Frequently Asked Questions
Will this radiator fit both manual and automatic transmission trucks?
Yes. This unit is designed to work with both transmission types across the 3.4L and 4.0L engine range without modification.
Do I need new hoses and clamps, or can I reuse the old ones?
Old hoses and clamps can shift over time. We recommend fresh hoses and clamps during installation — they're inexpensive insurance against leaks down the road.
Can I install this myself, or do I need a shop?
Installation is straightforward if you're comfortable draining coolant and unbolting the factory unit. Drain your system into a clean container, unbolt the old radiator, swap in the new one, and refill. A jack, basic wrenches, and a coolant catch pan are all you need. Bleed air from the system per your service manual.
