CAUTION:
q Always replace exhaust tube gaskets with new ones when reassembling.
q If the heat insulator is badly deformed, repair or replace it. If deposits such as mud pile up on the E
heat insulator, remove them.
q When installing the heat insulator avoid large gaps or interference between the heat insulator and
each exhaust pipe. F
q Remove deposits from the sealing surface of each connection. Connect them securely to avoid
gas leakage.
q Temporarily tighten mounting nuts on the exhaust manifold side and mounting bolts on the vehi- G
cle side. Check each part for unusual interference, and then tighten them to the specified torque.
q When installing each mounting rubber, avoid twisting or unusual extension in up/down and right/
left directions. H
