I should have said the bonding between the passage tubes and the fins can break down, causing a lack in ability of the radiator to transfer heat from the coolant to the tubes and out to the fins. Bottom line, aluminum radiators will lose efficiency after about 5 years. An aluminum cleaning solution will take the oxide off the fins, which are on the outside of the radiator. Semi-truck mechanics will use aluminum trailer cleaner to wash this oxide coating off, and swear by the stuff, and swear by the practice of using it, but that only solves part of the problem, if the bonding is suffering. Turning off your AC always helps. ADOT has signage that reads, “Turn OFF Your AC” on the steep grades heading north out of Phoenix Arizona. We have a pretty good 6% heading up to Sunset Point, and the road up to Payson has some steep grades too. You go from 1000 feet above sea level to 7000 feet in just over an hour, heading north on I-17 with 3 deep valleys in between. If your temperature gauge starts to climb, turn off the AC and turn on the heater. The heater core is like a miniature radiator, and it will help cool the engine. The passengers will not be to comfortable, but walking in the hot sun, is even more uncomfortable.

You could have combustion gases leaking into the cooling system from a bad head gasket, or a bad torque converter can cause the transmission fluid to heat up the cool side of the radiator in radiators with automatic transmission coolers inside them. If it is a “marginal problem” like pulling prolonged uphill grades, a new radiator can also do the trick. You can have no leak, and no flow issues, but over time the aluminum in the radiator oxidizes, and that aluminum oxide is a pretty good thermal insulator, so the air passing over the fins will not take away a much thermal energy (heat). The bonding between the liquid passage tubes can also be mechanically compromised, taking away the radiator’s efficiency too.
