Find parts for your car
One of the most important components, whose function is to provide protection to the interior of a car’s engine compartment, is the cowl top panel ventilator. This is a panel that can be found at the bottom of the vehicle’s windscreen in close proximity to where the windscreen wipers are connected to the car. Whilst it is important that the cowl top panel prevents unwanted items of debris, such as mud, leaves and sticks from penetrating the engine compartment it is also important that it permits adequate ventilation.
The driverside cowl top ventilator louvre provides this much needed ventilation on the driver’s side of the vehicle. It is able to achieve this because the cowl top louvre on the driverside has a set of ventilation grilles cut into it. These are sufficiently small to prevent objects from getting inside the panel but large enough to allow air to get in and out.
If the cowl top ventilator louvre on the driverside or the passengerside becomes damaged and begins to allow debris to infiltrate the engine compartment it should be replaced right away in order to prevent the consequential damage that might be caused to the engine and other mechanical components within the engine compartment.
