Buy Nissan Maxima Radiator Support

The support forms the front "backbone" of the car. It anchors the radiator and fans so coolant can flow without vibration. (Wikipedia)
It also squares up the fenders, bumper cover, and grille so body panels fit right and don't buzz or rub. (WardsAuto)

Every generation of Maxima (1989-present) uses a unique core support; 2000-2003 (A33) and 2004-2008 (A34) units are not interchangeable with 2009-2014 (A35) or 2016-2023 (A36) versions because mounting holes, head-lamp brackets, and hood-latch height changed. Always match the support to the exact model year and engine size before ordering. (NICOclub)

Older Maximas use stamped high-strength steel that can rust if paint is chipped. (NICOclub)
Newer cars, like the 2016-2023 A36, add aluminum cross-tubes to save weight, and some luxury models even switch to magnesium or composite pieces for lighter crash structures. (Wikipedia, WardsAuto)

• Rust-out: Salt and moisture collect in the lower tie-bar and eat the metal from the inside. (Reddit, Maxima)
• Crash bends: Even a low-speed impact can tweak the support and push the radiator into the fan. (YouTube)
• Mount fatigue: Bolts loosen over time, causing rattles or cracked welds. (NICOclub)

• Hood no longer lines up with fenders.
• Radiator or A/C condenser sits crooked and vibrates.
• Coolant leaks at the side tanks after a bump.
• Headlights won't aim correctly.

All of these point to a bent or corroded front cradle. (Reddit, NICOclub)

The support works with bumper beams and crush zones to absorb crash energy and help keep the engine out of the cabin. Modern designs even factor in pedestrian-leg impact space and energy-absorbing plastic stiffeners. (ResearchGate)
Because of this, straightening a badly bent support is risky-it may not protect the same way twice. Replacement is the safer route. (WardsAuto)

1. Disconnect battery and drain coolant.
2. Remove grille, bumper cover, headlights, and hood latch.
3. Support engine with a transverse bar; Nissan service bulletins show placing a wood block on the upper core support to carry the third leg.
4. Unbolt or drill out the spot-welds holding the old frame. (NICOclub)
5. Test-fit the new piece; check gap at hood and fenders.
6. Bolt or weld per factory seam-seal pattern; paint bare metal.

A weekend mechanic with basic tools can swap an upper tie-bar; full frame-style supports usually need welding and professional alignment. (YouTube, NICOclub)

• Rinse the lower cradle after winter.
• Spray wax-based cavity sealer inside boxed sections.
• Keep splash shields intact to block road salt. (Maxima)

• Check mounting bolts and rubber isolators at every oil change.
• Replace worn hood-latch screws; a loose latch can tear the support sheet metal. (NICOclub)
• Inspect for paint chips and touch them up right away.

Lightweight aluminum or composite aftermarket cores shed a few pounds and resist rust, but always pick units that meet crash and hood-latch load specs published by the maker. Some kits include integrated fan shrouds for smoother airflow. (WardsAuto)

Q: What does a radiator support do on a Nissan Maxima?
A: It holds the radiator, A/C condenser, hood latch, headlights, and bumper cover in the right spots and keeps the front end strong in a crash. (Wikipedia)

Q: How can I tell mine is bad?
A: Look for rust holes, bent metal, crooked hood gaps, or a radiator that shakes while idling. (NICOclub)

Q: Can I drive with a broken core support?
A: It is not safe. A loose radiator can leak and the hood latch may fail in a collision. Replace it as soon as possible. (ResearchGate)

Q: Is welding required?
A: Upper tie bars often bolt in; full assemblies usually need spot-welds, just like the factory, to restore strength. (NICOclub)

Q: Why do these parts rust so much?
A: Road salt and water sit in the hollow lower beam with little drainage, eating the steel from the inside out. (Reddit, Maxima)

Q: Are aluminum versions better?
A: They resist rust and weigh less, but they can be harder to repair if bent. (Wikipedia)

Q: How long does replacement take?
A: A skilled DIYer can swap an upper tie-bar in 3-4 hours; a full frame with welding may take a shop a full day plus paint time. (YouTube, NICOclub)

Q: Do I need to remove the engine?
A: No. Nissan's own bulletin shows using an engine support bar so the motor stays in place while the cradle is out.

Q: Will my radiator overheat if the support is bent?
A: Yes. Misalignment blocks airflow and can crack plastic end tanks, leading to overheating. (Wikipedia)

Q: Should I coat the new support?
A: Yes-apply epoxy primer inside seams and add cavity wax after paint for the best corrosion defense. (Maxima)
