Answered my own question with a YouTube video. I am waiting on parts to do the coolant flange. While I have the coolant drained I’m going to give the timing belt and water pump a shot. And also the cam follower. I’m going to just take off the vacuum pump to access the flange. It seems that just the heater hose port of the flange is leaking so I’m going to replace the heater hoses too. Any tips would be appreciated.
