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 Services

Cars are complex- make no mistake about it.

Electrics, computers, can-bus communication and all other necessities, there is a protocol which technicians have to follow- unfortunately the general public has no idea what is required so here is a attempt to demystify the whole process of servicing.

What is in a Car Service?

A service can be broken into three categories

  1. Parts
  2. Consumables
  3. Labour

Labour

  • basic general service for a car only

The vehicle is checked over for damage & scratches before test drive-test drive incorporates, listening for knocks, squeaks, rattles, driving braking shuddering. a full electronic check- load test battery @150-200 amps & monitor load performance, light check, interior lights power windows, perform full electronic computer scan-with report, check fuel trims.- under bonnet, check drive belts, check for any leaks (coolant or oil) check brake fluid & coolant concentrations, check radiator& cooling system, top up all levels.

Jack up car (HALF WAY) – check steering and suspension (shock absorbers, ball joints)  remove wheels check tyres-note condition, rotate tyres-check tyre pressures. Check brakes- include brake hoses , adjust brakes & hand brake.

Fully jack car up – drain oil, replace oil filter, check gear box & differential oil levels, inspect & report exhaust damage, engine & transmission mounts, check for lower suspension wear (IF ANY)-Check drive shafts(for torn boots or cv damage),tail shafts, grease if applicable. check for any structural damage or rust.

Lower car – fill with correct fresh oil- check air filter- replace if necessary, start vehicle-check for leaks-test drive.

Time is about 1- 1.5 hours price approx $120- $189.

Parts

If your car has a turbo (Diesel or Petrol) only full synthetic oil will be used.

Oil prices can range between $60- $120 –depending on make/model.

  • Oil filter approx $18-$38
  • Air filter approx $22.00- $80.00

Car Services

I have bared my soul when it comes to servicing prices my opposition will of course undercut me because that is business- A word of warning-beware of cheap service prices-gimmicks or gurus when you use a booking agency-you are sending money overseas(THEY TAKE 30% OF THE BOOKING FEE).., to finish  a small 4 cylinder car which is constantly serviced average price is around $250 – $300. Diesel 4wd can be around the $450 + diesel parts can be expensive-but i strongly recommend a diesel fuel filter with every service
