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?
Contact ModSupply directly with photos and order details. We stand behind every unit that leaves our warehouse — a quality check and Florida facility mean fast resolution if something's wrong.
