1. Prevent engine overheating

• Dissipates heat from hot coolant

• Keeps engine temperature within safe operating limits

2. Improve cooling efficiency

• Aluminum transfers heat quickly

• Multi-row aluminum cores increase airflow and heat rejection

3. Reduce vehicle weight

• Lighter than copper/brass radiators

• Helps improve fuel efficiency and performance

4. Increase durability

• Resistant to corrosion and rust

• Handles high temperatures and pressure well

5. Support performance upgrades

• Ideal for turbocharged, supercharged, or high-RPM engines

• Maintains stable temperatures under heavy loads

1. Engine overheating

• Temperature gauge running high

• Overheating warning light

• Overheats especially in traffic or under load

2. Coolant leaks

• Puddles of coolant under the vehicle

• Low coolant level without visible engine leaks

• Leaks from radiator seams, tanks, or welds

3. Discolored or damaged radiator

• Corrosion, white powdery residue, or staining

• Bent or clogged fins reducing airflow

• Visible cracks in the core or end tanks

4. Coolant contamination

• Rust, debris, or oil mixed in coolant

• Sludge buildup inside the radiator reducing flow

5. Poor heater performance

• Weak or no heat from cabin heater

• Indicates restricted coolant flow

6. Frequent coolant top-offs

• Coolant level drops repeatedly

• Indicates slow leaks or internal blockage

7. Steam or sweet smell

• Steam from engine bay

• Sweet smell of coolant after driving
