Engine Block

WARNING: This page is about a different car, the 2007 Saturn Vue. However, it is still accessible from the selected car via links, so may be relevant.

The cast aluminum V-shaped engine block is a deep-skirt design with 4 main bearing caps. The iron cylinder liners are a cast in place design. Coolant jackets encircle the cylinders. The 4 cast-iron bearing caps are cross-bolted to the engine block and each are retained by 2 vertically and 2 horizontally located bolts. Right side cylinders are numbered front-to-rear as 1-2-3. Left side cylinders are numbered front-to-rear 4-5-6. The firing order is 1-4-2-5-3-6.
