Motul India Top 5 Signs Your Vehicle Needs a Coolant Change Your engine works hard, and one of the most overlooked aspects of its health is the coolant. It doesn’t just prevent overheating — it helps maintain optimal engine temperature, protects metal components from corrosion, and improves overall efficiency. But like any other fluid, coolant degrades over time. Here are five clear signs it's time to flush and replace your radiator coolant, ensuring your vehicle stays in peak condition 1. Rising Engine Temperature One of the earliest indicators is a steadily increasing temperature gauge. If your engine warms up faster than usual or overh eats during normal driving, degraded coolant for car systems could be the cause. It may no longer be circulating effectively or ha s lost its thermal properties. 2. Sweet or Pungent Smell from the Engine Bay Coolants often have a sweet scent due to ethylene glycol. If you notice this smell near your car, it might be a sign of a rad iator coolant leak. Addressing it early can prevent costly engine damage and loss of performance. 3. Discoloured or Dirty Coolant Over time, even the best coolant in India will accumulate rust, debris, or oil, turning murky or brownish. If your coolant is n’t bright and clean, it’s time to change it. Dirty coolant is less effective at regulating temperature and can corrode internal parts. 4. Poor Heater Performance in Cold Weather If your cabin heating isn’t working well, it could be due to low or old coolant. The same fluid that cools your engine also s upports the heater core. Replacing worn - out coolant ensures year - round comfort and function. 5.
