuals are only about 20-30 bucks, and contain a boatload of other useful info also.
1-Tear down engine sufficiently to access removing the timing belt cover.
2-Remove timing belt cover.
3-Turn engine over slowly and manually (by hand) until you have reached the ALIGNED points described by the MANUAL.
4-Remove the timing belt TENSION ADJUSTER, then the timing belt.(It is CRITICAL that the timing is not disturbed at this point, until the timing belt is installed.
*Do not reinstall the old timing belt, use a NEW one.*
5-You now have access to the water pump/mounting bolts.
6-Replace the water pump.
7-Reinsure the timing marks proper positions as you install the NEW timing belt, taking into account the slack that the tension adjuster you also will install will remove.
8-Recheck your timing mark alignments by turning the engine by hand back and foth some.
9-Reinstall the timing belt cover.
10-Reinstall all the components that you had to tear down to gain access for this job.
If you double checked your timing calculations, and your water pump replacement, everything should be good to go.
It's a little time consuming, you will need a harmonic balacer puller/reinstaller tool, and air tools will knock it out much quicker. Your back might be aching a lil by the time this job is complete.
To change the water pump on the 1.8 or 2.0 4cyl is a complex project. The water pump is driven by the timing belt which means you have to remove the timing belt cover. Once youve done that you will need to release the tension on the timing belt make sure you have aligned the timing marks on both the camshaft and crankshaft sprockets before loosing the timing belt and be sure you do not move them while the timing belt is off and be sure they do not move while putting the belt back on. The tensioner will have to be locked down either before or after taking it out if after you will need to compress the tensioner and stick a small drill bit through the holes that way when you install it back all you have to do is pull the bit out and the tensioner does the rest. Once the belt is loose then you can remove the water pump and install the new one.
