Frequently Asked Questions
Do I need to drain and flush the cooling system before installation?
Yes. Drain the old coolant completely, flush the system to remove debris, and refill with fresh coolant rated for your LS430. This ensures optimal heat transfer and prevents corrosion in the new radiator.
Will this radiator work with my existing hoses and clamps?
Factory hose connections are preserved on this OEM radiator. Check hose condition before install — if they're cracked, hardened, or leaking, replace them now rather than later.
Do I need a new thermostat when I install this radiator?
Not required, but common practice. If your thermostat is original or over 10 years old, replacing it during this job prevents follow-up cooling issues. Your call based on condition.
