Repair 7

The water pump in the 1998 Ford Explorer is located on the front of the engine block by the cooling fan. It circulates coolant through the block to prevent the engine from overheating during its operation. The primary symptom of a faulty water pump is a continually increasing engine temperature, even with the proper amount of coolant. A malfunctioning water pump causes excessive wear to the engine and may eventually damage the engine permanently.

Instructions

1

Disconnect the batterys negative terminal with a socket wrench. Position a drain pan under the radiator and open the radiator drain. Replace the plug after the coolant is completely drained from the radiator.

2

Disconnect the cooling fan shroud with a socket wrench. Remove the mounting bolts for the cooling fan. Remove the cooling fan assembly. Disconnect the accessory drive belt.

3

Detach the water bypass hose and heater hose from the water pump. Disconnect the brackets for the wiring harness of the engine control sensor, and push the wiring harness out of the way. Remove the attaching bolts for the water pump pulley with a socket wrench and disconnect the pulley.

4

Remove the attaching bolts for the water pump. Record the position of each bolt since they have different lengths. Detach the pump from the front engine cover. Disconnect the radiator hose from the water pump. Remove the pump from the vehicle and discard its gasket.

5

Clean the mounting surfaces of the pump and front engine cover with a shop towel. Apply a layer of gasket sealer to both sides of the new gasket. Mount the gasket onto the water pump.

6

Connect the radiator hose to the new pump. Install the pump and place the mounting bolts in the correct holes that you recorded earlier. Torque the mounting bolts to between 15 and 21 foot-pounds with a torque wrench. Complete the installation of the water pump by performing steps two and three in reverse order.

7

Refill the cooling system with coolant and reattach the negative battery cable with a socket wrench. Start the engine and check for leaks in the cooling system.

There may be many reasons to replace a wiper arm on a 1998 Dodge Dakota Sport. Having to replace an entire arm is a rare repair. Having to replace the wiper blade is much more common. However, if a wiper arm becomes damaged, bent or the splined cog of the pivot hole gets stripped (most often caused by wipers being turned on when stuck frozen to ice or snow), the wiper arm will need replacement. While replacing wiper arms is pretty standardized among many makes and models, there are a few subtle differences in the Dodge Dakota.

Instructions

1

Turn the windshield wiper motor to the Off position. If a wiper arm is misaligned, it will not matter at this time.

2

Open the hood to the Dodge Dakota Sport. The pivots at the base of the wiper arms on the Dakota are slightly concealed by the hood when in the closed position.

3

Lift the pivot cover upward from the base of the wiper arm to reveal the wiper arm retaining nut.

4

Remove the retaining nut with a ratchet and 15mm socket by turning it counterclockwise.

5

Pry the wiper arm (caully, but firmly) upward off the pivot stud using the wiper arm removal tool. Move the position of the tool around the base of the blade near the pivot to work the arm off evenly.

6

Remove the wiper blade from the removed wiper arm (if reusing). If not, place the replacement wiper blade onto the new wiper arm before installing it.

7

Place the new wiper arm onto the pivot so the wiper arm is placed in its down/off location. Do not turn the arm to align it once on the splined pivot. If necessary, remove the wiper arm and align it properly.

8

Replace the retaining nut and tighten.

9

Reposition pivot cover and snap it into place.

10

Repeat the same procedure for the opposite wiper arm before closing the hood and testing the new wiper arms.

The 1998 Suzuki Esteem was an economical compact car---available as a sedan or a wagon---offering reasonable space and practicality. The Esteem had an understated generic design, but it offered a solid 1.6L, in-line, 4-cylinder engine capable of delivering 95 horsepower. With its light 2,250-pound curb weight, the Esteem posted very respectable fuel economy figures of 37 miles per gallon on the highway and 30 miles per gallon in the city.

Fuel Pump

The Esteems electronically controlled fuel pump is located in the gas tank. As its name suggests, its function is to pump gas through the fuel lines to the engine compartment.

Fuel Pressure Regulator

The fuel pressure regulator, located under the hood, is responsible for feeding fuel directly to the injectors at the correct pressure. This is controlled by the electronic control unit---or ECU---and is based on several parameters, including driver throttle input and revolutions per minute. The regulator must be in good working order, as failing to feed fuel into the engine at the correct pressure can cause severe issues, such as back-firing or even detonation caused by the improper ratio of air to fuel.

Fuel Injectors

The Esteem is equipped with four small fuel injectors, each responsible for providing fuel to the combustion chamber. The injectors are also controlled by the ECU, which instructs the injectors when and for how long to release fuel. Injectors must be free from deposits or contaminants to operate effectively.

Fuel Filter

The fuel filter screens out any foreign object or debris that may accumulate in the fuel tank.

Audi created the radio in a 1998 A4 with security in mind. The radio has a built in anti-theft system that locks out the radio functions whenever it loses battery power.

The EGR valve of a Chrysler Sebring regulates the flow of air from the exhaust to the intake system in order to control the air temperature and the amount of nitrogen. A faulty EGR valve will result in poor combustion and engine knock, causing the car to rattle or misfire. Because they are calibrated together, the EGR valve and transducer are sold together and must be installed as a set. While the 1998 Sebring has two different locations for the EGR valve, depending on the type of engine, replacing it is a DIY job that will dramatically improve vehicle performance.

Instructions

1

Raise the car hood and disconnect the negative battery terminal. If your 1998 Sebring has a 2.0- or 2.4-liter engine, the EGR valve is located behind the cylinder head, so remove the large tube connecting the air intake to the air filter for added clearance. On the 2.5-liter engine, the EGR valve is to the left of the positive battery terminal, so remove the transmission control module (TCM) for clearance. The TCM is located to the left of the engine fuse box, and the positive battery terminal is secured by a central retainer and retaining screws.

2

Remove the vacuum tubes and electrical connections from both the EGR valve and electrical transducer, including the line to the solenoid, making sure to label where each tube goes for reinstallation. Remove the metal EGR tube leading to the intake manifold and clean its mounting surface. Unfasten the bolts holding the EGR valve and transducer. Carefully remove each component.

3

Loosely connect the EGR tube with the new EGR valve, using new gaskets. Install the new EGR valve and transducer. Once the components are in place, tighten the screws on the EGR tube and any remaining loose bolts. Reconnect all of the vacuum tubes connecting the EGR valve, transducer and solenoid as labeled.

4

Reinstall any components that you removed for access and reconnect the negative battery terminal. Start the engine and carefully listen for a hissing sound that would indicate a vacuum leak. Correct any vacuum leaks, if necessary, using a small amount of gasket-making compound to seal connections.
