As this is a service engine, you will have to transfer over existing sensors, harness, and balancer from your original L84. We recommend a new balancer bolt # 11547372. It is also a recommendation to replace the oil cooler and lines if the previous engine you are replacing had catastrophic failure. This engine uses a Dynamic Fuel Management system, which is mechanically and electronically different from the previous L83 that uses Active Fuel Management. This means any cylinder can be considered for deactivation, not just the regular Cylinders 1, 7, 6, and 4 in the L83 and L86.
