Frequently Asked Questions
Will this drop in without modifying my engine bay?
Yes—it mounts at factory rocker points and uses original attachment locations. No drilling, fabrication, or bracket work needed.
Do I need to flush my cooling system before installing this?
Flushing isn't included in what ships with the radiator, but it's smart practice before any radiator swap to remove old coolant and debris. Your owner's manual outlines the flush procedure.
Which engine size do I need — 3.4L or 3.8L?
Check your vehicle's engine bay or owner's manual for displacement. Both radiators fit the same chassis, but they're sized differently for each engine's cooling demand—order the correct one for your specific powerplant.
