Common questions
Can a radiator be repaired?
Small leaks may be patched, but most shops replace the radiator because repairs often don't last.
What causes a radiator to fail?
Age, rust inside from old coolant, road salt outside, and plastic end tanks that crack with heat cycles. A rock or fender bender can also puncture it.
Why is coolant added?
The old coolant drains out during the repair, and the new radiator needs fresh fluid with air bled out.
