How much it cost to replace a timing chain?
Typical costs: Hiring a mechanic to replace a timing chain typically costs $300-$1,000, depending on the make and model of the vehicle, its age and whether the work is performed at a dealership or an independent shop. Purchased separately, a timing chain typically costs $50-$250 or more.
How do you change the timing chain on a water pump?
Remove the belt. Once tension is released, the belt should slide off of the other pulleys easily. Remove the heater hoses from the water pump. If your model has heater hoses attached to the water pump, loosen the hose clamps with a screwdriver and slide them back onto the hose. Wiggle the hose and pull it off of the water pump.
What should I do if my timing chain goes bad?
This is a sensitive procedure that can cause serious engine damage if not done correctly, so you’ll want to leave it to a professional mechanic. If the water pump is driven off the timing chain, it’s a good idea to replace the pump at the same time, as a preventative measure.
Can a timing chain be replaced on a pushrod car?
In old-style pushrod engines, replacing the timing chain is a fairly easy task. No such luck if you have a modern front-wheel drive car with a transversely-mounted engine, as the space in the engine compartment could be very tight.
How does the timing belt work on a Toyota?
Timing belts typically snake around idler pulleys and a special tensioner, and on most timing belt engines, the timing belt will drive the water pump, and on some, the belt even spins the oil pump (see 2.2L Toyota engines).
When to reinstall the timing chain on a water pump?
If you exceed 20º with the tensioner slacked, the chain could jump. When the new pump is installed, you will need to reinstall the tensioner. Turn the crankshaft pulley approximately 20° counterclockwise so that the timing chain on the timing chain tensioner side is loose, and then install the tensioner.

Can a broken timing belt cause a water pump to break?
With an interface engine, the valve opens further into the combustion chamber, so a broken timing belt can cause big problems. A malfunctioning water pump can cause the belt to break, which can cause the piston to strike and damage the valve, which results in major engine repair and major dollar signs.
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.
