Common Reasons Why Cars Stall and How to Prevent Them
Experiencing a car stall can be frustrating and inconvenient, especially when it happens unexpectedly. For those new to manual transmission vehicles, stalling is a common occurrence, often leaving drivers feeling overwhelmed and uncertain. However, drivers can gain confidence on the road with a deeper understanding of the common reasons for stalling and practical tips to avoid it.
Let’s explore the most common causes of stalling and how to avoid them.
Mechanics of Car Stalling
Before finding out the reasons behind stalling, it is essential to understand the mechanics of how it happens. In a manual transmission car, stalling occurs when the engine’s revolutions per minute (RPM) fluctuate or drop too low, causing it to shut off abruptly. This can happen when the clutch is engaged too quickly or when the vehicle is inappropriately geared for the driving conditions.
Common Reasons for Car Stalling
Here is a breakdown of the common causes of car stalling:
Forgetting the Clutch
This is a common mistake, especially when stopping. You might forget to press the clutch pedal before coming to a complete stop. Whether it’s due to forgetfulness or lack of timing, failing to disengage the clutch can result in the engine struggling to maintain its momentum, leading to a stall.
Tip to Avoid This
One of the fixes of car stalling is to develop a reflexive habit of pressing the clutch before applying the brake. The more you drive, the more automatic pressing the clutch becomes. Try anticipating stops and pressing the clutch a couple of car lengths beforehand.
Wrong Gear Selection
Attempting to move off in too high a gear is another common cause of stalling a car. This often happens when drivers mistakenly engage a higher gear, such as 3rd instead of 1st, leading to insufficient power for starting the vehicle.
Tip to Avoid This
Use the ‘palming method’ to shift gears. This involves using your hand position to feel your way through the gears, ensuring you select the right one. Practice gear changes without looking at the gear lever to develop confidence in your gear-shifting abilities.
Releasing the Clutch Too Quickly
This is a common issue for new drivers, especially when starting in a hurry. Releasing the clutch too quickly disrupts the engine’s smooth operation. This can result from a lack of clutch control or a desire to accelerate rapidly, especially in busy traffic situations.
Tip to Avoid This
Understand how the clutch works. Practice finding the ‘bite point’ – the point where the engine starts to engage with the wheels. Slowly release the clutch after reaching this point.
Shifting to an Incorrectly High Gear
Accidentally shifting to a higher gear immediately after moving off is one of the reasons for stalling a car, as the engine struggles to cope with the increased load. This often occurs when drivers are not accustomed to the gearbox layout or fail to gauge the appropriate gear for the driving conditions.
Tip to Avoid This
Practice gear changes in a manual car without starting the engine. Get familiar with the gear positions and transitions. Use the palming method for smooth gear selection.
Insufficient Acceleration
This is particularly true for petrol cars. Not giving enough fuel by pressing the accelerator, when starting can starve the engine of power, leading to a stall.
Tip to Avoid This
Remember the ABC – Accelerator, Brake, Clutch. Give the engine a little fuel before releasing the clutch. You might need slightly more fuel for uphill starts.
Hill Starts
Driving uphill requires more power from the engine compared to flat surfaces. If you don’t provide enough fuel, the car might stall due to the additional workload.
Tip to Avoid This
Increase throttle input slightly before moving off on an incline to provide extra power. Adjust throttle input based on the steepness of the hill to ensure a smooth start without stalling.
Engaging the Handbrake While Moving
Another common reason for stalling a car is when the handbrake is accidentally engaged while the vehicle is in motion. This can happen if the driver forgets to release the handbrake before attempting to drive off, causing resistance and strain on the engine.
Tips to Avoid This
Always ensure that the handbrake is fully released before moving off. Develop a habit of checking for any obstructions or indicators of the handbrake being engaged before starting the vehicle.
Running Out of Fuel
Running out of fuel is a straightforward yet often overlooked cause of car engine stalling. When the fuel tank is empty or near empty, the engine may sputter and stall, leaving the driver stranded.
Tips to Avoid This
Regularly monitor the fuel gauge and refill the tank before it reaches critically low levels. Make it a habit to refuel when the tank is around one-quarter full to prevent car damage due to fuel shortage.
