ISC/L - Rear Radiator e/w Fan Clutch - engine over heats, fan clutch operation is opposite what it should be.

 Finally in April, 2007 FCCC made the fan clutch standard equipment on all rear radiator chassis. However, on some of the early rear radiator chassis with Cummins engines, the fan clutch wiring did not match Cummins firmware in their ECM. This made the fan clutch operation 'backwards' leading to overheating on some of these chassis, i.e. when the engine heated up, the ECM would turn the fan clutch OFF instead of ON. This Service Campaign aligns the wiring with the ECM firmware so the fan clutch operates the fan when engine temps indicate more cooling is needed. When additional cooling is not needed the fan clutch operates in an idle mode, thus saving HP and therefore increasing MPG.

Since FCCC does not furnish us with copies of Service Campaigns, we don't know the start/end dates nor the number of units involved. If you have a copy of this Service Campaign, please send us a copy (see email above).

Muffler Bracket Clamp - XC, CAT C7, Rear Radiator

This campaign was EXTENDED till April 30, 2008 and is now expired.

"Freightliner Custom XC and XC-S chassis manufactured between Sept. 22, 2003 and Nov. 29, 2005 with CAT C7 engines and rear radiators."

"A change in the supplier of the clamps used on the left hand exhaust pipe assemblies resulted in clamps with a different clamping load, this may allow the assembly to loosen."

"Retaining screws will be installed thru the clamp, exhaust tube and muffler bracket."

Editors note: Several experienced owners who had this fix applied were NOT happy with FCCC's fix which involved adding 3 sheet metal screws thru the muffler adapter to the exhaust pipe and muffler.  Their concern was the use of non stainless steel screws which are subject to rust corrosion and loosening due to vibration.  They would have preferred that FCCC replace the clamp assembly with a clamp of appropriate size. 

Here is a picture of one fix from a FTL dealer -

Fixes after this date will be at owners expense.

ISL - Side Radiator Thermal Dynamic Hydraulic oil coolers

Specific Freightliner Custom XC motorhome chassis with [Cummins ISL engines and] side mounted radiators manufactured between Sept. 24, 2003 and January 1, 2006 with certain Thermal Dynamic hydraulic coolers.  The oil coolers on some vehicles using 15W40 motor oil in the hydraulic system may crack due to over pressurization.  [Note - this campaign does not apply to CAT engines with side mounted radiators, only certain chassis with ISL engines.]

The oil cooler will be replaced with a cooler that has a higher flow rate and pressure rating.

The Field Service Campaign will terminate on June 30, 2007.

Editors Note - This Campaign is related to the SB 20-10 below for certain chassis which changed the hydraulic oil with 15W40 motor oil to help with ISL engine overheating.  Certain chassis had some oil coolers that might not handle the increased pressure using motor oil instead of the original hydraulic fluid.  Owners that were involved in the Service Campaign reported that if their fluid had not been changed earlier from hydraulic fluid to motor oil, it was changed on this campaign when the new cooler was installed.  The reason the fluid was changed was to increase the thermal handling capabilities for the side mounted radiator variable speed motor. The motor oil has a wider temperature range than the hydraulic fluid.  Those chassis that had the fluid changed also had a new label affixed to the hydraulic fluid container...the new label says Motor Oil.  Not all ISL side mounted radiator equipped chassis had this problem, only certain chassis indicated in the date ranges.

Side Radiator overheating - Cummins ISL-400 applications

This service bulletin concerns an overheating problem with FCCC
XC and XCR chassis with the 400 hp Cummins engine with side radiator
manufactured between October 4, 2004 and April 28, 2005.  Installation
details include a rock guard under the radiator, hydraulic fluid change
to engine oil, rear cap insulation, and a new grill.

Improved Info Center Backlighting

FTL chassis built between 8/29/2003 and 6/5/05 were equipped with the Info Center using the green/black display that is hard to read. The Info Center is connected to the ECM to display certain engine performance data. A new improved model is available from the supplier at a discount...see details below.

Brake Lights quit working on coach

If your '98 or '99 coach has it's brake lights go out, here is info on the two diode wiring harness (replacement for the single version).

Battery Drain/Headlight Relay Fix

"Battery drain may occur if the headlights are left in the high-beam position when the engine is shut down.  This does not affect the operation of the headlights in either high- or low-beam position, but can drain the chassis batteries in four to five days if the vehicle is not operated.

The Signal source for the Hi/Lo dimmer control of the headlight relay needs to change from battery power (circuit 24) to ignition power (circuit 74) in the cab harness.  This will eliminate battery drain, if the dimmer relay is left closed.

Since June 1999, a new harness has been installed in vehicles.  There is no field action necessary for VCL models as none had been build as of the changeover date.

XC chassis build with System III multiplex wiring (pre-series units built May 1998 and production units build since January 1999) need to have the wiring modification.
