As it goes, now the coolant system refresh is now. It has a coolant leak as of yesterday. I'm ordering a few more parts to tear it apart next week.
Attached is a DISA valve repair kit. It's aluminum. Looks okay. Where do the small washers go?
The Rein kit was checked. All the hoses are made in Germany except for one. The block straight pipe says China but still in a Rein package.

Should I replace it with a different brand?
Is there anything else I should replace while the intake is off?
