Frequently Asked Questions

Do I need new hoses or clamps when installing this radiator?

Your existing hoses and clamps will reuse if they're in good condition. Inspect them during removal — if they're cracked, swollen, or hard, replace them at the same time. Coolant system work often reveals hose wear you'd catch anyway.

Will this radiator work with my current coolant, or do I need to flush the system?

A flush is recommended when swapping radiators to remove sediment and old coolant. Use the coolant type specified in your owner's manual — Toyota systems typically use their own blend or equivalent long-life coolant. Don't mix types.

What if the radiator leaks or fails after I install it?
