Replacing your 2005 or 2006 VW Timing Belt
It is important to replace your VW timing belt before your vehicle reaches 100,000 miles to prevent engine damage. Replacing your vehicle’s timing belt is relatively simple if you have the right equipment. To change the belt, you will need G12 coolant, a new VW timing belt, a torque wrench, a socket set, regular pliers, a car jack and jack stand, and a 10-millimeter triple-square bit. You will also need a crankshaft lock VW number T10100, camshaft pin VW number 3359, serpentine belt tensioner lock VW number T10060, and timing belt tensioner pin VW number T10115. You will need to buy these tools separately because the ones you need are made specifically for this job, but you can also rent them if necessary. Replacing your VW timing belt yourself can help save you from paying repair costs.
Prepare to Remove the Old Belt
Disconnect your vehicle’s negative battery cable. Loosen the lug nuts of the front passenger side wheel. Jack up the car and set it securely on the jack stand. Finish removing the lug nuts and remove the wheel. Pull off the plastic engine cover.
Remove the Pipes, Hoses, Clips, and Clamps
Remove the spring clips and the intake pipe. Separate the fuel and coolant hoses that cross over the piping. Next, remove the middle screw on the bracket.
Remove the Serpentine Belt
Use a 17-millimeter open wrench to turn the serpentine belt tensioner knob towards the front of the vehicle. Insert serpentine pin T10060 through the hole on the knob and into the tensioner housing to hold the tensioner in a loose position. Next, completely remove the serpentine belt tensioner.
Remove the Coolant Tank
Move the windshield washer fluid reservoir out of the way by removing the bolt holding it in place. Unplug the coolant level sensor located on the coolant reservoir. Next, remove the coolant tank and its upper and lower hoses. Drain the coolant from the tank. Unclip the wire loom and move it out of your way.
Remove the Wheel Well Liners
Remove the plastic splash pan and lower right wheel well liner located underneath your vehicle by removing the eight screws that hold them in place. Next, remove the front lower wheel well liner. Do not remove the center crankshaft sprocket bolt until you have something in place to support the engine.
Remove the Serpentine Belt Pulley and Timing Belt Covers
Remove the serpentine belt pulley. Next, remove the middle and lower timing belt covers underneath the vehicle. At the top of the car, remove the upper timing belt cover.
Insert and Adjust the Camshaft Lock
Make sure that the camshaft lock and the camshaft locking pin are aligned. When you insert the crankshaft lock, slide the tool’s interlocking teeth into the teeth of the crankshaft sprocket. Make sure that the peg on the lock fits into the hole on the metal piece behind the sprocket. Insert the locking pin all the way into the camshaft sprocket. Make sure that the pin is engaged in the hole.
Remove the Motor Mount
Pull up on the filter housing and set aside the fuel filter and fuel filter bracket. Support the engine from above or underneath the vehicle. Raise the engine up just enough to take its weight off the motor mount bolts. Remove the motor mount alignment plate, fender mounting bolts, and the mount bolts. The larger bolts should be loosened in order to help support the mount as you loosen the other bolts. Next, remove the bolts from the mount block and remove the mount block mount.
Remove the Timing Belt
Loosen the camshaft sprocket bolts and the timing belt tensioner bolt. Use a six-millimeter allen wrench to turn the tensioner counter-clockwise until you can fit tool T10115 into the hole, then turn it clockwise until it stops. Next, slip off the camshaft sprocket and tensioner at the same time and remove the timing belt.
Install the New Timing Belt
Carefully slide the new timing belt into place, being careful not to apply too much tension.
Reassemble the Vehicle’s Components
Follow the steps in reverse to return your vehicle’s components to their proper places. Reconnect the negative battery cable and test the vehicle to make sure that it runs properly.
Although it is a time consuming activity, learning to replace your VW timing belt will save you a great deal of money in the long run. Having the belt replaced by a mechanic can cost $750 or more in parts and labor, while the typical do-it-yourself job is roughly $250. It is relatively simple to accomplish as long as you have the correct tools and a few hours to spend working on your vehicle. By following these steps, you can keep your money in your wallet and your car on the road where they both belong.
