WaterPumps Fitting guide

This guide is intended to provide you with a basic understanding of how to replace a conventional water pump on a common vehicle; not to provide in-depth knowledge of cooling systems. This guide will not cover timing belt driven water pumps which are typically beyond the scope of do-it-yourselfers. It will assume that you are familiar with the basic components of a cooling system such as the water pump, radiator, thermostat, coolant, et cetera. It may be necessary to lift the front of the vehicle in order to complete the repair. Part of the procedure requires the engine to be running at operating temperature. Use extreme caution when working around hot engine components and keep all loose clothing, jewelry, hair, et cetera, away from moving engine parts. Use extreme caution to ensure your car or truck is properly supported at all times.

Water Pump Problems

Defective conventional water pumps are probably one of the easiest problems to diagnose. They will either spring a leak or the bearings that support the impeller shaft will wear out and rattle. To determine whether your water pump is leaking, simply inspect the water pump gasket from where the water pump mates with the engine block or timing cover. In some cases, the leak may not be fresh and you may see a powdery white residue. These spots will occur when the engine and water pump get hot, expand, and begin to leak. Another common location for the water pump to leak is through the vent hole. Antifreeze stains here indicates that the internal seal which keeps coolant away from the bearing is defective. Alternatively, some water pumps may fail because this bearing will wear out before any leaks develop. Once again, you simply need to inspect the shaft for play or noise.If either of these conditions exist, it's time to replace the water pump. Before you begin, inspect the coolant. If the coolant is old and dirty it would be a great time to have it flushed. Complete the draining and flushing part of the procedure before the old water pump is removed.

Removing The Old Water Pump

Start by disconnecting the battery to ensure that nobody can starter the engine (or turn it over) while you are working on it. Then, loosen (but do not remove) the water pump pulley and/or fan bolts. The belt(s) will usually provide enough tension to allow this, but in some cases you may need to use a pry-bar to keep the pulley from turning. Next, remove the drive belts or serpentine belt. If the car is equipped with drive belts (V-Belts) you will need to loosen the adjusters or accessory mounting bolt that keeps it tight. This will often be the top mounting bolt on the alternator or power steering assembly. If the car is equipped with a serpentine belt (Multi-V Belt) you should find a spring-loaded idler pulley that must be unloaded to let the belt slip off. Idler pulley arms often have small "square" holes in them designed to fit with a 1/2" or 3/8" ratchet (without a socket). Now you can remove the water pump pulley and/or fan bolts and remove the fan and pulley. It may be helpful to remove the radiator shroud in order to have room to remove the fan from the engine bay. In other cases, simply leave the fan in the shroud until you are reinstalling it. Now remove the bolts holding the water pump to the engine or housing and disconnect the radiator and heater hoses. Used coolant will now drain out so be sure to have a large drain pan under the vehicle to keep it from spilling onto your driveway. Now, remove the water pump and clean the old gasket material from its mating surfaces. Use a garden hose to rinse off any old coolant from the engine and from around the engine bay.

Installing The New Water Pump

Before installing the new pump, take a moment to ensure that it matches the size and shape of your old unit. The shaft should spin freely with very little-to-no play in it. Take a look at the mating surfaces to ensure they are clean. Most major auto parts stores sell remanufactured water pumps which in some rare instances have endured in their previous life, severe corrosion around the mating surfaces. Any rough edges or pitting is a sign that should request a different unit. Reinstall the new water pump and gasket in the reverse order as the removal. Don't forget to reconnect the battery and check that the belts are tight and routed correctly. Before starting the engine you will need to fill it with new coolant.

Mixing Antifreeze

The general rule of thumb for mixing antifreeze with water is 50/50. This applies to most climates and virtually every type of concentrated antifreeze. In very cold climates, a higher ratio may be desired. Using any water suitable for drinking is acceptable; however, distilled water a better choice. Distilled water does not contain any minerals, which can leave deposits in the cooling system. Lastly, antifreeze and water do not need to be mixed in separate containers before adding to the system, nor should they. If you used water to flush the cooling system, there will be a considerable amount of water remaining when you begin. This means you will need to add a higher proportion of antifreeze to reach the desired coolant mixture. There is no effective scientific method of doing this, except to check the mixture with an antifreeze tester after it has been given time to blend and adjust accordingly. It is not that difficult and does not need to be done extremely precise.

Filling Procedure

Fill the radiator and reservoir and start the engine. As the engine runs, coolant will begin to circulate and the level will fluctuate. Continue adding coolant to keep the radiator near full until the engine reaches operating temperature. Rather than fill it right to the top, leave a little space in the filler neck. Air, trapped inside the system, will work its way out and can splash the now-hot coolant out. Turn the car's interior heater on. Shortly after the engine reaches operating temperature, the thermostat will open. When this happens, you'll notice a sudden drop in the level of coolant in the radiator as the system takes new coolant in. This may happen a number of times, until the system is completely full and free of air pockets. It is sometimes difficult to remove all the air trapped in a system; it simply takes time. Take care, as the engine will now be very hot and can cause serious burns.


When you arrive at the auto parts store, you are likely to see plenty of brands of antifreeze. Most antifreeze falls in two categories: Regular and Long-Life. Your vehicle owner's manual will specify a particular type of coolant and an employee should be able to assist you in finding it. Regular antifreeze is green in color, while long-life antifreeze is orange or pink. Long-life antifreeze must be used in vehicles that are designed for it and may be substituted when flushing, for regular antifreeze. Along with the various types of antifreeze you will notice an assortment of cooling system treatments.

Steering &Suspension

Delphi Steering & Suspension parts are designed to replace the origonal manufactures part,the quality of Delphi Products is second to none,and are used on many of today's leading car manufacturers assembly lines.

Every vehicle manufactured relies upon some type of suspension design for motion control and directional navigation. These basic designs are the Short Arm Long Arm (SALA) and the MacPherson Strut systems. There are countless variations of these principle designs, so only the basics will be discussed. For specific application material, refer to the vehicle repair manual.

-Control Arm suspension
This is commonly referred to as short arm/long arm (SALA) due to the upper control arm being shorter to allow for inward positioning of the upper ball joint for SAI. During bounce and rebound the upper control arm moves over a greater angle causing more sideways movement at the top of the tire than at the bottom. This keeps the tires flatteron the road during cornering lean. The arms are held to the frame with bushed shafts or bolts. These shafts allow movement of the control arms in the up and down arc. Usually the upper control arm is used for adjustment of the camber and caster. This adjustment can be slot adjustments, cams or shims.

-SALA Adjustments
The SALA suspension systems rely on basically three types of adjustment for the CAMBER and CASTER.
1) Shims may be used between the control arm and the vehicle frame to space the control arm to the desired position.
2) Slots are also used to allow movement, and the control arm is then secured in place with bolts.
3) Cams at the pivot point may be used to force the arm to the proper position. Usually all three types of adjuster provide movement at both the front and the rear of the control arm. To change camber only, move the front and rear in or out the same amount. To change caster only, move the front and rear in opposite directions by the same amount.

-Control Arm Bushings
Always inspect the control arm bushings in their natural position, with wheels on the groun. Look for obvious deterioration and breakage. Make sure the bolt or shaft is going straight through the center of the bushing. If not centered, they could cause variations in alignment angles during driving. When replacing these bushings, do not tighten completely until vehicle is lowered to its normal ride position. This will assure the bushing does not have a twist which will lead to premature wear.

-MacPherson Strut
The MacPherson strut is a clever design using fewer parts to reduce costs. The MacPherson is generally made up of a shock absorber, spring, and upper bearing plate which rotates when turning. This unit takes the place of the upper control arm, so most alignment adjustments are made here. To inspect for failure, look for oil leaks or bends in the rod. Check the vehicle for bounce and rebound, the vehicle should not bounce more than two and one-half times.

-Ball Joints
The ball joint is a ball with a tapered stud, a housing and a bearing surface. This allows the ball to move in a circle or in an arc, but not in or out, much like a shoulder joint. Most suspension systems use ball joints at th some point to allow a circular motion. Ball joints are usually either compression or tension loaded joints. The compression loaded means that the weight of the vehicle will push the ball into the housing. The tension type will be pulling the ball away. In either case the ball will be in constant contact with the bearing surface. Usually the load carrier or compression joint will be the one closest to the spring or torsion bar. The other will be the followerer.
----Checking the Ball Joint
------Checking for Axial Play
Before checking, the ball joint should be unloaded (have weight removed from them). The conventional SALA system locates the weight carrier on the lower control arm. The spring or torsion arm also makes contact here. Place a jack under the lower control arm and lift until the tire just clears the floor or rack. Place a dial indicator base on the control arm, with the dial placed on the steering knuckle. Zero the dial. While moving the tire up and down, read the dial change and check to see if it is within manufacturers specs. Some other tupes of modified strut place the spring or weight carrier on the upper control arm. These are checked by jacking vehicle by the frame and placing a suitable wedge, available from alignement tool manufacturers, to hold the arm away from the frame.


Delphi has one of the widest ranges of E90 approved brake pads, shoes and brake discs available from a single source, resulting in friction products that perform to within plus or minus 15% of the original equipment specification.

With a range of nearly 800 pads and 400 shoes, every Delphi product is supplied in sealed, tamper evident packages, complete with unique E90 reference (where applicable) and comprehensive fitting instructions.

Brake Pads and Shoes - The benefits

  • O E derived materials and specification to match the braking performance of the original fitment.
  • "Green lining" performance ensures pads reach optimum braking performance as soon as they are fitted.
  • Specially formulated friction materials to reduce brake dust - providing cleaner wheels.
  • OE chamfering specification ensures swift bedding in and minimses noise.
  • OE grooving specification enhances performance in the wet and reduces aqua-planing.
  • Noise suppression shims, bolts, wear leads etc all matched to OE specification and performance.
  • Each pad is manufactured on state of the art machinery to maintain the high level of quality and excellent performance our customers expect from the Delphi Lockheed brand.

Fittings and Accessories

There are a number of different types of fitting accessories, they can be springs, clips, wear indicators or pins. These fittings vary according to the manufacturer. Some mechanics will re-use the old fittings when fitting new brake pads/shoes. This is not good practice because all of these fittings are made of metal.

During the lifetime of a set of brake pads/shoes the fittings are exposed to stresses, strains, moisture, salt and temperature variations which can fatigue the metal and cause the parts to lose tension or break all together. If a spring that holds a brake pad in position loses tension it could result in incorrect contact between the brake pad and the disc whilst braking. Incorrect contact can lead to premature wearing of both brake pads and discs.

Delphi Lockheed Filter Range

Delphi’s extensive range of filters brings together the brands Diavia and Diesel’s CAV, providing a filtering solution for over 97% of the cars and light commercial vehicles on European roads.

Air, Oil and Fuel filters are fundamental to the performance of an automotive engine. In order that an engine meets fuel efficiency economy and emission targets, these three filters must remove all harmful contaminants and provide peak performance through the vehicle manufacturer's recommended service period.

Delphi Air Filters are designed to operate in hostile environments within extreme temperature conditions and prevent contaminants from entering the engine management system.

Delphi's Oil Filters are designed to handle large volumes of oil, removing particles of metal, carbon and other debris resulting from the combusition process. These filters are available with many optional features depending on engine requirements. For example, features such as anti-drain, element relief and anti-syphon valves or anti drain tubes.

Delphi's Petrol Fuel Filters are designed to protect an engine's sophisticated petrol injection equipment and engine management systems by trapping contaminants that may be present in the fuel, or rust and sediment from the fuel tank.

Delphi's range of Diesel Fuel Filters previously sold under the "CAV" brand, serve both Original Equipment and the Aftermarket. By working closely with the world's leading manufacturers, Delphi's diesel product range supports over 550 vehicle and engine manufacturers applications from Audi cars to Volvo buses. Delphi's diesel fuel filters protect diesel-injected engines from contaminants as well as removing small droplets of water often found in diesel fuel.

Delphi's range of "Diavia" branded high quality cabin filters improve the quality of air inside the car, providing additional protection to allergy sufferers and reducing traffic film build up on internal surfaces. Special micro-fibres in the filter media trap both large and small atmosphericparticles, from pollen, industrial dust and soot through to bacteria, spores and exhaust particles.
