Radiator, heater, intake and vacuum hoses endure heat, pressure pulsation and ozone every day, and they age over time. During routine maintenance, check for these five signs:
- Hard or brittle: squeeze the hose when the engine is cool — if it has lost its elasticity, the rubber has aged;
- Soft spots or bulges: a spongy feel or swelling usually means the inner tube or reinforcement is damaged;
- Surface cracking: fine cracks on the cover are typically caused by ozone and heat aging;
- Leaks or deposits at the ends: coolant traces or white/green crystals near the clamps;
- Abrasion: rubbing against nearby parts thins the cover or even exposes the reinforcement.
Replacement tips
Choose a replacement that matches or exceeds the original specification, and check clamps for corrosion or loss of tension. For turbocharged engines, intercooler lines run hot and pressurised — consider upgrading to multi-ply silicone hose.
