Frequently asked questions
I see green/pink liquid under my car in Hyderabad — is it coolant?
Yes — coolant (antifreeze) is typically green, pink, or orange and has a distinctly sweet smell. A puddle under the car near the front is usually a radiator or lower hose leak. A puddle under the engine center is often a water pump seal. Coolant on the passenger floor means heater core leak. If you see white powder deposits around any connection, that's dried coolant from a slow evaporative leak.
