Found a little bit of thin scrap metal on the casting that needed a file to remove to restore full opening of one of the ports. On tip I wish I had been told - Before putting the new water pump on the engine check the threads in the pump flange bolt holes. Run the 6mm Allen head flange bolts in and out of the pump flange threaded holes and verify the bolts engage and thread in easily with the pump on the bench. I had a ton of trouble getting these bolts to engage and then when they did engage they wanted to cross thread. 3 out of 4 gave me difficulty getting started and one felt cross threaded all the way in. The bolts were factory bolts and threads looked fine. Have a feeling this job would have been much easier if I had threaded a bolt or maybe even a tap into each bolt hole first. As I paid no attention to the bolt holes and only tried them after pump was installed can’t really confirm if there was an issue with the pump threads or if this is operator error, but it would have been an easy check before contorting that pump in there. Each of the 4 flange bolts posses its own unique access challenge once the pump is on the motor. Van is running great with the new pump, glad to have it on there, hope it last many miles to come!
