Squeaky steering

Squeaky steering 

Whenever a customer complains of noisy steering, the first thing we check is the power steering fluid.

Very often the first sign of fluid loss is an increase in noise as the fluid mixes with air, causing the pump to become noisy.

 Not all vehicle owners notice a drip of oil on the road, and if the rack is failing, the oil can still be contained within the rack boots.

This 2001 Ford Focus was in exceptional condition for its age and when the owner noticed the strange noise on turning he bought it along to us.

Checking the fluid level in the steering reservoir, we found it to be almost empty. Putting the Focus up on the ramp for a look underneath, we soon discovered the tell-tale signs of fluid loss and traced the damp trail back to a leaking pressure switch.

Ordering up a new switch, we discovered it came complete with the small section of pipe to which it was connected. At £40, the price was not excessive, and once up and fitted, the leak was cured. After topping up the reservoir, the noise was silenced. 

How to fix Whining engine

 Whining engine 

This picture is of the BMW 330i.

 This BMW 330i had developed a whining noise that only stopped when the auxiliary drive belt was removed.

As the belt drives the water pump, along with the alternator, power steering and air condition, as well as running around a couple of idler pulleys, there were quite a few possibilities of where the noise was coming from.

 Stripping off the cooling fan and cooling, along with the air filter housing, gave plenty of room to access the problem area.

With the auxiliary belt off, all of the individual pulleys could be spun. Although the water pump was showing slight signs of wear, the bearing appeared to be smooth.

The tension pulley was showing a roughness when spun. The alternator felt smooth when the pulley was spun by hand, but this is not always a guarantee that all is OK as things can change when it’s under load.

In the end, it was discovered that it was indeed the alternator causing the problem when under load. We also took the opportunity to fit a new water pump and tension pulley, both of which needed replacing anyway.

How to change a Fuel Filter of a car

Easiest fuel filter change ever

how to change a fuel filter of a car

 When the service parts arrived for this 2009 Audi A6 2.0 TDI, we noted that the fuel filter was a long, slim unit that is normally fitted along the fuel line under the vehicle, either near to the fuel tank or fuel pump.

This is not the case with the A6 diesel. The fuel pump is fitted underneath, near to the engine bay and protected by a plastic undertray, running in line with the front-to-rear fuel lines.

The filter is located under the bonnet and is one of the easiest diesel fuel filters to change – the connecting pipes have spring clips and the filter itself is held in place by the securing bracket using one 10mm nut.

With the ignition off, the filter is easily swapped over and, once in place, it requires no bleeding.

Turning on the ignition for a couple of seconds before attempting to start the engine is sufficient to charge the system with fuel. 

How to fix Stiff Steering of Car

Stiff steering 

 The power steering pump was whining every time this 2002 MINI Cooper S was driven around a bend, leading the owner to believe the electric steering pump was the problem.

When we took a look, however, it was apparent that the steering wheel felt lumpy and uneven. So before diving in and replacing the pump, we decided to ensure the steering mechanism was not putting undue pressure on the pump. Removing the rubber boot at the base of the steering column to expose the U/J connecting the column to the rack, we noticed how rusty it appeared.

 Disconnecting the U/J and lifting it away from the rack, we realised it had seized solid in one direction. The joint from BMW comes complete with the lower column for around £140, but this can only be fitted with the upper column at a further £400 plus fitting charges. Instead, we decided to try to free off the old U/J.
