I think the heater hoses are 3/4 and 5/8 but , which ones go where? Tightening the hose clamps is an adventure any suggestions on a easier way? graemlins/clonk.gif

The 3/4" hose goes from the water pump to the top heater core nipple, and the 5/8" hose goes from the intake manifold nipple to the lower nipple on the heater core. graemlins/thumbsup.gif
