TM 3-4230-218-30&P MALFUNCTION TEST OR INSPECTION CORRECTIVE ACTION Step  3. Check   for   slipping   clutch. a. With  engine  running  at  a  constant  speed,  examine  water  pump drive   pulley   for   erratic   rotating   speeds. b. If  speeds  are  erratic,   clutch  is  slipping  and  is  defective. c. If   clutch   is   defective,   replace   clutch   (refer   to   page   2-33). d. If  clutch  is  not  defective,  proceed  to  step  4. Step  4. Check  for  defective  manometer  assembly. If  proper  unit  set  up  is  made  and  water  is  flowing  from  accessories but  no  pressure  is  indicated,   replace water manometer assembly (refer  to  page  2-71). 12.
