Part Comments
What came in the box? Were additional nuts, bolts, sealant, etc. needed for the repair?
If you are working on the 99+ Prizm, make sure you get the right valves. Geo made 2 sizes and rockauto only offers 1 size. I had the misfortune of finding this out. Napa ended up being able to special order the correct exhaust valve for me.
Repair / Installation tips:
Special tools needed? Have to remove other parts to reach this one? Any left-hand threads, sharp edges, messy fluids or other pitfalls to avoid?
