With Electronic Fuel Injection Systems (EFI); the fuel pump is often located within the fuel tank so that the tank can be pressurised to pump fuel to the engine rather than require a vacuum pump at the engine that could pull in air and cause erratic engine running

It is possible for current ECU technology to monitor oil pressure and detect a sudden drop or no oil pressure and switch off the fuel pump to prevent the engine seizing, hence it may not always be a problem with the Mazda fuel pump

Fitting the fuel pump within the Mazda fuel tank below the fuel level allows the liquid fuel to actually keep the pump cool and reduces the risk of the fuel igniting accidentally

Mazda fuel injection engines require fuel to be pumped under pressure from the fuel tank to the engine fuel injection system

Fuel delivery into the Mazda fuel injectors is normally controlled by an electronic control unit (ECU) with inbuilt safety features to switch off the fuel pump in the event of an accident or fault

If you've been involved in an accident and your Mazda won't start then an inertia switch may have tripped the power supply to the fuel pump and need resetting

Metallic particles in the fuel filter could be caused by a faulty or worn out fuel pump and may eventually block the fuel injectors and require a very expensive repair

Longton Brake Servicing - New Disc Brakes & Pads

Mazda brakes can last for thousand of miles depending on use and regular service

The brake pedal controls the Master Cylinder (a fluid filled hydraulic piston) that transfers stopping power to the brakes

Braking increases hydraulic brake fluid pressure

The enforced contact between the brake pads and brake drum or brake disc increases friction to slow down or stop the vehicle

The hydraulic brake fluid is a non-compressible liquid so braking pressure is transferred via the brake pipes to the wheels and operates a slave cylinder piston that forces the brake pads against a brake drum or brake disc

Modern Mazda braking systems use hydraulic links to transfer stopping power

Mazda Hydraulic Disc Brake and Drum Brake Systems

Drum Brakes, if fitted, are usually found on Mazda rear wheels

In hydraulic braking systems, braking pressure operates a slave cylinder

Drum Brakes are an older system than Mazda disc brakes and use two half moon shaped brake shoes that move outwards during use to apply a frictional stopping force against the inside of a brake drum

Hydraulic braking pressure forces a brake calliper to press the brake pads against the disc to apply the necessary stopping force

Mazda disc brakes have a pair of high friction brake pads mounted either side of a brake disc

Mazda Brake Servicing - Mazda Brake Maintenance & Parts Replacement

The brake pads on your Mazda should wear first

Mazda brake discs will wear and need replacing eventually and should be inspected for pitting

If the Mazda brake discs warp then they should be replaced immediately

Mazda Brakes will safely function correctly without the need for replacement for many thousands of miles

if the Mazda brakes overheat and are allowed to cool with pressure still applied for m the brake pads/shoes then it is possible for the disc to warp.

Mazda Steering - Steering System Inspection

Common symptoms of Mazda steering alignment problems include:-
Vehicle Drift - Your Mazda tends to pull left or right when travelling in a straight line
Modern Power steering and Drive by Wire Systems do not have the same mechanical linkages between the steering column and drive wheels making it difficult to 'feel' how the steering is performing.

The tyre tread is rapidly removed from the inner or outer tyre edge of your front tyres

One of the first signs of a potential problem with your Mazda steering system is uneven tyre wear

The tyres will need to be replaced much sooner than necessary until the steering rack is adjusted to bring your wheels into correct alignment

Mazda steering inspections:-

Steering Condition

Mazda Tyre wear and wheel alignment

Wheel Bearings for wear - play or noise

Correct wheel balance, including spare

Power Steering Reservoir Levels and Top Up

Tyre Condition - inc Spare

Steering Rack Gaiter condition

Correct wheel nut torque to manufacturer's recommendations

Steering Linkages for wear and corrosion

Correct Tyre Pressure - inc Spare

Mazda Brake Servicing: Brake Discs, Pads & Hydraulics

Brakes can last for thousand of miles depending on use and regular service.

The hydraulic brake fluid is a non-compressible liquid so braking pressure is transferred via the brake pipes to the wheels and operates a slave cylinder piston that forces the brake pads against a brake drum or brake disc.

Braking increases hydraulic brake fluid pressure.

Modern braking systems use hydraulic links to transfer stopping power.

The brake pedal is attached the Master Cylinder; a fluid filled hydraulic piston.

The enforced contact between the brake pads and brake drum or brake disc increases friction to slow down or stop the vehicle.

Mazda Replacement Timing Belt or Cambelt Longton

If the timing belt snaps it will most probably cause serious engine damage. The camshaft stops turning with some of the valves left in the open position. In a Free Running Engine there is enough clearance between a fully open valve and the piston head to avoid serious damage. In an Interference Engine there is no clearance and the engine relies upon accurate timing to keep the valves and piston head separated. With a broken timing belt; the inertia helps the crankshaft to rotate freely forcing the pistons to strike the open valves resulting in damaged valves, pistons, and possibly even damage to the cylinder head

Generally Mazda belts should be replaced every 60,000 miles or less. So, if you have just bought a secondhand Mazda that has 40,000 to 80,000 miles then it is important to know if the timing belt has been replaced or needs replacing. Check the Mazda Owner's manual for your model for the recommended changing frequency

High compression diesel engines are normally interference engines

Often it is prudent to replace a combination of items associated with the timing system. Most of the needed Mazda parts can be obtained as timing kits containing the appropriate timing components; such as: Mazda timing belt
timing belt tensioners
timing belt tensioner idler roller
front lower crank shaft seal
water pump gasket

Since Mazda Timing Belts are hidden inside the engine they tend to be forgotten when purchasing a used Mazda

The toothed belt connecting the engine crankshaft to the camshaft is known as the Cambelt or Timing belt

Timing belts must be replaced at a specified manufacturer's interval. The timing belt should also be inspected regularly and replaced immediately if there is any evidence of cracking or fraying cuts or excessive wear

The Timing Belt synchronizes the camshaft to the crankshaft position ensuring the valves open and close at the correct time in relation to the piston. Some vehicles use a cam chain in place of the belt or a timing gear system instead

Mazda Clutch Replacement Longton

The pressure plate comprises heavy-duty release springs, a metal pressure ring acting as a high friction surface to interact with the clutch disc, a thrust ring (or thrust fingers) for the release bearing, and release levers

Engaging the clutch forces the clutch against the flywheel transmitting power from the crankshaft to the transmission shaft

The centre of the clutch disc has a spline pattern that matches splines on the power input shaft of the transmission system

Mazda Clutch failure often occurs when one or more of the high friction surface materials wears out on the disc. Even when the pressure plate is engaged and a clamping force is applied, there is no longer sufficient friction to transmit power without the clutch slipping. Normally the Mazda clutch disc and pressure plate are replaced. Replacing the Mazda Clutch is a major operation and it is sometimes advisable to replace a number of items, often supplied as a Mazda Clutch kit:-
Mazda clutch disc
pressure plate
release bearing
pilot bearing - bushing (when required)
internal Mazda clutch slave cylinder

When the clutch is dis-engaged the clamping force is removed so the clutch disc spins with the flywheel and no power is transmitted

Disengaging the clutch acts on heavy-duty release springs to isolate the pressure plate so that the disc is no longer pressed against the flywheel

The Mazda clutch disc is, not surprisingly, a disc with each side covered in a high friction material. It is designed to engage with the high-friction surfaces of the pressure plate and flywheel. It is also designed to transmit power to theMazda transmission system

Mazda Fuel Injectors - Fuel Injection

Mazda Re-Mapping Longton
The Mazda ECU can be replaced with a programmable ECU or re-mapped to electronically alter the engine performance characteristics

Mazda Engine Mapping
The Mazda ECU controlling engine performance is pre-programmed with software containing embedded data on engine performance for different combinations of engine speed and acceleration

EFI - Electronic Fuel Injection
The Mazda fuel injection system is controlled by a mini-computer or Electronic Control Unit (ECU) that assimilates data from a series of temperature sensors and oxygen or lambda sensors providing feedback to help optimise fuel efficiency and power under a variety of conditions

Mazda Fuel Injection
Fuel injection systems mix fuel with just the right amount of air for optimal combustion & energy release in an internal combustion engine

LPG Petrol or Diesel Metering
Fuel Injection systems have replaced carburetors for the accurate mixing and delivering of petrol, lpg or diesel fuel in modern Mazda vehicles

Mazda Engine Oil Change

Oil & Filter Change
A new Mazda oil filter and oil change shouldn't need a specialist Mazda engineer and is minimal compared to the cost of an Engine Rebuild; with regular maintenance and routine servicing working out cheaper than disaster recover when your Mazda engine fails

Synthetic Oil Change - Longton
Modern synthetic oils can last longer than old petroleum based multigrades because they are more inert with a laboratory designed molecular structure and fewer natural catalytic impurities that increase oil breakdown compared to the cheaper engine oils

Anti Oxidants
Preventing internal engine oxidation in your Mazda motor is the job of sacrificial anti-oxidants present in the lubricating oil; Anti oxidants are sacrificed to protect your engine and will eventually be depleted making it necessary to change your oil regularly

Oil Change Masterclass
Keep a small amount of the engine oil used in your next oil change in a sealed container; then when you check your oil level with the dipstick you can compare the lubricity or lubricating properties of the oil against your fresh oil:- If the oil on the dipstick seems thin compared to your reference oil sample; it may be time to get an oil change to keep your Mazda running smoothly

Moisture Scavengers - Detergents - Acidity Regulators
Moisture scavengers, detergents and acidity regulators prevent all kinds of contaminants degrading and abrading the internal moving surfaces of your Mazda engine minimising the effects that water, particles, and fuel combustion residus can have on Mazda performance
Once they have absorbed the maximum amount of water and other contaminants; the risk of corrosion and failure in your in your Mazda engine increases

Oil Change Frequency
The mechanics rule of thumb with traditional multigrade engine oils used to be "change the oil every 3000 miles" but many vehicle manufacturers indicate 5000 to 7000 miles. Initially, follow the Mazda recommended oil change guidelines to ensure you validate your warranty.

Oil Composition
Engine Lubricating Oil is composed of hundreds of chemicals; some can interact chemically, polymerise, oxidise and break down with the extreme conditions of temperature & shear forces pulling the oil molecules apart in your Mazda engine thus, changing the lubrication properties.

Mazda Replacement Exhausts Longton

The Mazda exhaust system allows poisonous gases from the fuel combustionto vent into the atmoshpere away from the driver and cabin

Corroded exhaust pipes allow fumes and noise to escape; increasing the risk of poisonous carbon monoxide entering the cabin and significantly increasing noise making detection an easy task

Explosions from the instantaneous ignition of the compressed fuel and air igniting in the combustion chamber creat a lot of noise that needs to be silenced in the urban environment

The exhaust pipework helps muffle and deaden the noise from the fuel combustion process
