well I have just completed the task of changing out the water pump, timing chains, and plugs, coil packs. figured I am in it this far.
The 2 parts that were the hardest was to remove the top bolt on the power steering pump and pulling out the front plate.
I went and purchased the steel plates that lock up the valve timing. money well worth spending, never have to worry about anything moving while you replace all 3 timing chains. I replaced all valve cover gaskets as well as the intake gaskets, the car is 2008 with 350000+ km on the car.
Make sure you clean both sides of the front plate as this only gets a thin film of silicone, and this is not your ordinary silicone. make sure you use the correct one that states for engines and is oil resistant.
Took about 20-25 hours for myself to do it.
You will need to get a harmonic balance puller, harmonic balance installer. I did not want to hammer the harmonic balance back on.
I also went through 4 cans of break cleaner to get rid of all the oil/fumes off the parts. found the oil pan has some dead spots where there is lots of gunk sitting in the corners.
There is a great video you can watch, its a two part. This is for the Ford Flex but its the same engine,
