Vacuum Hoses

A faulty or leaking vacuum hose can lead to poor engine performance and ultimately cause more serious problems when not addressed. This is due to the fact that the modern fuel injection systems incorporated by modern motor cars require vacuum to establish the condition of the engine. Based on this information, the engine computer will determine how to calibrate and pressurise the fuel injectors.

In the event of a leak, the computer will not be able to get obtain accurate information and the engine will run on a petrol-rich condition which, over time, may lead to engine damage.

How Do You Know If Your Air Hose Is Leaking?

The way your car idles is a good indicator of the condition of the vacuum in the air hose. It will idle unevenly and the engine speed will fluctuate. When you try to accelerate, the engine will be slow to respond. You may notice poor fuel economy as your vehicle uses additional petrol for each cycle.


How To Find The Leak In Your Air Hose

Park the car on a flat surface and open the bonnet.

Leave the engine running and listen to locate the leak. You may hear a hissing sound, the sound that created when air is pulled through the faulty air hose.

If you try to move the leaking hose, you may notice a change in the sound it makes and your engine may even respond differently. If you run your finger over the leak, you may feel suction on your fingers.

Fuel hoses


Also known as a fuel line, a fuel hose is what moves the petrol between points in a vehicle. DOE fuel hoses are made from reinforced rubber, to ensure durability against splitting and cracking.


How do you know when your fuel hose needs replacing?

Cracks and breaks in the rubber are symptoms that the time has come for you to replace your fuel hose. If you notice a petrol leak on the ground after you’ve parked your car, it could be due to a perished hose.

Heater hoses


An integral component of the car’s cooling system, a heater hose transports coolant from part of the engine to another.

The most common sign of a heater hose leak is leaking coolant. You may also experience steam rising from your engine, a sharp increase in the temperate of the engine, or the car overheating suddenly.


How To Find The Leak In Your Heater Hose


Allow the car to cool down for at least 30 minutes after driving it. Open the bonnet to release some of the heat but make sure it has cooled down completely before you touch anything.

Find the heater hose and inspect it for signs of cracking, breakage, or dripping fluid.

Once identified, remove the faulty hose. If the wear is located close to the end of the hose, you can also cut the damaged part away.

Connect the end of the new heater hose to the clamp and fitting.

If you need help, ask your trusted mechanic.
