Q: How to replace the water pump pulley on Cadillac DTS?
A: You need to free the outer water pump Drive Belt tensioner before taking off its Drive Belt and Water Pump Pulley. You can remove the end cap from the intake Camshaft with ease before utilizing the power steering and Water Pump Pulley remover (J 38825) to detach the water pump drive pulley from the intake Camshaft. Put the water pump drive pulley on the intake Camshaft then snap it into place using the Water Pump Pulley installer j 38823 until it hits the Camshaft at the right depth as indicated by the tool's lower edge. Install the Camshaft end cap and fasten it at 2 n.m (18 lb in). Then put the water pump Drive Belt into position.
