The following diagnosis might be helpful if the vehicle exhibits the symptom(s) described in this PI.

Some technicians may wonder why the parts catalog has a user note next to Goodwrench® engine part number 89017835 that states - "When used for 2004-2005 applications, the exhaust camshaft position actuator must be changed to 2004-2005 content."

They may also wonder why the engine comes with an instruction sheet that states - "This Goodwrench Engine Assembly is for use on 2004-2006 In-line 4 Cylinder 2.8L (LK5) equipped vehicles. For all 2004-2005 applications, the Exhaust Camshaft Position Actuator Assembly must be changed to 2004-2005 content. Reference service manual repair instructions for proper replacement procedures."

A 2006 model year 2.8L engine will be received if a 2.8L Goodwrench® engine (Part Number 89017835) is ordered for a 2004 - 2005 Canyon or Colorado. The 2006 model year 2.8L engines use a vane style exhaust camshaft position actuator instead of a spline style actuator like the 2004 - 2005 2.8L engines use. The vane style exhaust camshaft position actuator is different than the original spline style actuator. As a result, the exhaust camshaft position actuator must be changed to 2004 - 2005 content before a 89017835 Goodwrench® engine is installed in a 2004 - 2005 Canyon or Colorado.
