Transponder User Guide

Simple mechanical auto locks are rapidly losing ground to the next generation of lock technology — transponder keys. In this innovative system, an electronic chip (the transponder) imbedded in the key transmits and verifies a code with the car’s on-board computer systems, allowing the car to start. If someone attempts to start the vehicle without the correct programmed key the car will not start.

Transponder technology represents a major advance in theft protection — and a profitable opportunity for you. Since its introduction in 1996, transponder key use has grown to over 70 million cars in North America today. And with replacement costs currently averaging $50 to $300 per key, your reward in servicing the technology will match the vehicle owner’s satisfaction of being protected by it.

GeoTool Pickup Truck Antenna Mount Size Guide

GeoTool Pickup Truck Antenna Mount Size Guide

The rulers and templates will make it easier to measure stake pockets in tenths of an inch, just like in the metal shop. You will use these to accurately measure the dimensions of your stake pocket. Before cutting out and using the rulers and templates, make sure the rulers on this page are the correct size by comparing their length your own ruler. If the length is not correct, enlarge or decrease the size of the printout (using the print dialogue box in windows) make them the correct length. With my computer I had to increase the size of the printout by 104%. When the printed rulers are the correct length, the mount block templates will also be the correct sizes. Cut out the ruler at the right, including both the blank portion and the printed side.

Fold the ruler at 90° along the midline to increase stiffness of the ruler, and then use it to accurately measure the depth of the stake pocket. Use the two rulers together to measure the size of the internal mount if it is smaller than the outer stake pocket, or if the pocket has internal protrusions. Cut out the Mount Block Templates that most nearly fit your stake pocket size, and use them to determine the correct top opening dimension. Remember, some stake pockets have protrusions (i.e., Pre-2000± Dodges) or smaller interior dimensions (Toyota Tundra).

Guide to R134a Compressor Compatibility

Guide to R134a Compressor Compatibility

the survivability of a given compressor when retrofitted to R134a has been heatedly discussed for several years. First we need to clarify whether we are discussing a CARQUEST remanufactured compressor or an Original Equipment (OEM) compressor that came with the vehicle. When considering retrofitting to R134a all CARQUEST compressors are up to the task, with the only recommendation being that the GM DA6 be replaced with an HR6 compressor. When it comes to OEM compressors the only guide that should be accepted as true would be the OEM guidelines themselves.

GM:
• The DA6 is not recommended for use after the 1987 model year for R134a use. The CARQUEST HR6 should be used to replace the DA6 whenever the customer considers retrofitting to R134a.
• GM reported that the R4, which appeared in pickup trucks from the late 1980’s to the early 1990’s and was designated as a 16-valve compressor, is not a candidate for retrofit. This compressor had a gold label attached to it from the manufacturer. The compressor should be replaced with a new, or a remanufactured CARQUEST R4 compressor.
• GM requires the use of a special V5 retrofit PAG lubricant for use with replacement GM OEM V5 compressors. The use of this special lubricant is not required on CARQUEST remanufactured units, therefore we recommend replacing the compressor to a CARQUEST unit.

2004-2007 Mazda RX-8 ENGINE CRANKS NO START Service Bulletin

2004-2007 Mazda RX-8 ENGINE CRANKS NO START Service Bulletin

Some vehicles may experience difficulty starting (cranks no start). This may occur after driving the vehicle a short distance without engine reaching normal operating temperature. Examples: starting a vehicle and moving it to wash it, engine stall due to mis-application of clutch then restart. This commonly occurs at port facilities or dealer lots where vehicles are frequently started cold, moved for short distances and then turned off. This concern may also occur due to low cranking RPM during engine starting.

A cranks, no start condition may be caused by fuel flooding resulting in either fouled spark plugs or lower than normal compression. Carefully follow REPAIR PROCEDURE “A” and refer to VIN application to determine necessary repair action.

NOTE:
• After repairs, provide customers with CUSTOMER INFORMATION on the last page of this bulletin (for customers to try after a “CRANKS, NO START” condition, before towing to dealership).
