HIGH QUALITY GENUINE OEM, AFTERMARKET SPARES
Your car radiator is a key part of the cooling system that keeps the engine at a safe temperature. In India’s hot climate, radiator problems are a frequent cause of breakdowns. Drivers often search for answers to questions like why the car is overheating, how to tell if the radiator is bad, how long a radiator lasts, and what a replacement might cost. This guide brings all of those answers together so you can decide when to repair, flush, or replace the radiator with genuine spare parts.
A radiator can develop issues over time due to wear, heat, and neglected maintenance. Early detection helps you avoid expensive engine repairs.
Old coolant can turn acidic and damage internal passages and metal fins. Corrosion weakens the radiator and reduces heat transfer.
Flush the radiator every 40,000 to 60,000 km or every 3 years. Fresh coolant protects against rust and keeps the system clean.
Leaks from hoses, clamps, seals, or the radiator body cause low coolant levels and lead to overheating under load or in traffic.
Inspect hoses for soft spots, cracks, or swelling. Refit quality clamps and replace worn parts with OEM components for a reliable seal.
Dirt and debris on the fins restrict airflow. Internal deposits can also clog tubes and slow coolant flow through the core.
Clean the fins gently to restore airflow. If the core is internally clogged or damaged, replacement is the practical solution.
Air pockets after a coolant change or due to a leak can block circulation and cause hot spots that trigger overheating.
Bleed the system to remove trapped air. Many cars have a bleeder valve. If not, a mechanic can bleed the system during servicing to restore normal flow.
Frequent overheating often points to a weak radiator, low coolant levels, airlocks, blocked fins, or poor circulation from a worn water pump. Continuous overheating risks head gasket damage and costly repairs. For a broader view of every possible cause and practical roadside steps, read our complete guide on why car engines overheat.
With normal use and proper maintenance, many radiators last 8 to 10 years. City traffic, high ambient temperatures, and highway runs can shorten that figure. Regular flushes and timely hose replacement help extend service life.
In India, typical radiator replacement costs range from ₹8,000 to ₹15,000 depending on the car model, part quality, and labour charges. Choosing genuine spare parts provides consistent cooling performance and better durability compared to unknown parts.
A healthy radiator protects the engine and keeps your drives smooth and stress free. Watch for leaks, rust, airlocks, and blocked fins. Maintain coolant levels, follow flush intervals, and replace worn hoses or the radiator before problems escalate.
