ALIGNING THE SECTIONS
Carefully slide the second section next to the first so that the nipples
align with the connections correctly.
CONNECTING THE SECTIONS
Mark how far to insert the nipple key by placing it over the top of
the radiator so that the end aligns with the nipples to be turned.
Slide the key in from the open end of the waterway until it engages
into the nipple that needs tightening. Keep the key as parallel to the
floor as possible for easier insertion; forcing the key will jam it in the
waterway. Once the key is inserted enough, check the end of the key
has fully engaged in the internal lugs inside the nipple.
One turn at a time, rotate the nipple using the nipple key. This will
pull the two sections together. After one turn, repeat with the other
nipple. Continue to alternate between the nipples, one turn at a time,
until the two sections are pulled together. It is important to keep the
sections parallel to one another.
When the sections are connected, tighten the joints so the gaskets are
firmly compressed. A tightening torque of 100 lbf-ft must be applied.
Do not test with air.
