Jeep Rattle And Clatter

1) Heater core supply and return hoses. 2) Purge solenoid. 3) Purge solenoid wire harness.
This bulletin applies to 2011-2012 Jeep Compass and Patriot vehicles equipped with a 2.4L engine and either the continuously variable transaxle or the continuously variable transaxle with off-road crawl ratio that exhibit a rattle and/or clatter sound during cold startup. The fix involves installing revised heater hoses, routing the purge solenoid wire harness and installing revised PCM software.
-
Replace the transmission shifter cable.
-
Remove the right wheel inner splash shield.
-
Position a clean collecting container under the draincock location.
-
Without removing the pressure cap and with the system not under pressure, turn the draincock counterclockwise to open.
-
The coolant reserve bottle should empty first. Then remove the pressure cap.
-
Allow the cooling system to drain completely.
-
Remove both supply and return heater core hoses.
-
Install new heater core supply hose P/N 05058822AB and heater core return hose P/N 05058823AB.
-
Install the right wheel inner splash shield.
-
Remove the engine cover.
-
To ensure that the purge solenoid wiring harness does not come into contact with the heater hoses, the wire harness will require a slight modification.
-
Loosely pull the purge solenoid wire harness straight and create a bend in the harness approximately 3/8-7/16 inch away from the harness retaining clip edge. This bend will also create a natural bend after the current spot tape on the harness. The apply 3-4 wraps of electrical tape, securing the bend to the harness.
-
Install the engine cover.
-
Fill the cooling system making sure that no air is trapped in the engine.
-
Reprogram the PCM with the latest software.
-
After PCM reprogramming, clear any DTCs.
