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 does the timing belt drive the water pump?
Using the timing belt to drive the water pump lends itself to compactness at the front end of the engine. Some special purpose vehicles have remote or supplementary water pumps. Having snapped alternator and water pump belts in the past, I feel the most likely reason is engine safety.
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.
How does the timing of an injection pump work?
When you adjust the timing, you can alter when the engine injects the fuel, therefore changing when combustion occurs. An injection pump is often driven indirectly from the crankshaft by chains, gears or a timing belt that also moves the camshaft.

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.
How is the water pump on an Ecotec 4 cylinder driven?
The water pump for the Ecotec four-cylinder engine is driven by the chain that turns the engine balance shaft. This will increase access to the pump and thermostat housing on the back of the engine.
Should I replace the water pump at the same time as the timing belt?
If that is the case, then it is advisable to replace the water pump & auxiliary drive belt at the same time as the timing belt while the mechanic has access to all the parts. Once the timing belt is removed, it is only a matter of loosening a few more bolts and screws to change the water pump as well.
What happens if the timing belt fails on a Porsche Cayman?
And if the timing belt fails, whether due to simple age, or the failure of a tension pulley or bearing, the water pump will likely fail along with it. Also, as with the Porsche Cayman’s RMS, the water pump isn’t easy to get at. In fact, ClickMechanic and NAPA explain, you can’t get at the water pump without first exposing the timing belt.
