Common Problems Detail:
The Northstar V8 engines are known for potential coolant leaks originating from the rear intake manifold crossover ('elbows'). This requires intake manifold removal for repair. Earlier models had potential for piston cooling jet failures, though less common by 2010. Check for HVAC blower motor resistor failures and climate control module issues.
