What is the torque spec. for a 4.9L harmonic balancer pulley bolt?

Asked by kdm4smm Apr 20, 2012 at 02:44 PM about the 1993 Cadillac DeVille Sedan FWD

Question type: Maintenance & Repair

I have a 1993 Cadillac Deville 4 dr sedan with a 4.9L. I had to change the water pump. But it was also leaking behind the water pump. I had to remove the harmonic balancer pulley to fix this problem. Now all I need to get back running again is the torque spec for the crankshaft bolt. Thank you for your time.
