Frequently Asked Questions
12 FAQs on Korea monsoon car preparation.
Q1. How often should I replace wipers?
Every ~12 months (1 year). Sun and dust harden the rubber over time. If you see streaks or hear chattering, replace them immediately regardless of age. Replace both blades together for even performance.
Q2. What is the tire-tread wear limit?
Korean legal limit is 1.6mm, but in rain anything below 4mm dramatically raises hydroplaning risk. Use a 100-won coin upside-down — if Yi Sun-sin's hat is visible, you are around 2.8mm and should replace.
Q3. My A/C smells musty. What should I do?
Replace the cabin filter first (₩15,000-30,000). If it persists, the evaporator likely has mold — apply an antibacterial cleaner (₩20,000-50,000). Tip: turn off A/C 5 minutes before parking with fan on, to dry the duct.
Q4. How do I know my battery needs replacement?
Weak cranking, dim headlights at start, or age over 3 years. Have a shop run a CCA test for accurate diagnosis. Korean batteries last 3-4 years on average.
Q5. Should I start a flooded car?
Never. Cranking with water inside causes hydrolock — instant damage to connecting rods and cylinders, requiring full engine replacement (~₩3M+ for domestic cars). Call your insurer for a tow.
Q6. Does Korean auto insurance cover flooding?
Yes, comprehensive coverage (자차) includes natural-disaster damage including floods. Liability-only does not. The standard deductible is 20% of loss or ₩500,000, whichever is greater (₩0 deductible is an option).
Q7. A heavy-rain advisory is in effect and my car is in a semi-basement. What now?
Move it to high ground immediately. You typically have 30-60 minutes from advisory to road flooding. If roads are already flooded, abandon the car and evacuate yourself first. Cars are insurable, lives are not.
Q8. Can I replace wipers myself?
Yes, most cars take 5 minutes. Lift the arm, press the lock clip, slide off. Sizes are in your owner's manual or on retailer search tools. DIY costs ₩12,000-25,000, shop install runs ₩20,000-40,000.
Q9. Should I use hazard lights in rain?
No. Hazard lights are for stopped vehicles or breakdowns only. Using them while driving confuses other drivers about your lane intentions. Use headlights instead (even during day) and fog lights only when visibility drops below 30m.
Q10. What is a safe speed in heavy rain?
Korean law mandates 20% reduction below the posted limit on wet roads, 50% in heavy rain (above 20mm/hour). Hydroplaning risk rises sharply above 80km/h on water-pooled roads.
Q11. How do I avoid flood-damaged used cars?
Check car365.go.kr for free flood history by license plate. Inspect under seats, trunk, and door seals for mud, rust, or mold — all signs of past flooding. Buy from certified pre-owned programs with warranty for safety.
Q12. Where can I get pre-monsoon car inspections?
OEM dealer service (Bluehands, AutoQ), Hankook T-Station, Kumho Tire Pro all run seasonal packages. Generic shops are fine for wipers and tires. Late May to early June is the least crowded period.
