Infiniti Repair Questions and Answers


 

Question:  2000 Infiniti I30 mileage: 73,000.  When I get home from driving, I smell a burnt smell, almost like burnt wires, but it goes away right away.

Answer:  We think that the valve cover gaskets are leaking allowing oil to seep onto the exhaust manifolds.



Question: 2001 Infiniti M30 V6 3.0 mileage: 155,000. I have been struggling with a cooling problem for 3+ years - new thermostat, rodded radiator (didn't need it), new water pump (leaking-but problem existed before and after water pump replaced) electric fan operates perfectly. New radiator cap runs hotter when AC is on or stopped in traffic. NOTE: I am not losing any coolant. Now it's also running hotter even in winter months. How do I know if I have exhaust in coolant? Or, how do I know if catalytic converter is clogged. P.S. I had transmission rebuilt and I am using an external cooler for the transmission (again this cooling problem existed before and after transmission was rebuilt I will get a magnetic thermometer to put on radiator cap to check temp. at radiator VS temp gauge on dash. Thanks for your website. Zula

Answer: Most auto parts stores sell a kit to test for exhaust in the cooling system. To test for a plugged converter, drill a small hole in the exhaust pipe right before the catalytic converter. Install a temporary hose fitting and attach a long rubber hose and a 0 to 10 pound pressure gauge. With the gauge inside the car, drive up a hill or accelerate and read the pressure. Normal is 2 to 3 pounds, restricted 4 pounds or higher. The drawback to this method is the small hole will need to be welded shut after the test; a minor job if you have a welder.


Question: 1995 Infiniti G20 1.8 mileage: 101,000. Automatic Transmission. I purchased this car brand new and the first signs of transmission problems began yesterday. Once the car gets up to 55MPH, the RPM jumps from 2500 to 4500 and the transmission won't budge -- it tries to shift, but is unable to. The only way to make it from point A to B is by going under 55MPH, and as you know, this won't work on the Washington DC Beltway. I have taken it to a local Infiniti dealership and they said everything checks out fine and that they test-drove it. Well, they misinformed me, b/c when I picked up the car, I checked the mileage, and found that they hadn't driven it. They said they tested everything out on their computer and everything tested out. Help!

Answer: You might try having the transmission serviced (fluid and filter change). However, we would bet that the transmission is starting to fail in your car. Maybe you can trade it in at the dealership that said the car was fine.


Question:  1999 Infiniti G20  mileage: 106,000.  Bob/Ken, What needs to be done to remove the starter on the G-20?  The bolts that hold it come in from the opposite direction and I can barely see one of them, let alone get a socket on it.  I have pinpointed the starting problem to the solenoid...but starter and solenoid are sold as a unit, which is o k..., but I still need to remove the starter.  Can this be done at home, with the car up on ramps or is this a job for the dealer..

Answer:   If you have any doubts, it would be better and safer to have the work done by a reliable service center or dealer.  However, it you feel comfortable with your ability, a Mitchell, online repair manual for your make of car will have diagrams showing what you are looking for.  The manuals and books give step-by-step instructions.   You can visit the Repair Manual page for online repair information. 



Question:   1995 Infiniti J30 VG 30DE mileage: 39,500.  After reading your answers regarding battery drain, it certainly seems feasible that this is certainly the problem I am having with my J30.  I have had the car towed to the dealer at least three times and he assures me that they have checked everything they can.  They recharged the battery and after a period of a month and a half, it starts all over again.  I picked it up again today and the report read--after charging battery completely performed extensive tests on charging and starting system.  Found no draw in system and found no reason for battery to go dead at this time.  Cannot recommend any repairs at this time.  The first time it was brought in they replaced the control unit--hybrid.  Well, it certainly did not solve the problem.  I would appreciate any help you could possibly provide.

  Answer:    After reading your question and discussing it, we feel your battery may be faulty.  A load-test of the battery may or may not determine that your battery is defective.  If it fails the load test it is obviously your battery and if it load test okay, it still may be the battery.  The reason for this is that an internal short may or may not show up with a load test.
