The L52 (also called Vortec 3500), is a straight-5 truck engine. It displaces 3.5 L (3,460 cc/211 cu in), with a 93 mm (3.7 in) bore and 102 mm (4.0 in) stroke, and shares much with the rest of the Atlas family. Dynoed at the flywheel it produces 220 hp (164 kW) at 5600 rpm and 225 lb·ft (305 N·m) at 2800 rpm, while producing 179.13 hp at 6001 rpm when dynoed at the rear wheels. Engine redline is 6300 rpm. These engines have a known issue: The valve seats of the intake valves allow some exhaust gasses to travel back out the intake valve, causing a misfire condition. GM issued a recall to replace the cylinder heads on models triggering the specific problem code.
It is used in the following vehicles:
- 2002 Bel Air concept
- 2004–2006 Chevrolet Colorado
- 2004–2006 GMC Canyon
- 2006 Isuzu i-Series
- 2006 Hummer H3
