Quality Gasoline For Vehicle

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 ...

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 p...

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 inexp...

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...

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 include...

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 pai...
