The monsoon is the hardest season of the year on an Indian car. Waterlogged roads, invisible potholes, fogged-up windscreens, and constant damp all attack parts that coped fine in summer. A quick pre-monsoon service — done before the heavy rain sets in — costs a fraction of what a monsoon breakdown or a skid does. Here are the nine things worth checking, and what each should cost in 2026.
1. Wipers and washer fluid
Cracked or juddering wiper blades are the number one monsoon complaint. A quality pair of blades costs ₹400–₹1,200 fitted. Top up the washer reservoir and add a screen-wash additive to cut through road grime. This is the cheapest safety upgrade you can make before the rains.
2. Tyres — tread and pressure
Bald tyres and wet roads are a deadly combination. You need at least 2–3 mm of tread to clear water and avoid aquaplaning. Run the simple coin test; if the tread is low, budget ₹4,000–₹6,000 per tyre for a mid-range brand. Also get pressures checked — many owners run under-inflated, which worsens grip. See our tyre service cost guide for brand-by-brand pricing.
3. Brakes
Wet brakes fade and squeal, and worn pads are dangerous in stop-go monsoon traffic. Have the pads and discs inspected; a front brake-pad replacement runs ₹1,800–₹2,800 at an authorised centre, less at a good independent. Do not postpone this one. Full pricing is on our brake service cost page.
4. Battery and terminals
Humidity accelerates terminal corrosion, and headlights, wipers, blower, and defogger all run at once in the rain — a heavy electrical load. If your battery is over three years old, get it load-tested. A replacement costs ₹4,500–₹6,500; see the battery replacement guide for options.
5. AC and demister
Your AC is not a luxury in the monsoon — it is what keeps the windscreen clear. A clogged cabin filter or weak AC leaves you peering through fog. An AC check and cabin-filter change costs ₹800–₹2,000; a full AC service is more. Details on our car AC service cost page.
6. Headlights, tail lights, and indicators
Visibility drops sharply in heavy rain, so every bulb matters. Check all exterior lights and replace any that are dim or out — usually ₹150–₹800 per bulb. Fogged or cracked lamp housings let water in and should be resealed.
7. Underbody and rust check
Standing water and mud accelerate rust, especially on the underbody and wheel arches. A pre-monsoon underbody wash and anti-rust check is cheap insurance — ₹500–₹1,500. If you regularly drive through waterlogged areas, ask about underbody coating.
8. Rubber seals and door drains
Blocked door and sunroof drains are how water ends up pooling in footwells and rotting the carpet. Clearing them takes minutes and is often free during a service. Check that door and boot rubber seals are intact so cabin damp does not set in.
9. Electricals and central locking
Damp plays havoc with modern car electronics. If you have had flickering lights, a temperamental central lock, or dashboard warnings, sort them before the rains rather than during. Water ingress into a fuse box or connector is far more expensive to fix once it has happened.
What the whole check should cost
A basic pre-monsoon inspection with wiper blades, a cabin filter, and fluid top-ups typically runs ₹2,500–₹4,500. If you also need tyres, brakes, or a battery, it climbs — but every one of those is a safety item you would replace anyway. The point of doing it now is to avoid a breakdown on a flooded road, which costs far more in towing, damage, and stress.
