|Cheap wash can prove expensive
Question : THE engine of my six-month-old
Toyota Vios needs washing due to
an oil spill.
I'm thinking of going to a roadside car wash as it's cheaper. But
friends say that should water enter
certain engine components during
washing, the engine can malfunction and eventually require expensive repairs.
USING electronic components to
reduce exhaust pollution and maintenance cost is commonplace these
days. In fact, cars now hardly use traditional mechanical metering of fuel
using carburetors and the ignition distributor to control ignition. Instead,
fuel and ignition are controlled by a single module known as the Electronic
Control Unit (ECU).
Electronic components are very sensitive to static electricity and
moisture due the extremely small currents that flow through their circuitry. Any minor disruption is likely to
result in a malfunction. So no moisture should enter any of the electronic
circuitry under any circumstances.
Washing the engine with a pressure washer would certainly result in
moisture entering the electronic components, unless they are protected in
the first place.
I suggest you take your vehicle to
your local authorised Toyota workshop for cleaning, even though it may
