Great system with some flaws

After installing the kit I learned a few things. There is no way to see the timing pointer or balancer to set timing for the engine. I removed the power steering pump and still could not see to set timing. A view is available from behind the water pump, but it is not any help due to the angle. Also had to remove the passenger side valve cover to install the second bolt for the A/C compressor. So make sure your timing is set before installing. Otherwise the product works great.
