Great ride, dependable and performs well with that engine.The 5.7L engine (345 CID) eight-cylinder engine is a 90° V-Type lightweight, deep skirt cast iron block, aluminum heads, single cam, overhead valve engine with hydraulic roller tappets. The heads incorporate splayed valves with a hemispherical style combustion chamber and dual spark plugs.
The Multiple Displacement System (MDS) provides cylinder deactivation during steady-speed, low-acceleration and shallow grade climbing conditions to increase fuel economy.
MDS can provide a 5-20 percent fuel economy benefit when operating in four-cylinder mode, depending on driving habits and vehicle usage. For EPA rating purposes, fuel economy is 8-15 percent higher than if the engine was operating on eight cylinders at all times.
MDS is integrated into the basic engine architecture, requiring a minimum of additional parts - four additional solenoids, an oil temperature sensor and a wire harness. Eight unique valve lifters and a modified camshaft are also required.
Power steering systems consist of:
- Steering column AND Intermediate Shaft
- Rack and pinion steering gear
- Belt driven hydraulic steering pump
- Pump pressure, supply and return hoses
- Oil Cooler
- Hydraulic cooling fan
The 545RFE automatic transmissions is a sophisticated, multi-range, electronically controlled transmission which combines optimized gear ratios for responsive performance, state of the art efficiency features and low NVH. Other features include driver adaptive shifting and three planetary gear sets to provide wide ratio capability with precise ratio steps for optimum driveability. The three planetary gear sets also make available a unique alternate second gear ratio. The primary 2nd gear ratio fits between 1st and 3rd gears for normal through-gear accelerations. The alternate second gear ratio (2 prime) allows smoother 4-2 kickdowns at high speeds to provide 2nd gear passing performance over a wider highway cruising range.
The 545RFE gear ratios are:
1st-3.00:1
2nd-1.67:1
2nd Prime-1.50:1
3rd-1.00:1
4th-0.75:1
5th-0.67:1
Reverse-3.00:1
If it's a 4WD,
The NV245 transfer case provides Full-Time Active Four-Wheel Drive for optimum traction in a wide range of conditions and is used in Quadra-Trac® II and Quadra-Drive® II systems. The transfer case center differential distributes torque 48 percent to the front axle and 52 percent to the rear axle along with an electronically controlled clutch pack that is coupled to the center differential for torque biasing. The NV245 electronics provide an active system because it can anticipate and prevent slip. The transfer case can redistribute 100 percent of torque to the front or rear axle, depending on need. For added traction when traversing steep grades, rough terrain or extremely slippery/poor traction surfaces at low speeds, the transfer case can be switched into 4WD Low, which multiplies engine torque 2.72 times and locks the clutch pack for maximum traction at all times. The Neutral mode allows the vehicle to be flat towed behind another vehicle.
Electric shifting is accomplished with a T-handle transfer case lever in the shifter assembly to provide simplified operation and positive engagement of 4 Low. A pushpin button is provided to shifting the transfer case into NEUTRAL.
This vehicle uses the Continental Teves MK25e electronic brake control system. The system includes ABS (Anti-lock Brake System), EVBP (Electronic Variable Brake Proportioning), TCS (Traction Control System), BAS (Brake Assist System), ERM (Electronic Roll Mitigation) and ESP (Electronic Stability Program). All six systems work together to enhance vehicle stability and control in various driving conditions and are commonly referred to as ESP. ESP is standard
The electronic brake control system uses the following components to operate:
- Integrated Control Unit (ICU) – The ICU is a combination of the Electronic Brake Controller (EBC) and the Hydraulic Control Unit (HCU) (4)
- Wheel Speed Sensors (WSS) - Four sensors (one at each wheel)
- Dynamics Sensor – The Dynamics Sensor includes a yaw rate sensor, (The Dynamics Sensor is located under the center console near the center of the vehicle).
- lateral accelerometer and, on 4x4 vehicles with a low range transfer case (245 T-Case), a longitudinal accelerometer.
- Steering Angle Sensor (SAS) – The SAS is part of the clock spring assembly in the steering column.
- Brake Pressure Sensor – The brake pressure sensor is located in the HCU and is not serviceable separate from the HCU.
The TCS is an all-speed traction control system that functions up to the maximum allowed vehicle speed. TCS enhances vehicle stability and mobility by reducing wheel spin when accelerating on slippery surfaces. TCS controls wheel spin by applying the brakes and/or reducing engine power.
The BAS is designed to optimize the vehicle’s braking capability during emergency braking maneuvers. The system detects an emergency braking situation by sensing the rate and amount of brake application and then applies optimum pressure to the brakes. This can help reduce braking distances. The BAS complements the antilock brake system (ABS). Applying the brakes very quickly results in the best BAS assistance.
The ESP system enhances directional control and stability of the vehicle under various driving conditions. ESP corrects for over/under steering of the vehicle by applying the brake of the appropriate wheel to assist in counteracting the over/under steer condition. Engine power may also be reduced to help the vehicle maintain the desired path. ESP uses sensors in the vehicle to determine the vehicle path intended by the driver and compares it to the actual path of the vehicle. When the actual path does not match the intended path, ESP applies the brake of the appropriate wheel to assist in counteracting the oversteer or understeer condition
- Oversteer – when the vehicle is turning more than appropriate for the steering wheel position.
- Understeer – when the vehicle is turning less than appropriate for the steering wheel position.
The “ESP/TCS Indicator Light†located in the instrument cluster, starts to flash as soon as the tires lose traction and the ESP system becomes active. The “ESP/TCS Indicator Light†also flashes when TCS is active.
ERM,
This system anticipates the potential for wheel lift by monitoring the driver’s steering wheel input and the speed of the vehicle. When ERM determines that the rate of change of the steering wheel angle and vehicles speed are sufficient to potentially cause wheel lift, it applies the appropriate brake and may reduce engine power to lessen the chance that wheel lift will occur. ERM will only intervene during very severe or evasive driving maneuvers.
ERM can only reduce the chance of wheel lift occurring during severe or evasive driving maneuvers. It can not prevent wheel lift due to other factors such as road conditions, leaving the roadway or striking objects or other vehicles.
As for the price, It's reasonable depending on how loaded it is. Make sure you check it's service history if available and do your own homework checking it yourself. See if there's any signs of any prior body damage.
