How to change the timing chain on a water pump?
13. Remove the three water pump bolts. Make a maximum gap between the water pump gear and timing chain by turning the crankshaft pulley counterclockwise until the timing chain loosens on the water pump sprocket. 14.
Is the timing belt and water pump the same thing?
The latter is found externally, and drives many of the car’s accessories, like the alternator, power steering pump, and A/C pump. But, as NAPA explains, the timing belt sometimes pulls double-duty. Not only does it keep the crankshaft and camshaft (s) synced, it sometimes also drives the water pump. Why replace the water pump and timing belt?
What do you need to know about timing chain replacement?
Also verify that your model is equipped with a timing chain and not a timing belt. These two parts perform the same task, but replacing them can be quite different. This procedure is only for replacing a timing chain. Clean the engine with the proper degreaser thoroughly before beginning.
How does a chain drive water pump work?
Keep the slack guide pressed and hold the plunger in by pushing the stopper pin deeper through the lever and into the tensioner body hole. e. Make a gap between the water pump gear and timing chain by turning the crankshaft pulley approximately 20° counter clockwise (Figure 2). 12. Remove the chain tensioner.
Where is the timing chain on a water pump?
The water pump is attached to an idler sprocket of the left bank of the timing chain. To replace the water pump, both chains need to be removed. This pump has been known to go 200,000 miles or more.
Why do you need to change your timing belt and water pump?
This might be preceded by a ticking noise coming from the engine bay. In addition, the gasket separating the timing cover and engine block may fail over time, causing oil to leak out. It is technically possible to replace your car’s timing belt and water pump yourself.
Where is the timing chain on a boxer engine?
Since the 2000 model year, just about every flat-six boxer engine has timing chains. The water pump is attached to an idler sprocket of the left bank of the timing chain. To replace the water pump, both chains need to be removed. This pump has been known to go 200,000 miles or more.
What causes a chain driven water pump to fail?
Another reason why chain-driven water pumps fail is a worn or defective tensioner and guides. Most engines use oil pressure to actuate a tensioner that puts pressure on a guide. If the tensioner fails (typically due to a lack of oil changes), the chain will move around due to centrifugal force acting on the chain.
