What is Timing Belt?

Have you ever wondered what a Timing Belt is? 

Engine breathing & more important air flow is the heart & soul of good performance of a internal combustion engine.

How a Timing Belt works

I have selected 3 pictures to try to capture the job of a timing belt. The quintessential word here is “TIME”.

A brief run down:

In a nutshell the engine is a air pump with a piston moving up & down. The down speed of the piston causes a negative pressure (vacuum) and air enters the chamber via a intake valve (this can be through one or two valves) –  Induction Stroke.

The intake valve closes at a precise time, when the piston moves up it compresses the air & injected fuel (compression stroke) and the spark plug fires, causing a combustion process resulting in a flame front & high pressure. The combustion pressure forces the piston down at a precise time sending torque down the crankshaft turning linear force into rotating torque (power stroke).

As the pistons ends the downward travel, the exhaust valve opens at a precise time. The piston then moves back up pushing exhaust gases out the exhaust valve (exhaust stroke).

Why Do I have to Replace the Timing Belt

Timing is the issue & it has to be precise. To open & close valves at the precise time in relation to piston position, this requires a timing belt. These timing belts are due to be replaced approximately every ten years or at 60 000km – 100 000km. Some makes have different time intervals, so please refer to your repair manual for the exact times.

Stretched timing belts can throw the whole series of engine stroke events totally out of sync with the valve events, resulting in poor performance, poor fuel economy even possible engine failure!

Why so expensive to replace?

Replacing timing belts should also incorporate replacing the water pump. Some vehicles may require the engine to be removed from the car to replace the timing belt.

Many manufactures require special holding and locking tools to hold engine components in the exact position to install the belts. This can be very expensive just to get the right tools to do the job.

What is a Timing Belt?

Manny`s Mechanical repairs specialises in engine Tuning & excellent fuel economy, replacing timing belts, water pumps & timing chains. We ensure your vehicle is up to date & have the equipment to measure good fuel economy & power. Replacing timing belts is critical & should not be avoided costing can be around $1000.00 including labour(approx.), but that is better than losing your engine due to hubris or neglect.

I hope this has helped.

Car Noises and Vibrations Brisbane

Are you experiencing weird Car Noises and Vibrations Brisbane but not sure what might be causing it?

Read below some things you could be experiencing in your car and what you can do to fix it.

In the last few weeks I have had a number of customers who have had obvious problems with their cars- but have ignored vital signs because of their busy hectic lives, one case we just had a customer actually lost complete brake hydraulics in his front brakes- luckily he did not hurt himself or any one else.

The problem on hand is that if you choose to ignore these noises/signs then you actually become a customized to their frequency and the brain thinks this is normal-when in actual fact it’s a prelude of worse things to come.

Car – KNOCKS (Engine or suspension)

Knocking is the bad one- knocking/tapping-engine or suspension means metal on metal at a frequency it can mean poor or no lubrication, broken components, or component failure I have had cases where this has been ignored resulting in total engine seizure. (Worn ball joints, sway bar mounts, broken springs)-recommend not to drive and get towed to your work shop.

Car – GRINDING or GROANING

The two most common components that grind are brake component failure or a bearing roller failure-this could be wheel bearings, drive or tail- shaft bearing anything that has a bearing in it, Brake pads or brake linings can wear away to metal on metal surfaces, if you detect grinding I recommend getting the vehicle towed to your workshop

CAR – SQUEALING

Squeals can be manmade warning signs warning you that your brakes are worn low, squeals can be caused by dust particles between two surfaces or lack of lubrication in a bearing, dry ball joints, cracked or hard fan belts, squealing is a sign of worse things to come- so do not hope the noise will go away-just get it check out as soon as possible.

Car – THUMPING

Thumps are generally a suspension failure or a broken engine or gearbox mounts, thumping of a shock absorber is common when the internal shock valve or rod is damaged & has lost it hydraulic oil. Thumping may even be a out of round or scalloped tyre,-again if you detect a thump get it check out immediately.

Car – STEERING SHUDDER/ BRAKE PEDAL PULSATION

This one is not a noise but still very common, the main culprits of steering shudder is 1-out of round tyres or a tyre with a impact fracture, these tyres have been distorted and have lost their symmetrical shape. Another cause for steering shudder is distorted brake disc rotors-the distorted brake rotor pulses the brake pads back and forward as the brakes are applied. Also brake pulsating pedal can also be distorted rear brake rotors or a faulty wheel bearing.

Car Noises and Vibrations

There are numerous noises & vibrations which can happen in a car, there are many more for I have nominated the most common, remember if a noise or vibration begins do not endure with the issue hoping it will go away- nip it in the bud early for it will save you a lot of cash & make your car safer.

I hope this has helped – Manny 0411 496 621
