All 1 Known Issues
On the 1993-2004 Cadillac Seville Northstar 4.6L, the Northstar V8 in the Seville shares the same head gasket failure as all Northstar-equipped vehicles. The aluminum block head bolt threads strip, reducing clamping force on the head gaskets. This allows combustion gases to enter the cooling system and coolant to enter the cylinders. The issue is virtually guaranteed on high-mileage Northstars.
Common Symptoms
- Overheating
- Coolant loss
- White exhaust smoke
- Bubbles in coolant tank
- Rough running engine
How to Fix
The industry-standard repair uses Time-Sert inserts to repair the head bolt threads in the aluminum block with stronger steel threads. This can be performed with the engine in the vehicle. Use updated MLS head gaskets and proper torque specifications. Budget $2,500-$4,000 for this repair at a shop experienced with Northstars.
