SOURCE: check engien lihgt with code p1762

CEL Code P1762 is Governor Pressure Sensor Offset Improper Voltage. Make sure all your wires going to the sensor are ok, then if they are I would look into a new Sensor. Hope this gives you some direction. Thanks for Using FixYa!

Sincerely,

JC

SOURCE: engine code 95 jeep grand cherokee lerado

12 is a battery disconnect within the last 50 start cycles and 55 means the end of the diagnostic cycle.  Basically the computer found nothing wrong. The 12 code may seem incorrect if you haven't disconnected the battery recently, but from my experience the 12 code shows up almost all the time regardless.

SOURCE: Changing the water pump on 2000 Jeep Grand Cherokee V6

WATER PUMP
The water pump is bolted directly to the engine timing chain case/cover.

A gasket is used as a seal between the water pump and timing chain case/cover.

If water pump is replaced because of bearing/shaft damage, or leaking shaft seal, the mechanical cooling fan assembly should also be inspected. Inspect for fatigue cracks, loose blades, or loose rivets that could have resulted from excessive vibration. Replace fan if any of these conditions are found. Also check condition of the thermal viscous fan drive. Refer to Viscous Fan Drive in this group.

The water pump can be removed without discharging the air conditioning system (if equipped)

REMOVAL
Disconnect negative battery cable from battery.
Drain cooling system. Refer to Draining Cooling System in this group.
Do not waste reusable coolant. If solution is clean, drain coolant into a clean container for reuse.

The thermal viscous fan drive is attached (threaded) to the water pump hub shaft. Remove fan/viscous fan drive assembly from water pump by turning mounting nut counterclockwise as viewed from front. Threads on viscous fan drive are RIGHT HAND. Using special tool spanner wrench 6958 with adapter pins 8346 and a suitable fan wrench loosen the fan drive Viscous Fan and Fan Drive Do not attempt to remove fan/viscous fan drive assembly from vehicle at this time.
WARNING: CONSTANT TENSION HOSE CLAMPS ARE USED ON MOST COOLING SYSTEM HOSES. WHEN REMOVING OR INSTALLING, USE ONLY TOOLS DESIGNED FOR SERVICING THIS TYPE OF CLAMP, SUCH AS SPECIAL CLAMP TOOL (NUMBER 6094) SNAP-ON CLAMP TOOL (NUMBER HPC-20) MAY BE USED FOR LARGER CLAMPS. ALWAYS WEAR SAFETY GLASSES WHEN SERVICING CONSTANT TENSION CLAMPS.

CAUTION: A number or letter is stamped into the tongue of constant tension clamps. If replacement is necessary, use only an original equipment clamp with matching number or letter.

If water pump is being replaced, do not unbolt fan blade assembly from thermal viscous fan drive.
Remove two fan shroud-to-radiator nuts Fan Shroud Mounting Hardware Do not attempt to remove fan shroud at this time.
Remove fan shroud and fan blade/viscous fan drive assembly from vehicle as a complete unit.
After removing fan blade/viscous fan drive assembly, do not place thermal viscous fan drive in horizontal position. If stored horizontally, silicone fluid in viscous fan drive could drain into its bearing assembly and contaminate lubricant.
Remove accessory drive belt as follows: The drive belt is equipped with a spring loaded automatic belt tensioner. Relax tension from belt by rotating tensioner clockwise (as viewed from front) Automatic Belt Tensioner - When all belt tension has been relaxed, remove accessory drive belt.
Remove lower radiator hose clamp and remove lower hose at water pump.
Remove seven water pump mounting bolts and one stud bolt
CAUTION: Do not pry water pump at timing chain case/cover. The machined surfaces may be damaged resulting in leaks.

Remove water pump and gasket. Discard gasket.
INSTALLATION
Clean gasket mating surfaces.
Using a new gasket, position water pump and install mounting bolts as shown. Water Pump Installation - Tighten water pump mounting bolts to 54 N·m (40 ft. lbs.) torque.
Spin water pump to be sure that pump impeller does not rub against timing chain case/cover.
Connect radiator lower hose to water pump.
Relax tension from belt tensioner Automatic Belt Tensioner - Install drive belt
CAUTION: When installing the serpentine accessory drive belt, belt must be routed correctly. If not, engine may overheat due to water pump rotating in wrong direction. Refer to Belt Routing for correct belt routing. Or, refer to the Belt Routing Label located in the engine compartment. The correct belt with correct length must be used.

Position fan shroud and fan blade/viscous fan drive assembly to vehicle as a complete unit.
Be sure the upper and lower portions of the fan shroud are firmly connected. All air must flow through the radiator.
Install two fan shroud-to-radiator nuts Fan Shroud Mounting Hardware
Be sure of at least 25 mm (1.0 inches) between tips of fan blades and fan shroud.
Install fan blade/viscous fan drive assembly to water pump shaft.
Fill cooling system. Refer to Refilling the Cooling System in this group.
Connect negative battery cable.
Start and warm the engine. Check for leaks

SOURCE: How to replace headlights on 2000 Jeep Grand Cherokee

One long bolt at the top - requires a 7mm socket to remove the bolt. The light housing will pry out with a screw driver. There are three ball and socket type connectors that hold the housing in and I just pryed off the plastic housing carefully and "balls" pop out of the sockets. Finally, I was replacing the faded plastic housing and it came with a new wiring harness. It's impossible to reach the connector to use the new wiring harness that comes with the new plastic light housing. So just use the existing wiring harness with the new light assembly.

If you have the same pulley arrangement that most 4.0 engines have that pulley is an idler not a tensioner. Your power steering pump has a pivot bolt, and a slide under the pump. You adjust belt tension using the pump.
