Inspection
At regular intervals, inspect the radiator mounting bolts for tightness. Inspect the isolators for deteriora-
tion or wear. Inspect the piping and hoses for deterioration or damage. Repair or replace any parts with
evidence of deterioration or damage. Check clamps and connectors for proper installation and tight-
ness. Examine the radiator core for leaks or damage to the fins. A damaged or clogged radiator should
be serviced by a radiator specialist or replaced with a new one. If the radiator core requires painting, use
special radiator paint (not an oil base paint, which prevents proper cooling). Drain and flush the entire
cooling system at the intervals recommended in the Preventive Maintenance chapter of this manual.
Removal
1. Drain the cooling system as described under “Draining the Cooling System” earlier in this chap
-
ter.
2. Disconnect all hose and piping connections to the radiator, including the breather line at the top.
Label each line for ease in reassembling the unit later.
3. Support the radiator from the bottom.
Remember that the radiator is very heavy.
Remove the
brace rods and mounting bolts.
4. Lower the radiator to clear the top of the door opening and rotate it sideways enough to fit
through the radiator access door. Using a suitable lifting device, the radiator may now be re-
moved through the radiator access door opening.
Installation
1. Use a suitable lifting device to lift the radiator and position it in place between the chassis outrig-
gers. The assembly must be turned to the side enough to fit through the access door.
2. Install the mounting bolts, isolators, and brace rods. Tighten the mounting bolts securely over
the vibration mounts. Vertical alignment is accomplished using the adjusting rods to position the
radiator correctly within the opening. Tighten the adjusting nuts on the brace rods to compress
the bushings used there.
3. Connect the previously tagged hose and pipe lines to the radiator. Loosely install the clamps.
4. Tighten the hose clamps on the inlet, outlet, and breather hoses.
5. If the surge tank was removed, install it on the mounting bracket with bolts at this time. Tighten
the bolts to 25–35 ft-lb (35–45 N-m) torque.
6. Fill the radiator and cooling system according to the procedure given in “Filling the Cooling Sys
-
tem” earlier in this chapter. Operate the engine and check the system for leaks. Check to ensure
the system was filled to the proper level.
