Frequently Asked Questions
Will this radiator work with my factory cooling fan and shroud?
This is an OEM replacement that mounts at factory points, but verify your existing fan and shroud are original or compatible — aftermarket cooling systems may have different fitment. Measure the core dimensions against your current setup before ordering.
Do I need to flush the system before installing this radiator?
Yes. Run a coolant flush to remove old debris and sediment, then refill with fresh 50/50 mix. A clean system prevents clogs and keeps your new radiator running at full capacity.
What about the transmission cooler lines — do I need to reuse my old connections?
The transmission cooler ports on this radiator accept standard hose fittings. Inspect your old lines for cracks or weeping — if they're compromised, new transmission cooler hoses are inexpensive insurance against leaks.
