I have a 2004 Ram quad cab with the hemi motor, and ever since I purchased it I have had a tick noise in it and had it to three different dealers, and they all said it was normal for the hemi to have a tick in it hence the hemi tick name. Am I getting a snow job, as every hemi I have heard running has it? Thanks.
QUESTION: I have a 2004 Ram quad cab with the hemi motor, and ever since I purchased it I have had a tick noise in it and had it to three different dealers, and they all said it was normal for the hemi to have a tick in it hence the hemi tick name. Am I getting a snow job, as every hemi I have heard running has it? Thanks.
ANSWER: A lot of engines do have a ticking sound some louder than others. The tick sound is usually from the electronic fuel injectors opening and closing. If this is the noise, it is a normal sound. We use a stethoscope or chassis ear when checking for a noise complaint.
QUESTION: I own a 1999 Plymouth Neon. The a/c does not hold a charge. I had a lot of parts replaced two weeks ago and still have the same problem. What is your opinion on a/c Stop Leak? I have read both pro and con on the Internet. Thanks in advance.
ANSWER: Before we think about Stop Leak, let’s try to find the source of the leak. Have the technician charge the system with an extra dose of dye. Then look for the leak. A common problem on this car is the evaporator in the heater box. As for a/c Stop Leak, there are many different brands; some make money-back guarantees. If the leak is the evaporator and you do not want to spend the money, then a/c Stop Leak is your only choice. The a/c does not work now so the Stop Leak cannot make it any worse. Some technicians will disagree with my answer.
QUESTION: I own a 2004 Chevrolet Malibu LS V/6. My problem is there is a lot of play in the shift handle. Any ideas on how expensive it would be to repair?
ANSWER: I see a lot of shifters both floor and column mounted that have too much play. The most common problems are worn bushings and linkage mount bolts that loosen. In most cases it’s an inexpensive repair. I also see a lot of import vehicles that have stiff shifters due too lack of lubrication usually at the pivot at the transmission.
QUESTION: I own a 2005 Nissan Maxima. My problem is the ignition coils keep burning out. I have had the car to a couple of shops and now the car is in my driveway. Both shops have checked all wiring and the alternator. Do you have any suggestions?
ANSWER: Whenever I see a car with electrical parts that burn out, I will look for engine ground problems. Technicians often overlook the basics, including myself. It is impossible for one technician to know it all, and that also goes for me. When I get stumped, I will refer to outside help such as Identifix and Alldata for additional information.
