Overlooked Maintenance Items: Wipers and More More than 80 percent of the vehicles that have been inspected at community car care events across the country over the past year were in need of service or parts, reports the Car Care Council. This reinforces the need for consumer education about the benefits of regular vehicle care and maintenance, especially as the number of years owners keep their vehicles continues to increase. Top problem areas typically found include the need for oil changes, windshield wipers, air filters, and improperly inflated or worn tires. Forgotten Wipers Wipers appear to be one of those items that drivers forget about when they are not in use. However, once the rain starts to fall, the need to replace worn wipers becomes evident rather quickly, and good visibility has a major impact on driver safety. The replacement interval of wipers is based on several factors, including operating conditions (winter conditions are tough on wiper blades, yet wiper blades can deteriorate faster and need more frequent replacement in sunsoaked desert states), frequency of use, and the material and type of wipers. Wiper blades should be inspected A new battery does not develop its full performance capabilities until it has been through several discharge/charge cycles. This means a new battery may not be capable of producing its optimum current and cold cranking amps (CCA). If a new battery that has not gone through a cycling period is tested using a conductance-type battery tester, the resulting CCA may be lower than indicated on the battery’s rating label. This could lead to condemning an otherwise good battery. Conductance is a measurement of a battery’s current producing capability. Conductance testers can accurately identify batteries that have reduced performance after being in service, but should never be used to determine the state of health, state of charge or CCA rating of a new, never installed battery. Also, conductance testing of new batteries should never be used to determine the warrantable condition. every six months. Streaking or chattering blades as well as worn or split rubber are signs that it’s time to replace the wiper blades. ACDelco wiper products feature: – Beam wiper blades — the latest in wiper technology – Performance blades that feature pre-installed adapters that match a vehicle’s arm type for quick installation – Aerodynamic designs that help prevent windlift – Broad range of sizes and types of blades, including low profile and hard-to-find applications – Materials and finishes (polymer or carbon steel) that are designed to resist rusting, chipping and bending – Coatings on rubber parts that help reduce streaking, friction and noise – Virtually all-makes and all-models coverage Maintenance Recommendations To help ensure the reliability and safety of a vehicle, as well as to extend vehicle life, the Car Care Council suggests these preventive maintenance To check the condition of a battery prior to installation to be sure there is adequate voltage to start the vehicle, measure open circuit voltage (OCV) using a digital voltmeter (DVOM). An OCV of 12.24V is adequate to provide the power requirements for starting most vehicles under most conditions. The battery should be in service for several days before performing a conductance test. 4 steps — many of which are put off or overlooked by drivers — be recommended to service customers. Checking these items is especially timely after a harsh winter’s worth of driving: – Change the oil and filter regularly according to the owner’s manual maintenance schedule. – Inspect the tires for proper wear and check the tire pressure at least monthly, including the spare. – Have the alignment checked at least annually. Potholes and other road conditions can take their toll on a vehicle’s steering and suspension. – Check the hoses and belts — which are critical to the proper functioning of the electrical system, air conditioning, power steering and the cooling system — for cracks, brittleness or other signs of excessive wear. – Inspect the windshield wipers and lights on the vehicle. All of these components are often neglected wear items that are needed for safe and reliable vehicle performance. – Thanks to Chris Vermette Improper Use of Conductance Testing on New Batteries Don’t use a conductance tester to measure the performance of a new battery. Battery Testing Procedures Follow these tips when using a conductance tester to ensure accurate test results. Using non-approved adapters or improper test procedures can lead to failing test results for batteries that are not defective. Be sure the battery in the tester is good or you may get inaccurate results. To check the conductance tester, be sure OCV on the tester matches the OCV measured with a known-good DVOM (may vary slightly due to different internal resistance). Be sure to get good connections between the battery terminals and the tester clamps. Each tester clamp has two jaws. Each jaw is wired to a different part of the tester, and it is essential that both jaws make good contact. If the connections to the battery terminals in the vehicle are in doubt or continued on page 5
Labor Times Now Available on WIP Why use two sources to check mechanical labor times and parts pricing and availability? ACDelco’s WISE Internet Parts (WIP) now offers users the ability to do both in one application, at no additional charge. WIP, ACDelco’s Web-based parts catalog application, provides fast parts inventory access and compre - hensive parts ordering. ACDelco WIP subscribers can check inventory and order parts online anytime from WISE-enabled ACDelco Warehouse Distributors. Now, labor times also are only one click away. Using the labor time feature will help subscribing service centers to quickly create parts and labor estimates. This new feature does not apply to TurboPart WIP users. Parts and labor or labor only can be displayed in WIP. the tester displays REPLACE BATTERY or BAD CELL - REPLACE, disconnect the battery being tested from the vehicle. Retest the battery with both of the vehicle’s battery cables disconnected from the battery. When using an adapter, be sure the adapter makes good contact with the lead terminal surface on the battery. Never use steel bolts, nuts, washers, etc., when testing a side terminal battery. Only use the adaptors included with the conductance tester. The coating on other adapters may affect the tester’s accuracy. Battery Warranty ACDelco batteries are covered by a comprehensive warranty program. Any independent service center can accept an ACDelco battery that is under warranty and not functioning properly from a customer for return, even if the battery was purchased from another retailer or service center. ACDelco will warrant the battery, and in the process, the service center may earn some additional service business and customer loyalty. – Thanks to Mike DeSander and Brad Busboom To display labor times, users will identify and search for parts as they have in WIP previously. Build the vehicle for which the parts are needed by selecting the year, make, model and engine, or enter the VIN. Next, select the parts group and subgroup. Once users have identified the vehicle and parts they are interested in, click on the Display Parts & Labor button or the Display Labor Only button. Labor times for the selected parts will be displayed below the parts information. The labor multiplier value used to calculate the labor times also can be changed. Click the Edit Labor Multiplier button to increase or decrease the multiplier. 5 The addition of listing labor times in WIP is just one of many benefits. WIP also provides: – The ability to place parts orders anytime 24/7 with local warehouse distributors – A direct link to local warehouse distributors using your PC and Internet connection, no additional hardware or software is required – Access to the inventory of local warehouse distributors to check parts pricing and availability To learn more about WIP, visit www.acdelcotechconnect.com, call 1-800-825-5886, prompt #3, or contact your local ACDelco representative. – Thanks to Bob Stewart Labor times for parts searched in WIP. Expanded Wiring Sockets and Pigtails Search Tool The wiring sockets and pigtails search tool on www.acdelcotechconnect.com has been expanded. This on-line reference source offers a menudriven search feature that can narrow the search according to brand, number of cavities and gender. With photos of each pigtail and wiring socket, you also can visually match the part you are replacing with the new part number. All of which makes it easier to identify wiring sockets and pigtails for GM and non-GM vehicles. To access the wiring sockets and pigtails search tool, go to www.acdelcotechconnect.com and click on the Automotive Systems tab and the Product Information link. – Thanks to Bob Stewart
