C. HEATER CORE HOSE
1) Remove the heater core hose from the water pump
(refer to the graphic on page 7). Cut off the last 4" of hose
at the water pump end. Set aside for now.
2) Cut off 2-1/2" of hose at the restrictor end.
3) Assemble the short end of the "Z" shaped aluminum
tube into the 2-1/2" hose on the restrictor with a #8
clamp.
4) Slide the 4" connector piece that was previously set
aside and the #8 clamps onto the long end of the
remaining single "L" curve aluminum tube. Slide the "L"
bend assembly onto the "Z" bend. Connect the hoses as
shown in the graphic on the next page.
5) Using the rubber "S" shaped coolant hose cut from the
original heater core hose and #8 clamps, connect the
single "L" curved aluminum tube to the water pump.
NOTE: For 1992 LT1 models, disregard the
following five points. There are no lower
