The sensible alternative to silicone coolant hose

Blue Stripe Coolant Hosebeats silicones price and performance

Blue Stripe hose is made with EPDM (Ethylene Propylene Diene terpolymer) a compound known for excellent sealabilityand low water permeation. Unlike its predecessors in the 60s and 70s, this hose resists electrochemical degradation (ECD),the primary cause of most early coolant hose failures. This discovery also led to the realization that silicone lasts so longbecause of its resistance to ECD not high temperatures.

Blue Stripe coolant hose beats silicone because it:1. Bonds better to fittings for greater sealability, fewer cold leaks and EPA concerns.2. Reduces water permeation through hose wall, decreasing radiator topping and coolant concentration imbalances. Silicone

permeates water 5 to 20 times faster than EPDM (depending on the operating temperature).3. Is more robust than silicone clamps are less likely to sink into and damage the hose.4. Costs less and performs better than silicone.

Blue Stripe Molded Coolant HoseRecommended For: Upper, lower, by-pass, heater and othercoolant applications. Factory molded to fit specific applica-tions. Installs without buckling, bending out of shape, or strain-ing at connections. Compounded to resist electrochemicaldegradation - the leading cause of hose failure. Available in 3 8"thru 3" inside diameters. Meets OEM specifications. Meets SAE20R4 and 20R3 Type EC Class D-1 requirements.

Hose ClampingClamping hose to fittings is an art. Many things affect how well a connection will maintain integrity and prevent leaking. With properselection of clamps, fittings and torquing technique, a quality connection can be achieved. With proper maintenance of the connection,leaking will never be a problem.

Things That Minimize Leaking1. Torque Level of the Clamp

A. Normally, the higher the torque level reached without damaging the clamp, hose or the fittings, the less chance of leaks.

B. A clamp that evenly distributes torque normally attains higher torque without damaging connection. Any localized forces willdamage connection at lower torque levels.

C. Rate of torquing influences final torque after rest. A clamp torqued to maximum in 10 seconds will have 70% more restedtorque than when torqued to maximum in 3 seconds.

D. Retorquing clamp after 10 minutes will increase the final rested torque level.

E. Torque level decreases as ambient temperature decreases.

F. Torque level decreases with time due to compression set of the rubber. Periodic retorquing of clamps is advised.

2. Conditions of NipplesA. A beaded nipple offers better sealing and retention characteristics.

B. The smoother the finish of the nipple, the less the tendency to leak under the clamp. Irregularities can channel fluid pastthe clamp. Avoid painting the nipples.

C. Adhesion of hose to fittings will aid leak prevention. Brass and cast iron adhere to common rubber compounds after sometime in service.

D. Use of sealants and viscous gels will aid in leak prevention. Be sure the substance is compatible with the hose and coolant.Also the clamp/nipple configuration should prevent hose from slipping off the nipple.

Choosing a Hose ClampThere is a variety of clamps on the market. In choosing a clamp, look for one which most evenly distributes the torque around the clamp,and maximizes torque level without damage to hose or fitting.

Types of Clamps1. Band Clamp Tangential Screw. This clamp (Figure 1) attains high torque levels and distributes torque evenly. Localized

force beneath the housing can cause premature deformation of the nipple. Extrusion of rubber through the slots in the bandmay occur at high torque levels.

Figure 1

1-10

Hose Clamping continued2. Banded ClampRadial Screw. This clamp is best for low torque applications. Force is localized under the screw causing

deformation of nipple at medium torque levels.

3. Two-Wire Clamp. This clamp (Figure 3) evenly distributes an extra high torque level. Will not damage hose unless the covercompounds are tender, such as silicone. Inexpensive.

Pressure And Temperature Requirements Chart below showsrelationship between pressure and temperature for various concen-trations of coolant fluids. Maximum temperature attained can befound by using pressure cap setting. Normal operating pressure andtemperature usually will be less.

Pressure In a closed cooling system, pressure is depen-dent upon temperature and type of coolant fluid. Usually,system is sealed with a pressure cap which opens at pre-setmaximum allowable pressure. Temperature at which this oc-curs varies with concentration of coolant fluid. A cooling sys-tem in good condition will normally operate below thismaximum pressure and temperature.

V-Belt Part Numbering SystemsWhen it comes to selling V-belts, there is really only one thing to keep in mind: theres no suchthing as a universal belt part numbering system.

Its common practice for all belt manufacturers to assign part numbers that are descriptive of thebelts critical physical dimensions: the top width and circumference. The problem is that there areno industry standards in place to ensure consistency between the way one manufacturer measuresa belt with that of another. As a result, the circumference measurement can represent any of threepossibilities: the outside, the inside, or a measurement referred to as effective length. To com-pound the problem, circumference length and top width can be expressed in increments of varyingfractions of an inch-tenths, sixteenths, thirty-seconds, etc. or even in metric scale.

What all this means is that you can never rely on matching belt part number to belt part number be-tween manufacturers. Always check the physical dimensions to guarantee a like-fit.

To compensate for the lack of consistency across belt manufacturers, the competitive interchangecontained in this booklet compares Gates, Dayco and Goodyear part numbers using the outsidecircumference as the common denominator.

Alliance Belt Numbering System Alliances all makes belt numbers are 5 digits in length. The first two digits denote the top width in32nds of an inch. The last three digits indicate the outside circumference in inches with the lastdigit expressing 1/8 inch increments.

Example: GT17 3321/8" increments of outside circumference = 1/4"

Full inch increments of outside circumference = 33"Total Outside circumference = 33 1/4"

Top width = 17/32"

Example: GT15605Outside circumference = 60 5/8"

Top width = 15/32"

When using the competitive interchange, please remember that all belts have been comparedbased on top width and outside circumference. While each Alliance belt may not be identical in di-mensions to a belt listed in the interchange, the Alliance number should be suitable for many appli-cations of the competitive belt.

Also, keep in mind that due to varying pulley ride heights and available length adjustments inherentin certain applications, some belts will provide good performance across several applications.

All-Makes Belt Tension Recommendations(Supplied by Power Transmission Division of Gates Corporation)

Belt tension maintenance is critical to the operation of your accessory drives and the life of your belts. Please use the followingprocedure as guidance when tensioning your belts.

Procedure:1) Install new belt and tighten to recommended new belt installation tension.

2) Run drive for 10-15 minutes with fan and accessories ON (to build heat in the belts).

3) Turn off engine and re-measure tension.

4) Tension should be within the recommended used belt tension range.

5) If tension is below the used belt range, re-tension to within used belt range.

6) Always maintanance the lowest tension at which the belt wont slip. If it slips, retension the belt.

IMPORTANT NOTE: All new drive system tension requirements are specific to the drive. The recommendations below are rule-of-thumb (based on the tension carrying capacity of the All-Makes replacement belt). Please consult your engine service manual forspecific application requirements as component damage could result from over-tensioned belts.

Worn Belt Identification and Replacement TipsRemember, belts dont last forever. After 100,000 miles, they can go at any time. And with todaysbelts, you cant tell just by looking at them. So if your customers truck has gone 100,000 miles be-tween minor overhauls, save him some big trouble...recommend he replace the belt.

Furthermore, if a belt exhibits any of the following tell-tale signs regardless of its accumulated mile-age, it is a candidate for replacement.

1. Glazed or Shiny Sidewalls

The friction created by a loose belt slipping in thepulley causes the belt sidewalls to become slickand shiny. These glazed sidewalls lose their grip-ping strength; and the belt slips even more. Greaseand oil on the pulley can also cause this condition.

2. Cracks

Deep bottom cracks that appear at regular inter-vals are caused by the belt turning around atoo-small pulley (usually the alternator)-the un-dercord is being stressed to the breaking point.Smaller, irregular cracks, however, usually justindicate a belt that has weathered a long life.

3. Missing Chunks or Brittle, Separating Layers

A belt that is failing apart in layers could be avictim of oil. Oil and grease are a rubber com-pounds worst enemies. Oils weaken the com-pounds bonds making the belt soft, spongy andconsiderably weaker. Eventually, such a belt willslip. These oils can come from belt dressings(which should never be used) or from leakingengine parts.

4. Jagged or Streaked Sidewalls

Pitted or streaked sidewalls are the result of aforeign object in the pulley (such as sand orgravel) or a rough pulley wall surface. Foreignobjects can get into a pulley from an oily, stickybelt. Regular cleaning of drive components helpsprevent this problem.

Worn Belt Identification and Replacement Tips

5. Tensile Break

A large foreign object in the pulley can cut intothe belt and break the tensile cords. A tensilebreak may occur, but go unnoticed, when a beltis forced or pried on during installation.

6. Uneven Ribs (Micro-V belts only)

Pulleys must be clean at all times on a Micro-Vdrive. Foreign objects in the pulley can erode theundercord ribs and the belt can lose its pullingpower.

7. Pilling

Pilling occurs when rubber compound from thebelt wears off and settles in the apex of theV-groove. This can cause uneven rideout, vibra-tion and belt noise if the accumulation is severe.

8. Oil Soaked

Grease, oil and other engine fluids on the beltsidewalls, or in the pulley grooves will glaze thebelt and increase slippage. In some cases, pe-troleum contamination may deteriorate rubberand lead to premature failure.

9. Chunking

Deep cracks will lead to chunking where parts ofthe ribs will break off. Replace the belt immediately.

Worn Belt Identification and Replacement TipsWhen replacing belts, there are a few key points to keep in mind to assure the long service life anAlliance Parts belt can provide:

Pulley Alignment and Inspection Before removing the old belt, check the alignment of the pulleys. If the driveshafts are not parallel or if

the pulleys are misaligned, the drive could be wearing the belt out before its time. If there is misalign-ment, you will have to adjust or replace the bent or broken pulleys, pulley brackets or shaft.

When removing the belt, do not use any hand tools to pry the belt off the pulleys. Make sure toloosen the belt enough to remove with your hands.

Once the old belt is removed, inspect the pulleys for worn grooves, foreign particles, rust or oiland grease in the grooves. If the pulleys cannot be cleaned or repaired, they should be replaced.

The New Belt Make sure the new belt you are putting on the drive is the correct size. This Alliance all makes

belt booklet contains complete crossover information to identify the proper Alliance number forthe vast majority of competitive manufacturers numbers. Be sure the new belt has the proper topwidth and outside circumference dimensions.

Matched belts must be replaced in sets. A new belt added to a set of old belts will not ride in thepulleys the same way the old ones do. As a result, the load of the drive will not be distributedevenly among all the belts. If one belt in a matched set fails, all the belts must be removed.

Tensioners are designed into the belt drive system for several reasons:1) Proper tension is maintained throughout the life

of the belt.2) They reduce maintenance by eliminating the

need to retighten belts on a periodic basis. 3) They improve belt life. Because the belt is

always at the ideal tension, the belt lasts longer.

4) They reduce the amount of tension needed by the belt, thereby increasing bearing life of accessories.

How does a tensioner work?The tensioner is a spring-loaded device consisting of eight basic parts:1. Base: stationary part of the tensioner that is

bolted to the engine block or other accessories. Each base design is different. Some base components may be very complicated, including large sections of bracketry or seals that form part of the cooling system.

2. Bushing or Dampening Shoe: a plastic ring that dampens or smooths system vibration.

3. Spring: preloaded at the factory, it provides the force to tension the belt.

4. Arm: connects the spring to the tensioner pulley. It is usually an aluminum casing.

5. Pulleys: are nylon or steel and may be flat, grooved or flat with flanges. Pulley surfaces should be inspected regularly for damage or wear. Nylon pulleys are most vulnerable to wear.

6. Bearings: that lose lubrication can fail. Do not attempt to put a new bearing in an old pulley. Replacement pulleys with heavy-duty bearings are available.

7. Dust shield: protects the bearing from the elements.

8. Bolt: connects the pulley to the arm.

Tensioner Installation and TroubleshootingA belt length variation gauge is built into each tensioner. The gauge indicates the belts length. It consists of a pointer and either two or three marks indicatingtherangeoftensionermovement.Minimumbelt length, ideal length and full take-up length are usually indicated on the gauge. The gauge window is located on or along the break between the base and the arm of the tensioner.

As a belt wears and stretches with age, the tensioner automatically moves to keep belt tension constant. As this happens, the pointer on the length gauge will move toward maximum length. When the pointer is within 5 percent of the maximum belt length mark, the tensioner is out of its useful range and the belt should be replaced. The belt has stretched, often squeals and appears loose.

How long do tensioners last?Thisvariesondutycycle,applicationandmanyotherenvironmentalconditions.Manyearlymodel tensioners and off road applications often show signs of failure before 100,000 miles. Newer, on-highway designs usually last longer.

Replacing tensioners:Tensioners most frequently fail as result of careless belt replacement. If the old belt isnt removed carefully the tensioner may spring down and crack. If the new belt is too short it can snap the tensioner. Tensioners are designed for specific vehicles, which means there isnt a universalreplacementprocedure.Consultyourvehiclesengineservicemanualforcorrectinstallation procedures.

How do tensioners fail?1. Idler bearing failure, seized bearing.2.Chippedidlers(plastictype).3. Tensioner arm cracked.4. Tensioner component wear. - Dirt/debris inside. - Bushing wear.

5. Belt misalignment. - Damping mechanism wear. - Bushing or internal component wear.6. Increased tensioner movement. - Dampening device wear.
