Questions and Answers

Why do minivans like the Carnival and Sedona require heavy-duty radiator construction?
Minivans frequently carry heavier passenger loads and are often utilized for towing, which generates high sustained thermal loads on the engine and transmission. The 25310-4D800 features an enhanced core design to manage these higher operating temperatures safely.
Do towing packages or rear AC systems affect radiator selection?
Yes. Models equipped with heavy-duty cooling packages or auxiliary rear climate control configurations may utilize different transmission oil cooler line connections or alternate bracket placements on the radiator tanks. Providing your VIN ensures your transmission lines connect without modification.
How often should the coolant be changed on a VQ platform V6 engine?
For optimal longevity of your radiator and water pump, it is recommended to flush and replace the coolant every 40,000 to 50,000 kilometers, or according to your owner's manual guidelines, using manufacturer-approved long-life coolant formulations.
