Cadillac DeVille 8th Generation (K-platform)

1994–1999 · K-platform · sedan

The 1994 DeVille moved to GM's K-platform, the same FWD luxury platform as the contemporary Seville. The 1994 base DeVille briefly carried over the 4.9L L26 OHV V8 (200 hp), but for 1996 the Northstar 4.6L L37 (DeVille Concours) and LD8 (base DeVille) DOHC V8 became standard across the lineup. 1994-1995 base DeVilles can still be found with the L26; from 1996 onward it is Northstar-only. Four-speed automatic (4T80E). Replaced by the 9th-gen DeVille for 2000.

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