Discovered this while replacing the fan bracket during a timing belt service.
The Service Manual on page 7-56 (p 263 of the PDF version, 2005) says:
2.8L DIESEL
(1) Assemble fan blade to viscous fan drive.
Tighten mounting bolts to 23.7 N·m (210 in. lbs.)
torque.
NOTE: The viscous fan and fan shroud must be
installed as an assembly.
(2) Gently lay fan and viscous drive into fan
shroud.
(3) Install the fan shroud to radiator mounting
bolt. Tighten bolts to 9 N·m (80 in. lbs.) torque..
(4) Thread the fan and viscous drive onto the fan
support and tighten nut using special tool 6958 spanner
wrench.
(5) Install cooling fan support to engine block (Fig.
38).
Torque bolts to 149 N·m.(110 ft. lbs.).(6) Install fan drive viscous clutch and fan assembly
(Refer to 7 - COOLING/ENGINE/FAN DRIVE
VISCOUS CLUTCH - INSTALLATION).
(7) Connect negative battery cable.
HOWEVER, page 7-19 (p226 of the PDF) has a table listing it at 35 ft-lbs.
.. about 2/3 of the way down the table:
Cooling Fan Support Bolts | 49N-m | 35 ft-lbs |It seemed pretty high (110) and when I felt the bolt stretch I went searching elsewhere and discovered it was supposed to be 35!
So, one trip down to the local (wonderfully stocked) hardware store to pick up two new bolts and all is well.
Glad I didn't leave half a bolt in the block, or strip the block threads!
Be careful -
