How often do the fuel injectors need to be serviced?
 |
Fuel injectors have very fine passages in the discharge nozzle and rely on the fuel filter to pass only clean fuel. However if the fuel contains liquid contaminates of similar viscosity to petrol then the filter will not hold this element back, in fact it is this situation that leads to the injector passage restriction by a varnish like substance. It is very important to ensure only clean fuel goes into the tank and that the tank is cleaned thoroughly in the event of a load of bad petrol or diesel. |
| Liquid fuel additive 'injector treatment' is sometimes a stop gap measure to carry on but if the injectors are to perform at their best then they should be removed and professionally serviced. | |
| If you suspect a decline in performance then have your vehicle professionally diagnosed, this is a relatively inexpensive process and begins with an analysis of the exhaust gas where the individual gas components can be measured and from this a precise picture of anything amiss is drawn together. |
How do you know if you have poor quality fuel?
|
Bad fuel is fuel from the bottom of a service station tank, which may contain residual sediment and/or water accumulated over time. You will know if this is the case because your car will run poorly, or stop, within a few kilometres of filling up. |
How often does brake fluid need to be changed?
|
Brake fluid should be changed every 2 years because it is hydroscopic - that means it absorbs moisture from the atmosphere and therefore has the potential to become unstable. |
| To explain: Most brake fluids have a boiling point of 270 degrees C in their pure form that is before water dilution. Water boils at 100 degrees C and its presence in the brake fluid will lower the temperature where vapour will begin to form. | |
| The presence of vapour means that some of the brake pedal movement is taken up in compressing the vapour instead of applying the brakes. If enough vapour is present the brake pedal will go right to the floor. | |
| The problem may never show itself in cars that are driven only in the city where braking loads are light and braking temperatures moderate. However vapour point and subsequent loss of brakes will most likely occur on the highway where vehicle loads and speeds are higher and this is more critical in summer months. Running out of brakes will definitely spoil your day. |
Why does my brake pedal jump when I brake hard, or in
wet
weather?
|
Motor vehicles fitted with an antilock braking system will generate brake pedal feedback under heavy braking because of the way the ABS operates. For the system to prevent brake lock up it releases braking pressure on the wheel or wheels that are about to lock (skid). Because the brake pedal is the origin of the pressure what you feel is the pulses of pressure relief. |
How can I jump start a vehicle and not damage electronic
components and car computers?
|
Using only good quality heavy duty jumper leads, connect the red Positive (+) jumper clamp to the dead battery, and connect the other positive clamp to the positive terminal of the battery of the starting vehicle. Connect the negative clamp of the cable to the negative terminal of the battery in the starting vehicle. Connect the other negative clamp to the vehicle's engine block or other metal surface of the car but well away from the battery in case of a spark. Make certain all cables are clear of fan blades, belts and other moving parts of both engines and that everyone is standing away from the vehicles. Start the car of the battery providing the jump start, then try to start the car with the dead battery. If the car starts, allow the engine to idle for approximately 5 minutes, before removing the cables in the reverse order that you connected them. |
Are car air conditioning leaks preventable?
|
Car air conditioning systems need to be serviced from time to time and the older the vehicle the greater the possibility of leaks developing as a result of hoses and seals breaking down from the extreme under bonnet temperatures. It is everybody's environmental responsibility to contain refrigeration gasses in their sealed environments and regular servicing of your car's air conditioner by our trained technicians will help enormously. |
