Why Monsoon Prep Cannot Wait Until the First Downpour
It is the same scenario year after year in Pakistan. When the first big monsoon rain falls on Lahore or Karachi, a few hours later the local workshops are filled with vehicles having dead batteries, broken brakes, and wipers that cater to the eyes more than the road. All of these problems could have been averted most of them were.Most of these problems could have been averted and most of them were.
The monsoons in Pakistan are indeed challenging for vehicles. The underpasses are flooded, driving conditions are slippery, humidity is high and the rain is torrential it's a harsh environment for under-maintained underpasses. Fortunately, an afternoon of checks can make a huge difference when it comes to preventing getting stuck, getting into an accident and having to pay through the roof for the repairs when the rain comes. Here are 7 tips every Pakistani driver should follow today before the first heavy rain sets in.
1. Tyre Tread and Pressure Before the Roads Get Slippery
Your tyres are the only link between your car and the road – and on a wet road, the difference in tyres becomes even more significant. Tyres that are worn reduce your chances of not losing traction with the road when you get caught in a layer of water and lose steering and braking control.
Use the one rupee coin test to check the tread depth. The top of the crescent on the coin must be covered by the tread, if not, replace the tyres before the monsoon season.
Examine all four wheels (including the spare) and ensure they are inflated to the correct pressure as stated in the owner's handbook. This is a quick but important test as under inflated tyres have the same effect on roads as worn tyres.Â
2. Wiper Blades and Washer Fluid for Real Visibility
 Heavy rain makes it hard to see and your wipers do more than you think to keep you safe. Wiper blades on many cars enter the monsoon season with cracks and streaks in their rubber, which results in them not effectively wiping the windshield thoroughly.
If you see streaks, skips, or cracks in the rubber, replace the wipers. This is one of the least expensive safety upgrades and is a good one to make periodically, if not annually. Fill the washer fluid reservoir and use a rain-repellent or anti-fog washer fluid additive in case of sudden rain for better visibility. Test your wipers on a dry day ahead of time, instead of during a storm.Â
3. Brake System Health Before You Need to Stop Fast
Even the weakest brake system is much more hazardous when the rain begins, and braking distance is much greater on wet roads. Rust can form on brake discs and brake fluid can become contaminated by moisture, which will diminish braking performance when you need it most.
Before the rainy season, get your brake lines, discs, and brakes checked by a certified mechanic. When the vehicle pulls to one side or vibrates while braking, it may be due to uneven tire wear or water getting in that should be dealt with now. There are many service centres in Pakistan that provide their service just for monsoon brake checking, and you should avail of their services before actually facing rains in the real world.
4. Battery and Electrical System Against Moisture
Car batteries and electrical systems are very vulnerable to the monsoon air and moisture. There's nothing more frustrating than a battery that's slowly gone bad all year long taking the plunge at the worst possible time, such as after it's rained and the road is flooded.
Why Corroded Terminals Cause Sudden Breakdowns
It creeps up in the battery terminal and is only recognized when the moisture increases the corrosion during the monsoon season. The resulting corrosion of terminals, in combination with water ingress, often leads to failures to start or to complete electrical shutdowns at the most inopportune moments.
Get your battery tested now, especially if it is older than two years. Check the terminals for visible corrosion and apply a thin layer of petroleum jelly to protect the connections from moisture. Inspect your wiring insulation and fuse box for any signs of wear, since water exposure to damaged wiring can short circuit headlights, indicators, or other essential systems exactly when you depend on them most.
5. Rubber Seals, Drains and Rustproofing
Water can enter the car through the smallest cracks and in Pakistan's monsoon climate, where there is plenty of water, rust is formed wherever water accumulates. This is one of the most forgotten parts of monsoon car maintenance Pakistan drivers neglect to do.
Check the rubber weatherstripping around your doors, trunk and sunroof for cracking or deterioration, as damaged seals allow water to flow right into your cabin. If the seal is still in good condition, clean it and spray it with silicone lubricant to maintain the rubber's flexibility and seal. Often leaves and debris will get stuck in the drain holes at the bottom of your doors and windshield cowl, so use a flexible wire to remove anything blocked and a lead to drain, as it will cause mold and electrical issues when it backs up.
If your vehicle doesn't have one, you may want to get an underbody rust proofing treatment. In Pakistan's damp and muddy monsoons, rust is a very serious and rapidly progressing problem, especially on the underside of the vehicle, wheel wells and where any metal is exposed, so this is a very worthwhile preventative purchase.Â
6. An Emergency Kit That Actually Helps
Despite the best efforts, monsoon emergencies occur. A good emergency kit can help you avoid a crisis, and make a stressful breakdown more manageable.
Your kit should contain reflectors (triangles or LED flares), a flash light and extra batteries, tow roping, a waterproof poncho, a first aid kit, and a roadside stop stick. Take a tyre inflator and some basic tools, and a waterproof bag with photocopies of car documents and insurance papers. Remember to keep the tank filled above 50% during monsoons as refueling may become difficult during heavy rain due to queues at the fuel stations.
7. A Plan for Flooded Roads Before You Face One
Tackling the task before you get to the standing water is the difference between a safe outcome and ruined engine. There are a lot of people who make very serious errors in judgment without even considering what to do when.
The Bow Wave Technique and the Golden Hydrolock Rule
When the water's level is level with or below the centre of the wheel when you look at your car from the side, drive gently in low gear to generate a small bow wave ahead of your car. This helps to keep water away from your engine bay and minimize chances of water getting into the air intake, which can have a negative effect on your engine. After leaving water, do not stop, as stopping would permit water to equalise around your car, and cause water to enter the exhaust pipe, causing the engine to stall.
If your engine does stall in water, the one golden rule is to not try and start it. If the engine has stalled in flood water, the engine may have suffered “hydrolock” and restarting the engine will result in serious damage. Turn on your flashers, move to safety and call for towing service.
Frequently Asked Questions (FAQs)
How do I know if my tyres are safe for monsoon driving?
Use the one-rupee coin test on your tread. If the tread does not cover the top of the crescent, your tyres need replacing. Always check tyre pressure as well, since both worn tread and incorrect inflation increase your hydroplaning risk significantly.
What should I do if my car stalls while driving through flooded water?
Do not attempt to restart the engine. This is the most important rule in monsoon driving. A stalled engine in deep water likely means water has entered the engine itself, and restarting can cause serious, expensive damage.
How often should I check my car battery during monsoon season?
Test your battery before monsoon season begins, especially if it is more than two years old. Humidity and water exposure significantly increase the risk of sudden battery failure, so proactive testing is far better than dealing with an unexpected breakdown.
Is rustproofing really necessary for monsoon car care in Pakistan?
Yes, particularly in humid and coastal areas like Karachi. Underbody rustproofing and cavity wax treatments protect your car's metal body from the accelerated corrosion that Pakistan's monsoon conditions cause, and the cost is far lower than dealing with structural rust damage later.
Don't wait for the first downpour to find out what needs fixing. Book a complete monsoon readiness check with Harriscarcare and drive into this rainy season with confidence.
