What causes Car Cooling System Flush?
These are the faults we most often find behind this symptom on cars driven in Hyderabad's heat and stop-go traffic:
- Old coolant (over 2 years) losing anti-corrosion additives — scale builds in radiator
- Wrong coolant type mixed — different colours react and form gel deposits
- Tap water used instead of distilled water — scale deposits block radiator passages
- Engine thermostat needs replacement during coolant service
- Heater core partially blocked from coolant sludge

Frequently asked questions
How often should coolant be changed in Hyderabad?
Engine coolant should be changed every 2 years or 40,000 km in Hyderabad — the hot climate accelerates additive depletion faster than cooler regions. Signs of old coolant: rust-brown colour (instead of green/blue/red), acidic smell, visible scale deposits in the reservoir cap. Metre Per Second uses OEM-recommended coolant grades — Maruti Blue, Honda Blue, Volkswagen G13, Toyota pink (SLLC) — never mixing types.
