Step-by-Step Instructions
Follow these steps to replace the timing belt on your Audi A4 2.0 TDI:
Step 1: Remove the Timing Belt Cover
The timing belt cover is located at the front of the engine. Use a socket wrench to remove the bolts that secure the cover in place. Once the bolts are removed, gently pull the cover away from the engine.
Step 2: Remove the Serpentine Belt
The serpentine belt is located on the front of the engine and drives the power steering pump, alternator, and air conditioning compressor. Use a socket wrench to release the tension on the belt tensioner and remove the serpentine belt.
Step 3: Remove the Water Pump
The water pump is located on the front of the engine and is driven by the timing belt. Remove the bolts that secure the water pump in place and gently pull the pump away from the engine. Be careful not to damage the gasket on the back of the pump.
Step 4: Remove the Timing Belt Tensioner and Idler Pulley
The timing belt tensioner is located on the side of the engine and maintains tension on the timing belt. Use a socket wrench to remove the bolts that secure the tensioner in place and remove the tensioner. The idler pulley is located on the front of the engine and helps guide the timing belt. Remove the bolt that secures the idler pulley in place and remove the pulley.
Step 5: Lock the Crankshaft and Camshaft in Place
You will need to lock the crankshaft and camshaft in place to prevent them from moving while you replace the timing belt. Use the camshaft locking tool to lock the camshaft in place and the crankshaft locking tool to lock the crankshaft in place.
Step 6: Remove the Timing Belt
Remove the timing belt from around the camshaft and crankshaft. Be sure to note the direction of the timing belt so that you can install the new timing belt in the correct orientation.
Step 7: Install the New Timing Belt
Install the new timing belt around the camshaft and crankshaft in the correct orientation. Be sure to follow the manufacturer's instructions on how to properly tension the timing belt.
Step 8: Install the New Water Pump, Tensioner, and Idler Pulley
Install the new water pump, tensioner, and idler pulley in the reverse order of how you removed them. Be sure to torque the bolts to the correct specifications.
Step 9: Install the Serpentine Belt
Install the new serpentine belt around the pulleys on the front of the engine. Use a socket wrench to release the tensioner and apply tension to the belt.
Step 10: Reinstall the Timing Belt Cover
Reinstall the timing belt cover and torque the bolts to the correct specifications.
