Can I keep topping up coolant without fixing the leak?
Topping up coolant only masks the leak and does not fix it. Continued coolant loss leads to overheating and head gasket failure. It also dilutes the coolant mixture, reducing freeze and boil protection. Fix the leak when it is first noticed — a ₹5,000 hose fix today avoids a ₹75,000 head gasket job later.
