When installing this pump onto the timing sprocket with the water pump holding tool of course ps thats sold on amazon too dirt cheap make sure to get the full moon one as to not drop bolts into your timing case it will prevent that while the half moon wont when installing this with the tool there is a 1 in 100ish chance the tool with have just enough slop in it that that ratcheting chain will move to the next tooth because its on the edge of the next one very not good

Everything will work fine but your car will have a supercharger noise when driving sign of a failed installation

Correction for this is to remove timing cover and removereset balance shaft chain tensioner to take excess tension off the chain due to the turned sprocket

You definitely do not want to your timing chain to fail and crash your engine

If you do decide to change only the water pump take your time and buy the special tool to hold the pump gear in place while you change the pump
