Buy Buick Lucerne Grilles

Below is a detailed, easy-to-read guide covering every angle of the Buick Lucerne grille-sometimes called the front grill, radiator grille, front fascia grill, or grill assembly.

Overview

The Buick Lucerne sedan was built for model-years 2006-2011, and every trim (CX, CXL, CXS, Super) wears a wide, vertical-bar "waterfall" grille that frames the tri-shield emblem and dominates the nose of the car. (Wikipedia) MotorWeek praised the design for giving the car a modern, premium look. (MotorWeek)

Design & Materials

Buick's waterfall pattern traces back to 1939 and is formed by closely spaced chrome-finished bars that resemble a flowing sheet of water. (Hemmings) The Lucerne's stock grille uses a molded plastic core that is chrome-plated for shine and weight savings, a common choice that balances cost and durability. Stainless-steel and mesh inserts are also popular upgrades because they improve airflow and resist rust. (zunsport.com)

Compatibility & Model Years

• 2006-2008: CX/CXL/CXS share one grille; the Super (introduced mid-2007) uses the same basic opening but carries a darker surround. (Wikipedia)
• 2009-2011 facelift: Small bumper tweaks mean a later grille can bolt onto an earlier car, but owners report needing matching bumper fillers for a perfect gap-free fit. (Buick Forums)
• A Lucerne grille will not interchange with other Buicks because its width and mounting tabs are unique to the G-body chassis.

Functions & Benefits

1. Airflow: The slotted pattern directs cool air to the radiator and A/C condenser while letting hot air exit under the car. (zunsport.com)
2. Protection: The bars stop stones, bugs, and road trash from striking delicate fins. (Wrangler TJ Forum)
3. Style cue: The shiny "waterfall" instantly signals a Buick-one reason the brand still uses the motif today. (devoebuickgmc.com)
4. Aerodynamics & cooling control: Some drivers add winter grille covers to help the engine warm up faster in extreme cold. (Motor Vehicle Repair Stack Exchange)

Common Problems

• Broken clips: Plastic tabs can snap if the car bumps a curb or during removal. (Buick Forums)
• Pebble cracks & chrome pitting: The low-slung position exposes the piece to debris and harsh winter salt.
• Loose emblem: Heat cycles can weaken the plastic welds that hold the tri-shield crest. Owners often reglue or replace it. (Buick Forums)

Removal & Installation

DIYers can swap the grille in 30-45 minutes without taking the bumper off:

1. Pop the hood and remove the upper radiator cover fasteners.
2. Use a trim-stick to depress each lower clip from above; work side-to-side until the assembly pops forward. (JustAnswer)
3. Transfer the emblem, seat the replacement grill, and push until all clips click. More detailed step-by-step photos are available on BuickForums. (Buick Forums)

Custom Upgrades

Owners often black-out the chrome with Plasti Dip, insert stainless mesh for a sport look, or repaint the bars to match body color. (Buick Forums) Mesh screens can boost strength and still let air through, provided the mesh size is not too tight. (Wrangler TJ Forum)

Maintenance Tips

• Wash gently with car-shampoo and a soft brush; rinse from the back side to flush sand.
• Apply liquid wax or sealant twice a year to slow chrome pitting.
• Check for leaves lodged behind the grill that can block air and raise engine temps.

Safety Tech

Higher-trim Lucernes (2008-2011) hide forward-collision and lane-departure cameras/sensors behind the grille emblem and upper bumper slots, so keep the area clean and free of solid overlays. (Wikipedia, NHTSA)

Heritage Notes

The dramatic 1950 "buck-tooth" Buick and later designs influenced the Lucerne's face, but the waterfall theme remained the brand's signature. (Mac's Motor City Garage) Today Buick still markets the narrow-bar waterfall as a key styling trait. (devoebuickgmc.com)

Frequently Asked Questions

Q: What years of Lucerne use the same grille?
A: 2006-2008 share one part; 2009-2011 share another, but both fit each other if the matching bumper fillers are used. (Buick Forums)

Q: Can I change the grille without removing the bumper?
A: Yes. Remove the upper radiator cover, release the clips, and pull the assembly forward. (JustAnswer)

Q: What tools do I need?
A: A plastic trim-stick, 10 mm socket for the cover bolts, and gentle hands to avoid snapping clips. (Buick Forums)

Q: Does a mesh insert hurt cooling?
A: Tests on similar setups show almost no temperature rise if the mesh is coarse enough. (Wrangler TJ Forum)

Q: Why is it called a "waterfall" grille?
A: The tight vertical chrome bars look like falling water-a Buick cue first seen in 1939. (Hemmings)

Q: Is it safe to block the grille in winter?
A: Partially blocking it helps engines warm faster in very cold climates, but remove the cover in mild weather to avoid overheating. (Motor Vehicle Repair Stack Exchange)

Q: What's behind the badge?
A: Certain 2008-2011 models mount the forward-collision radar and lane-departure camera behind the center badge and upper slots. (Wikipedia)

Q: My emblem is loose-how do I fix it?
A: Heat the plastic tabs from the back with a low-temp soldering iron to re-melt, or replace the crest and secure with automotive-grade epoxy. (Buick Forums)

Q: Will painting hurt resale?
A: A tasteful, chip-free finish usually doesn't, but keep the original grille so buyers can revert to factory chrome.

Q: Does the grille affect gas mileage?
A: Clean, un-blocked bars aid aerodynamics and engine cooling; a heavily clogged or blocked grille can increase drag and raise under-hood temps, trimming economy slightly. (zunsport.com)
