Frequently Asked Questions
Do I need new coolant or hoses when I swap in a new radiator?
Flush the cooling system before installing this radiator. Hoses typically last longer, but if yours show cracks or soft spots, replace them now — you're in there anyway. Fresh coolant prevents corrosion inside the new core.
Can I install this myself or do I need a mechanic?
It's a weekend job if you're comfortable draining coolant and unbolting radiator brackets. You'll need a drain pan, basic sockets, and patience. If you're unsure about air pockets in the cooling system after refill, have a shop burp it for you.
What's your return window if this doesn't fit or function?
Check the listing return policy for your region. Test fit it immediately after delivery — don't wait until it's installed and filled with coolant. We back up what we sell, but early verification saves everyone time.
