Radiators & Parts

Stop Overheating Problems with a Quality Radiator

Any automobile aficionado knows there's plenty of options when buying car parts online, but INFINITI of Tucson is the best. Your radiator removes heat from engine coolant by passing it through thin metal tubes surrounded by cooling fins while air flows through from the front grille. Without a functioning radiator, your engine overheats within minutes and can suffer catastrophic damage including warped cylinder heads and blown head gaskets. A leaking or clogged radiator leaves you stranded on the roadside and leads to repair bills that dwarf the cost of timely replacement.

How Radiators Fail Over Time

Radiators deteriorate through corrosion, physical damage, and clogging from contaminated coolant over their service life. Internal corrosion eats away at thin metal tubes when old coolant loses its protective additives and becomes acidic. External corrosion attacks aluminum fins and metal tanks when road salt spray contacts the radiator surface repeatedly. Plastic end tanks crack from constant heating and cooling cycles that cause expansion and contraction stress. Impact from road debris or minor front-end collisions punctures cooling tubes and creates leaks that drain coolant rapidly. Clogged passages develop when rust particles, scale buildup, and deteriorated hoses deposit material inside narrow tubes. Transmission coolers integrated into many radiators fail and allow transmission fluid to contaminate the cooling system. Mounting brackets corrode and break, causing radiators to shift position and stress connected hoses. Most radiators need replacement between 80,000 and 120,000 miles depending on maintenance history and coolant change intervals.

Why Genuine INFINITI Radiators Perform Better

Aftermarket radiators use thinner tubes and fewer cooling fins, reducing heat dissipation capacity below factory specifications. Genuine INFINITI radiators maintain exact dimensions for models like the Q50 and QX60, ensuring proper fitment with mounting points and belts and hoses connections. Generic parts arrive without integrated transmission coolers or use inferior plastic that cracks prematurely. We stock authentic radiators built to original equipment standards with proper tube count and cooling capacity for your specific engine.
