From the workshop

Posted on July 19th, 2011 by Rob Marshall

Names can be ambiguous. ‘Fun Run’ is one particular term that I think falls against everything that the Trade Descriptions Act stands for and, during the rare times that I spend away from my beloved workshop, it is one such activity that I strive to avoid at all costs. ‘Antifreeze’ is another name that is also misleading. While the designation hints at its most obvious property, many owners are fooled into thinking that, provided enough antifreeze resides within their engine’s cooling system, it is protected for evermore.

They are wrong. Antifreeze has several other qualities, one of which prevents corrosion from developing inside the motor’s various passages, through which the coolant is pumped to dissipate heat. If corrosion starts, it can constrict the channels, in a similar way to cholesterol causing eventual arterial blockages in humans, and the risk of the engine either overheating or suffering from cylinder head gasket failure increases dramatically.

Sadly, antifreeze’s anti-corrosion properties diminish with time and it is wise to request that your garage flushes and replenishes the cooling system at a next service, or prior to the autumn setting in, should you be unsure of when it was last done. Most cars need this doing between two to five years.

The owner of a 1997 Vauxhall Corsa thought that she was hearing things, when her exhaust started blowing again, barely a month after she paid to have it replaced.

With the car raised on a ramp, it was clear that her previous garage had fitted new front and centre exhaust sections but not the very corroded rear silencer, which had rusted through.

When the owner was quizzed, she admitted that she instructed her garage to keep the repair costs as low as possible, which explains why a gamble was taken on the old part.

From the garageFortunately, the rearmost exhaust silencer was not expensive to source, for such a popular car, and the old part was removed and replaced without any problems being encountered. Ironically, it would have been more economical for the owner to have had the entire exhaust replaced initially, rather than paying for two separate repairs.

From the garageFrom potholes to speed calming measures, leaking shock absorbers, worn ball joints and even broken springs are common maladies that the average garage has to deal with.

Even so, even technicians can be surprised. The owner of a 2002 Renault Mégane was complaining of a dull thud coming from the car’s rear floor, after the rear wheel was driven into a pothole. A careful test-drive revealed that the underside sounded as though it was being clouted with a cricket bat, every time the car negotiated a bump.

With the Renault raised by a ramp, the rear wheels were left to dangle. Immediately, it was obvious that the driver’s side rear shock absorber had snapped away from its mount, which meant that the damping medium was no longer secured to the car body.

Shock absorbers must always be replaced in pairs and so, once two new rear dampers were supplied and fitted, the customer could enjoy her Mégane once more, although she has vowed to be more aware of potholes.
