I did an internet search on this...you'll be taking a multitude of parts off to reach the buried h2o pumpy. Upper and lower intake, harmonic balancer,timing chain cover, which is thin and fragile, pluse time chains and associated components....there's more to remove...thus are just the high points.
I have no personal experience with this, nor do I want any.
Might be better for your stress level to just find the design engineer and administer a wood shampoo....
