DODGE RAM SRT-10 2006 Service Repair Manual

HEAT SHIELDS
DESCRIPTION
There are two types of heat shields used. One is stamped steel the other is molded foil sheets. The shields attach
to the vehicle around the exhaust system to prevent heat from the exhaust system from entering the passenger
area and other areas where the heat can cause damage to other components.

2. Remove the nuts or bolts holding the exhaust heat
shield to the floor pan, crossmember or bracket.

3. Slide the shield out around the exhaust system.
INSTALLATION

TURBOCHARGER SYSTEM
DIAGNOSIS AND TESTING
TURBOCHARGER BOOST PRESSURE
Low turbocharger boost pressure can cause poor engine performance and driveability concerns. The following pro-
cedure will test the turbocharger boost pressure.
Causes of low boost pressure include the following:
Restricted air inlet system
Leak in charge air cooler system
Restricted/high pressure drop across charge air cooler
Damaged turbocharger compressor wheel housing
Turbocharger wastegate stuck open
Excessive exhaust restriction
Causes of excessively high boost pressure include:
Turbocharger wastegate stuck closed
Turbocharger wastegate signal line leaking or damaged
Damaged wastegate command valve O-rings
Wastegate command valve mechanically stuck in actuated position
Several Diagnostic Trouble Codes (DTCs) can be set that will indicate highor low system boost levels. There is a
DTC for circuit faults relating to the electronically controlled wastegate command valve.
(Refer to 11 - EXHAUST SYSTEM/TURBOCHARGER SYSTEM/CHARGE AIR COOLER AND PLUMBING - DIAG-
NOSIS AND TESTING) for diagnosing of low or high boost pressure due to leaks.
NOTE: If oil is present on either the inlet or exhaust side of the turbo charger, check the charge air cooler
for evidence of oil. Clean charge air cooler of any oil before starting the engine. Failure to do this can result
in severe engine damage.
