Is it necessary to replace timing belt and water pump?
Replacing a timing belt and water pump does require a decent understanding of engines, so if you’re not that experienced working under the bonnet we’d advise you to leave it to the pros. But if you are and you enjoy doing your own repairs or restorations then it’s something you can do yourself, and save on some big repair bills in the process.
What’s the best way to replace a water pump?
Use a ratchet or wrench to break loose the water pump pulley retaining bolts (do not remove the bolts at this time). If the pulley starts to spin, you can try putting some extra tension on the belt tensioner to hold it in place. Remove the drive belt by rotating the automatic tensioner.
How do you change the timing belt on a mower?
Turn the camshaft sprockets fully clockwise. Fit the new timing belt, starting at the crankshaft (1) in a clockwise direction, then follow with idler (2), tensioner (3), camshaft sprockets (4), idler (5) and water pump (6). 6. Slacken the tensioner retaining nut and remove the locking pin.
How do you remove a water pump from a car?
Use a ratchet or wrench to remove the water pump mounting bolts. Remove the water pump from the vehicle. If the water pump doesn’t come off easily, give it a couple of taps with a dead blow hammer to break it free. Some water pumps are driven off the engine’s drive belt, while others are driven off the timing belt or timing chain.
When to replace timing belt and water pump?
Tensioner mechanism removal. While not necessary, it is highly recommended that the water pump be replaced whenever doing timing belt service, as this is the only time the water pump is accessible. Remove the idler pulley and tensioner pulley. They are each held in place with (1) bolt.

Where do you take the timing belt out of a car?
Put the engine in gear (to prevent it spinning when you’re removing the timing belt) and engage the handbrake. The fan belt and power steering belt sit beside the cover which houses the timing belt and water pump, so you’ll need to remove them first.
How long does it take to change timing belt?
Changing a timing belt and water pump can take anywhere from 1-3 hours depending on your skill level, so make sure you have the time and space to complete the job. Do the following before you start: Jack up the front of the car so you can access the undercarriage beneath the engine.
Where are the timing marks on a timing belt?
(2a) Find the timing marks on the flywheel and cam, and set them both to TDC. (2b) The flywheel pulley TDC mark is accessible through a hole in the bellhousing. (2c) The camshaft TDC is easy to find — especially if you add white paint as we did.
Do you need to remove motor mount for timing belt?
Study the procedure before digging in, either in a service manual or on the Web. On most transverse four-cylinder engines, you’ll have to remove the passenger-side motor mount in order to gain access to the timing belt. This means the entire powertrain needs to be supported in that area while you’re working.
Is the timing belt connected to the water pump?
The timing belt may also drive the water pump . More than half of all engines that have timing belts (some use timing chains, which are not the same) also use the belt to drive the water pump. This is mostly due to the location of the belt to the pump. Because of this, anytime you replace one, you should replace the other.
When should the timing belt/water pump be replaced?
- Rough engine noise when idling
- Heavy vibration when idling
- Misfiring of the engine
- Excess smoke from the exhaust
- visible by an engine warning light or increase in temperature
What is the normal life of a timing belt?
The expected lifespan of your timing belt is specific to your car and engine configuration, usually between 60,000 and 100,000 miles. (You can check your owner’s manual or look online for your car’s service schedule.)
When to replace timing belt?
Every car manufacturer recommends replacing the timing belt after a given time, and it is imperative to take this advice. The time or distance between timing belt replacement depends on the specific make and model of the vehicle, but on average it should be changed every 100,000 miles.
What’s involved in timing belt replacement job?
In most cases the technician must remove the serpentine drive belts to the alternator, A/C compressor and power steering pump. Once the timing belt is removed, the bulk of the labor is already done for a water pump, camshaft, crankshaft seal replacement.
Is the timing belt the same as the drive belt?
Note, the timing belt isn’t the same as the serpentine (‘drive’) belt, Autoblog explains. True, both are connected to the crankshaft. However, the former is located inside the engine, albeit by the outer wall. The latter is found externally, and drives many of the car’s accessories, like the alternator, power steering pump, and A/C pump.
How much does a broken timing belt cost?
If the timing belt breaks on an interference engine while it’s running, the result is often catastrophic engine damage costing around $2,500 to $4,000. Other engines are designed with more space at the top of piston travel. Those engines can survive a broken or out-of-time timing belt. They’re referred to as “free-wheeling.”
Water pumps usually fail before the engine reaches 200,000 miles, so shops usually recommend replacing the water pump at the same time as the timing belt. The reasoning is that the bulk of the labor has been performed to remove the front portion of the engine and the timing belt.
What do you need to know about timing belts?
The timing belt system includes idler pulleys and a belt tensioner. These components should be replaced along with the belt. On some cars, the timing belt drives the engine’s water pump.
What should I do if I need to replace my water pump?
Remove timing belt tensioner and idler pulleys. Remove timing belt. If replacing the water pump, do so at this time, and of course drain the cooling system first. If the engine cooling system thermostat is only accessible with water pump replacement, the thermostat should be replaced as well.
When to replace timing belt in Acura RDX?
These engine designs are referred to as interference engines. If your car has an interference engine, replacing the timing belt according to the maintenance schedule will minimize the chance that a belt failure will cause engine damage. How do mechanics replace the timing belt?
