A high concentration of caustic cleanercan attack the internal metals of the core and causeleakage. Only use the recommended concentration flush the core with recommends the use of hot Hydrosolv100 liquid cleaner at a concentration of 30% andat a temperature of 66 to 82 C (150 to 180 F).

Rinse thecore thoroughly with clean injury can result from air injury can result without following prop-er procedure. When using pressure air, wear a pro-tective face shield and protective air pressure at the nozzle must be lessthan 205 kPa (30 psi) for cleaning the core with compressed air.

Impellers have a servicelife that is limited. The service life depends on theengine operating the components of the pump morefrequently when the pump is exposed to debris,sand, or other abrasive materials. Inspect thecomponents if the pump is operating at a differentialpressure of more than 103 kPa (15 psi).Check the following components for wear andcheck the following components for damage: Cam Impeller Seals Wear plateIf wear is found or if damage is found, replacethe components which are worn or replace thecomponents which are damaged.

10 Replace belts thatare worn or applications that require multiple drive belts,replace the belts in matched sets. Replacing onlyone belt of a matched set will cause the new belt tocarry more load because the older belt is additional load on the new belt could cause thenew belt to the belts are too loose, vibration causesunnecessary wear on the belts and pulleys. Loosebelts may slip enough to cause the belts are too tight, unnecessary stresses areplaced on the pulley bearings and on the belts. Thismay shorten the service life of the the belt guard. Inspect the condition andadjustment of the alternator belts and accessorydrive belts (if equipped).64 Maintenance SectionCooling System Coolant (DEAC) - ChangeTo check the belt tension, apply 110 N (25 lb ft)of force midway between the pulleys.
