Installation Notes

Verify flange diameter, outlet diameter, and bolt-hole layout before installation. Clean the mating surfaces thoroughly, inspect the coolant passages for corrosion or debris, and confirm the cooling system is filled and bled according to factory procedure. The jiggle pin helps with air evacuation during service, but proper bleeding is still important for stable temperature control.
