1999 DODGE RAM water pump

CAUTION: After removing fan clutch assembly, DO NOT store fan clutch
with rear of shaft pointing downward. Silicone fluid from fan
clutch may drain into fan drive bearing, causing lubricant
failure.
Removal
1) Disconnect negative battery cable. Drain cooling system.
Remove throttle cable at top of fan shroud. Unsnap coolant overflow
tank from fan shroud and lay aside. DO NOT disconnect coolant hose.
2) Remove upper radiator hose. Using Fan Wrench (SP346) from\
Set (2017DSP), remove fan clutch assembly from water pump by turning
nut counterclockwise as viewed from front. DO NOT remove fan clutch
assembly at this time.
3) Remove fan shroud bolts and clips. Remove fan shroud and
fan clutch assembly as a unit. Locate accessory drive belt tensioner,
and rotate tensioner clockwise (counterclockwise on heavy-duty cycle
engines) to release tension on accessory drive belt.
4) Note drive belt routing for installation reference. Belt
must be correctly routed during installation, or engine will overheat
due to water pump rotating in wrong direction.
5) Remove bolts and water pump pulley. Disconnect lower
radiator hose and heater hoses. Remove coolant return tube from water
pump. Remove bolts, water pump and gasket.
Installation
To install, reverse removal procedure using NEW gasket.
Tighten bolts to specification. See TORQUE SPECIFICATIONS table. Fill
system with coolant. Ensure accessory drive belt is installed in
original direction to ensure proper rotation of water pump. See
Fig. 12 .

INTRODUCTION TO MOTORIST ASSURANCE PROGRAM (MAP)
OVERVIEW OF MOTORIST ASSURANCE PROGRAM
The Motorist Assurance Program is the consumer outreach
effort of the Automotive Maintenance and Repair Association, Inc.
(AMRA). Participation in the Motorist Assurance Program is drawn from
retailers, suppliers, independent repair facilities, vehicle
manufacturers and industry associations.
Our organization's mission is to strengthen the relationship
between the consumer and the auto repair industry. We produce
materials that give motorists the information and encouragement to
take greater responsibility for their vehicles-through proper,
manufacturer-recommended, maintenance. We encourage participating
service and repair shops (including franchisees and dealers) to adopt
(1) a Pledge of Assurance to their Customers and (2) the Motorist
Assurance Program Standards of Service. All participating service
providers have agreed to subscribe to this Pledge and to adhere to the
promulgated Standards of Service demonstrating to their customers that
they are serious about customer satisfaction.
These Standards of Service require that an inspection of the
vehicle's (problem) system be made and the results communicated to the\
customer according to industry standards. Given that the industry did
not have such standards, the Motorist Assurance Program successfully
promulgated industry inspection communication standards in 1994-95 for
the following systems: Exhaust, Brakes, ABS, Steering and Suspension,
Engine Maintenance and Performance, HVAC, and Electrical Systems.
Further, revisions to all of these inspection communication standards
are continually re-published. In addition to these, standards for
Drive Train and Transmissions have recently been promulgated.
Participating shops utilize these Uniform Inspection & Communication

Reasons to Suggest Repair or Replacement
1 - Part is close to the end of its useful life (just above
discard specifications, or weak; failure likely to occur
soon, etc.)
2 - To address a customer need, convenience, or request (to
stiffen ride, enhance performance, eliminate noise,
etc.)
3 - To comply with maintenance recommended by the vehicle's
Original Equipment Manufacturer (OEM)
4 - Technician's recommendation based on substantial and
informed experience
NOTE: Suggested services are always optional. When presenting
suggested repairs to the customer, you must present the
facts, allowing the customer to draw their own conclusions
and make an informed decision about how to proceed.
