These tools are for aligning the camshafts on 3.6L 3.0L V6 engines (pre SIDI) while performing any work on the engine such as replacing timing chains. When setting the camshaft timing, due to the engine having separate timing chains going to each bank of cylinders, the camshafts on the left bank must be held while setting the timing on the right bank and vice versa.

 

Failure to use these tools can result in incorrect camshaft timing due to the camshaft moving under spring pressure from valve springs which can consequently cause engine damage.

 

Note: This product can also be used for 3.6L Alloytec V6 engines by simply using only two of the tools instead of three - use plate A and Plate B.
