How To Know About Quality Of Gas Used For Vehicle
Buying Cheaper Gasoline For Car
Q: In New Hampshire few Wholesale Food Clubs sell gasoline at least 10 cents a gallon less than brand names. How can they do that and can this product be harmful to an engine?....Gerald.
A: First, ask yourself why you go to the Wholesale Club to buy their product? The answer more often than not is price. When a company as big as these wholesaler's want to buy product they have unsurpassed buying power. They go directly to the manufacturer and order, not a truck load, but train loads of product. As for gasoline? Buying power, combined with volume of sales, allows for the pricing you're seeing. There are state and federal laws that govern gasoline. The manufacturer and retailer of gasoline are open to a big pile of trouble if the gasoline being sold is mislabeled or does not meet state and federal standards. Hey, whenever I'm buying a 40lb bag of cheese curls I fill my gas tank too!

How To Turn OFF "check engine light"
Check engine light reset
Q: Please Tell how to turn off my "Check Engine" light? For 1997 Jeep Grand Cherokee Laredo, 4.0 L. An auto parts store guy read the code for me, and said he thought it would turn off after about 15 or so "drive cycles". Any truth to that?
A: The “Check Engine” will turn off by itself if the problem is no longer present after about 3 drive cycles. Each time your vehicle is started and driven the computer’s software commands a wide variety of tests to be performed and monitors various sensors while the vehicle is being driven. A drive cycle is when the vehicle/engine sets long enough for the coolant to drop below a specified temperature. Then the engine is started and the vehicle is driven at different speeds and allowed to reach full operating temperature. The reason for this? The computer not only tests the system, it also monitors for range of operation. Certain tests can only be performed when the engine is cold while others are performed when the engine is hot. Each time the engine is started the computer performs over a hundred checks and tests of your vehicle’s emissions system, which includes the automatic transmission too. If your problem has been corrected, generally the “Check Engine” light will turn off within a day or two of normal driving. If the light does not turn off, there is a system problem and diagnosis is needed.
Squeaking Brakes
Jeep Cherokee Brake Squeaks
Q: Brake job done on our 1996 Jeep Grand Cherokee back in April of 1998. A few weeks later I went back because the brakes were squealing. They said, "It's supposed to sound like that because there is no more asbestos in the brakes". They also said, "It will wear off after I run the car a while and put on a few miles". I recently took it back again in June of this year. Again they said, "Nothing is wrong, they are suppose to squeal". I asked them," How come the brakes don't squeal on the new cars in this lot?" No reply! My question to you. What do you think? Is there anything I can do about this?... Squeaking brakes!!!!!!!
A: Well, you've got them. The brakes are not supposed to squeal on your vehicle, but the noise doesn't mean the brakes are unsafe, there could be other factors. The squealing noise is an indication that not all the necessary procedures were followed while the brake job was being performed, or that the friction material used on the brakes was of questionable quality. The high frequency squealing sound, when braking, is caused by brake pads vibrating. Improper assembly procedures are the most common cause for brake squeal. Proper inspection, preparation, cleaning and lubrication of braking components is critical in preventing brake squeal. Also, realize that not all braking materials, brake pads or shoes, are created equal. Discount brake pads or shoes are not of the same quality engineering and material as original equipment or quality aftermarket brakes. It's like re-capped tires compared to radials tires. They both do the same job but...

Evaporator Coil Replacement
Replacement Evaporator Coil For Jeep Cherokee
Q: A query from inexperienced mechanic, I was wondering if I am able to replace the evaporator coil for 1996 Jeep Grand Cherokee with a 5.2 liter engine. Where can I find complete instructions on how to do it?
Please Help !!!!!!!!!!!!!
A: First, you would have to define inexperienced. I’m a believer that anyone can do about anything they put their mind to. The main tools you’ll need for a job such as replacing an A/C evaporator in your Jeep is patience, attention to detail and information. Information can be found but the detailed information you need, to maintain patience, will need to be borrowed or bought. You can purchase factory information and diagrams on-line. An example would be found at alldata.com. ALLDATA Information Systems has a Do It Yourself (DIY) section that allows you to purchase vehicle specific information. If you want to DIY this job, be organized. Have information and allow plenty of time. If you’re inexperienced, tackling a job like replacing an A/C evaporator without good information will have you throwing tools down the driveway. In which case, you should park your Jeep to allow for easy access for the wrecker, in the event you throw all your tools down the driveway.

All Gauges Not Working
Troubleshooting Gauges Issues On Jeep
Jeep Cherokee, Gauge Problems
Q: All gauges: The speedometer, tachometer, and gas gauge on 1996 Jeep Cherokee not working.Tried replacing the instrument cluster pod and still have the same problem. When they went out they would work off and on and the needles bounced around at times, then went out for good. Any suggestions?A: Start with checking the fuses. The number 7 fuse in the fuse panel is a main player in powering up the instrument cluster in your Jeep. You should also realize that the action of the instrument cluster displays (speedometer, tachometer, gas gauge, etc.) are primarily a result of information processed by a computer called a Body Control Module (BCM). Because so many of your gauges are acting strangely the BCM is suspect. The BCM does have built in diagnostic abilities that can be accessed with a scan-tool. Virtually all of the lights and gauges on your dash can be operated via the scan-tool, through the BCM, for confirming function. Before replacing any more costly instrument clusters or installing a replacement BCM (the cost of a replacement BCM will create respiratory problems), be sure to check the fuses and electrical connectors. Proper diagnosis will save you money.
Ignition Coils Burning
Jeep Grand Cherokee Ignition Coil Burns Again n Again
Q: For Jeep Grand Cherokee. Idling very slow. I replaced the plugs wires and fuel filter but, still idled slow. I sent it to a mechanic who replaced the ignition coil and distributor pick up and it ran fine for one day. I took it to work and when I went to leave it wouldn’t start. I checked it and there was no spark so I took it back to the mechanic and he said the new coil went bad. He replaced it and it ran for 2 days then I went to drive it home from work and it wouldn’t start. I purchased another coil myself installed it and it fired right up. Do you have any idea why it’s burning up the coils?
A: Before replacing the coil too many more times you may want to go the Jeep dealer and buy an updated ignition coil and harness. The ignition coils were known for shorting internally, causing a variety of running problems. The update called for a lower internal resistance coil and a modification to the wiring harness that included an external resistor. If you’re installing an aftermarket coil that has a lower internal resistance without the wiring harness modification you’ll just keep burning out ignition coils.

Technical Service Bulletin Recalls For Jeep Cherokee
Safety Recalls For Jeep Cherokee
Q: Need listing of the recalls (safety and other) for 1994 Jeep Grand Cherokee. Can you help me find this list? All I am able to find are some safety recalls and next to no Service Bulletins.
A: Any person can check on safety recalls by calling the National Highway Traffic Safety Administration at 888-327-4236 or at www.nhtsa.dot.gov. As for TSB’s (Technical Service Bulletins) that is a different story. First you have to understand that a TSB involves a problem. The first problem with a problem is its definition. In the Webster’s big book a problem is defined as 1. a question proposed for solution or consideration. 2. a question, matter situation, or person that is perplexing or difficult. 3. in mathematics (hey this doesn’t count here forget it, need the space) The problem is there is no #4. who pays to fix the problem? Is it the tech? No, he/she works for the dealership. After all you can’t feed a family or own a house if you don’t get paid. The dealership? Yea at first they’re stuck with the cost until they get the money out of the folks who designed and built the vehicle. Of course the first thing they say is there’s no problem- must be your techs. Once enough dealerships are screaming, (just like their customers) the maker realizes Oh, maybe there is a problem. In the interim the solution, or an in the field fix is found. Here’s where the cost of a TSB really jumps. The maker has to get this information out to all the other dealerships, to let their techs know how to fix the problem, which may include redesigned parts. Also if the car is new enough the repairs may be for free (eegkads!). Getting the TSB out to all the dealers and techs, not to mention any parts, costs big bucks. Loss of big bucks means loss of big bucks! There are research and development costs, warehousing, distribution costs, transportation & delivery costs, installation costs, not to mention the white shirts trying to justify their corporate existence, it just plain cost money! Then a person like you or me comes along and asks for this information for free? Right! Hey they got the investment and need a return. Even the folks at ALLDATA Information Systems have to pay for the information and the right to reprint it. Whether it’s computers, medicine, law or cars information is not free. Someone (that is you or me) has to pay for information in its final form.
