An overheated engine is no joke—warped heads and blown gaskets cost thousands. Your radiator is the first line of defense.
Coolant chemistry: Antifreeze mixes (green, orange, or pink) contain inhibitors to prevent corrosion and raise boiling points . Manufacturers recommend a flush every 30k–50k miles .
Warning signs:
- High temp gauge
- Steam or sweet smell of leaking coolant
- Sludgy coolant under the cap
Inspect hoses for cracks or bulges every oil change, and replace the radiator cap every few years to maintain proper system pressure .
A little radiator love now avoids the drama of a stranded-on-side-of-the-road meltdown later.
