3.6.8. EGR cooler
1) Introduction
z EGR cooler is heat exchanging device that reduces the temperature of
recirculating exhaust gas.
z EGR cooler enhances fuel efficiency while reducing the amount of NOx
generation.
2) Feature
z High efficient tube & fin type applied.
3.6.9. EGR system installation and disassembly
1) Disassembly
(1) Disassemble the EGR valve (K) and elbow pipe (L)
(The above should be performed when heat screen (O) and bellows pipe (N)
are previously disassembled.)
: EGR system should be cooled after long hours of operation before initiating
disassembly.
z Disassemble nut (P) from stud bolt (M).
z Cooling pipe should be disassembled when disassembling EGR valve.
(2) Disassembling EGR Bracket should be performed after disassembling
exhaust manifold (A)Part.
2) Installation
Installation process should be preformed in reverse order of disassembly.
3.6.10. EGR cooler installation and disassembly
1) Disassembly
EGR system should be cooled after long hours of operation before initiating
disassembly.
(1) Please take apart water inlet, outlet pipe and hose.
(2) Please take apart gas outlet pipe and hose.
(3) Please take apart heat screen.
(4) Please disassemble (N) part
(5) Please disassemble EGR cooler assembly bolt.
(6) Please EGR cooler from EGR bracket.
2) Installation
