Frequently Asked Questions
Will this radiator fit without modifying my cooling system hoses?
Yes. This is an OEM replacement, so all factory connection points and hose fittings align directly with your original setup. No adapter fittings or modifications needed.
Do I need to flush the cooling system before installation?
Recommended. Flush your system with distilled water and let it drain completely before swapping in the new radiator. This clears out any sediment or debris that could clog the new core.
What about the water pump and thermostat—do they need to be replaced at the same time?
Not necessarily. Inspect those parts separately. If they're still functioning, leave them alone. Replace them only if they show signs of wear or leakage. This radiator works with your existing pump and thermostat.
