Cadillac DeVille 9th Generation (G-platform)

20002005 · G-platform · sedan

The ninth-gen DeVille launched for 2000 on the redesigned G-platform, still FWD with a transverse Northstar. Trims were DeVille, DHS (DeVille High Luxury Sedan), and DTS (DeVille Touring Sedan). All used the 4.6L Northstar DOHC V8: the LD8 (275 hp, DeVille/DHS) or L37 (300 hp, DTS). 4T80E four-speed automatic. The DeVille nameplate was retired after 2005; the 2006 DTS continued on the same platform as a renamed successor.

Watch out: Owner reports of Northstar head-bolt thread pull (the head bolts strip out of the aluminum block, causing head-gasket failure and coolant loss) are the defining long-term issue. Time-Sert thread inserts during head-gasket replacement are the standard fix.

Full clubhouse — owner Garage Lineage, common problems, year-by-year notes, and product picks — is on the build list.
