WARNING: The normal operating temperature of the exhaust system is very high. Never work around or attempt to service any part of the exhaust system until it is cool. Care should be taken when working near the turbocharger. The temperature of the turbocharger rises to a high level after a short period of engine operation time.
NOTE: There is no procedure for repairing the turbocharger. If damage is found during inspection, the turbocharger must be replaced.
