How long does it take to service a car and re-gas aircon system?

At least one hour, anything less means that the job is not being done correctly.


How much gas does my aircon system take?

It varies with car make and model. The refrigerant is metered by weight and a small car may take half a kilo, a luxury car with climate control may take one and a half kilos.


How often should my car aircon system be serviced?

Every 18 months to 2 years to ensure it operates at maximum efficiency. If you let the system run low on refrigerant the compressor has to work twice as hard and will therefore wear out in half the time.


How often should I run the aircon in my car?

All the time on hot or cold depending on the outside temperature. This will ensure that the rubber seals and gaskets in your system don't dry out and crack thereby causing leaks. Run your system for a few minutes every week at the very least. Contrary to popular belief it does not greatly reduce your mpg.


How to check oil level in Automatic gearbox?

In most cases oil level in Automatic gearbox is measured with the running engine, position of the gear stick "P" (parking). Oil in the box should be heated-up to 90°ะก. On the probe there should be some notches, sometimes only two, they correspond to normal level of oil. To warm oil to the necessary temperature you should pass about 20 km. Stop the car on the plain place. Wipe the probe, insert back and take out again. On probe there will be the oil level mark. On probe there can be bottom marks which correspond to level of cold oil. But it will be more correct to check oil in a warm condition. On some cars, for example Honda and Acura, oil is checked in a warm condition but at non-working engine. On some cars oil is checked at the gear stick position "N".


Why low or high oil level in Automatic gearbox is dangerous?

 Too low oil level is dangerous because the pump can take air together with oil. After that pressure can come down that can result in worsening of elements lubrication. Too high level can lead to oil foaming and as a result to gearbox breakage.


How often is it necessary to change oil in Automatic gearbox?

Term of oil change depends on Automatic gearbox type and usually, under normal operation conditions, it is recommended to change it after 70 thousand kilometers of run (or in 2 years) and after 25 thousand kilometers (or in 1 year) if operation conditions differ from normal ones (hot climate, cold climate, operation in the megalopolis, continuous operation of the car with full load, etc.). In some expensive models according to the maintenance guide change of oil is not provided. But despite anything,re gulay rl(once a week) check quality of oil in Automatic gearbox of your car. It is necessary to keep determined periods of change if in use there is no considerable change of quality of oil or you did not get into difficult traffic conditions (got stuck, towed another car for a long time etc.). In case of dimness of oil and/or burnt smell it is necessary to change it without waiting planned term of change. But not always change of burned oil can save situation. More often in these cases major repair of Automatic gearbox is required. During oil change in Automatic gearbox it is necessary to change also a lump gasket and the filter. In the some types of Automatic gearboxes filter replacement during change of oil is not provided, because the filter is not available without removal and reassembly of Automatic gearbox.


What is the overdrive? What of modes is more preferable in city conditions: drive or overdrive?

Overdrive in terminology of American car manufacturers means raising transmission. It is usually designated as "OD", either D or D in a circle. Raising transmission is recommended to use for measured, economical traffic on highways.


What is the kickdown?

If during movement you press against the stop a pedal of a butterfly valve control, in the gearbox there will be a switching on one or two transmissions down. This mode is recommended to use for obtaining higher values of acceleration that is useful, for example, during overtaking. Return raising switching in this case can occur only at engine’s taking of the maximum turns. If you loosen a pedal of butterfly valve control, the transmission will pass to a regular operating mode. It is necessary to understand that on the slippery road in the time of compulsory fall of transmission driving wheels can start to slip that can lead to drift skidding.


Do I really need a wheel alignment & suspension check?

Yes, a wheel alignment keeps your steering geometry in the correct position thus reducing tyre wear and overall saving you fuel in the process. Having a suspension check at the same time is recommended as this will highlight areas that could be of concern and giving you the opportunity to fix before costing a lot more. Remember, like an engine oil change a wheel alignment is a necessary service.


How often should I have this done?

 We recommend about once every 12 months.


What are signs that I might need a wheel alignment & suspension check?


Often things like your steering wheel is on an angle to drive straight, your vehicle veering unexpectedly, rattling noises while going over bumps and shaking of the steering wheel are certainly guides to the potential requirements of a wheel alignment. With these signs as well a suspension check would be recommended to ensure that these signs are not caused by something potentially more dangerous.


How often should I get my power steering rack and pump checked?
