Did you try to tighten the hose clamp? The thermostat housing bolts have proper torque?This info is for 3.4L cx engine.
Remove the air cleaner and duct assembly.
Drain coolant until coolant is below the thermostat.
Remove the crossover exhaust pipe.
Remove radiator hose from thermostat housing.
Remove the thermostat housing bolts and so on.
