REPAIR (cont) - TM-5-4210-220-34_420
TM 5-4210-220-34 3-8. ENGINE Continued 3-8.4 Aftercooler - Continued REPAIR NOTE Aftercooler must be removed from truck; see REMOVAL preceding. A trace or crystal deposit left by evaporated coolant often indicates a potential leak or weak spot. If any trace of coolant or deposits are noticed, carry out step 11 following, prior to aftercooler cleaning. Aftercooler  repair  is  limited  to  the  replacement  of  seal  rings  in  the  grooves  of  the  water  inlet  and  water outlet tube ends. The only other repair is cleaning of the aftercooler which is governed largely by the kind of coolant and coolant additive used in the engine cooling system. (1) Check all of the cooler fins and air and water passages for plugging. Clean all obstructions from the fins using a small soft bristle brush. WARNING Death or serious injury could occur if compressed air is directed against the skin. Do not use compressed air for cleaning or drying unless the pressure is/has been reduced to 30 psi (2.11 kg/cm2) or less. When working  with  compressed   air   always   use   chip   guards,   eye   protection   and   other   personal   protective equipment. (2) Blow all excess dirt from aftercooler fins using compressed air. (3) Steam clean the outside of the core to remove any loose deposits. WARNING Dry cleaning solvent P-D-680 (safety or Stoddard’s solvent) is potentially dangerous. Avoid repeated and prolonged  breathing  of  vapors  and  skin  contact  with  the  liquid.  Do  not  use  near  open  flame,  arcing equipment or other ignition sources. Always wear eye protection and protective clothing. The flash point of P-D-680 is 100 to 138 deg. F (30 to 59 deg. C). (4) Use  dry  cleaning  solvent  (item  10,  Appendix  B),  clean  oil  and  dirt  from  the  aftercooler.  If  core  has  an excessive build up of dirt or carbon, allow aftercooler to soak in metal cleaner for about 12 hours. Leave the water  connections  open  so  that  the  cleaning  solution  can  penetrate  both  the  coolant  and  air  sides  of  the aftercooler. (5) Remove the core from the cleaning solution and rinse It thoroughly with a steam cleaner or high pressure hot water. (6) Blow out the air and water sides of the core using compressed air. To ensure that loose debris is not forced further into the fins, direct the stream of air opposite to the direction of normal coolant and air flow. (7) Rinse the core with clean dry cleaning solvent (item 10, Appendix B) to remove any residual oil or grease. (8) Rinse the solvent from the core using a steam cleaner or high pressure hot water rinse. 3-128
