31 8 MOPAR PERFORMANCE PARTS7. Install the crankshaft pulley, the fan, and the radiator.Install the new 195 degree thermostat. This is critical.Temperature level of 195 degrees is critical for fuelsystem operation. Double check the thermostat andmake sure that it is installed in the housing correctly.Make sure that the thermostat itself does not dropdown when installing the housing onto the engine. Ifthat happens, the housing will leak. Just a smallamount of heavy grease will hold the thermostat inplace while you install the housing. Install the coolantsensor supplied into the new thermostat housing in the3/8“ pipe hole, then reinstall this new assembly on theengine. When installing radiator and heater hoses,reroute the new heater hose supplied, as it no longergoes through the intake manifold.Figure 5 - 158.9.Note: On some serpentine belt engines, the CoolantTemperature Sensor will not fit in the thermostathousing. The idler pulley bracket is too close. If youhave this problem, you can install a 3/8“ pipe plug inthe thermostat housing and relocate the temp sensorinto the heater hose. You will need to splice an adapterinto the heater hose. The adapter is a “4 Seasons” partnumber 84540, should be available at your localhardware store or air conditioning supplier, or perhapsat your local auto parts store.Install the new intake manifold. You will only be ableto reinstall one of the power steering pump bracketbolts and you may have to trim the top lip off of thepower steering pump bracket to make it fit the newmanifold. With the new intake manifold, this bracketdoes not actually bolt to the manifold itself. Thebracket does not need to be bolted to the manifold andwill not cause any power steering pump mountingproblems. For a cleaner look to the engine, you mightwant to modify the bracket a little more beforeinstalling it to the back of the power steering pump.Just cut the bracket horizontally above the powersteering pump top bolt hole. This will eliminate theportion of the bracket that bolts to the intake manifold.DO NOT over tighten the intake manifold bolts! Bolttorque is 23 ft-lb (Figure 5-15). Take your timeinstalling these bolts. Make sure that all the intakemanifold cup washers are seated properly.Install the throttle cable and bracket (Figure 5- 16 andFigure 5-17).Figure 5 - 16
