When the ecu of my 1994 Volvo 850 Turbo was showing some bad readings about the knock sensors, I picked and pulled the old ecu and got a new ecu from a 1993 volvo 850 non turbo. Is it possible for an ECU from a turbo car to replace ecu from a non turbo car? Thanks.

How can I replace the Serpentine  Belt on my 1997 Toyota Camry 2.2 L 4 Cylinder?

Answer: Toyota Camry equipped with power steering has two belts. One that operates between the crankshaft pulley and power steering pump. The other is drive belt that operates from the crankshaft pulley to the alternator and air conditioning compressor. To replace the large diameter belt that drives the alternator, you have to remove the plastic shield in front of the crankshaft pulley (held in place by two 10mm bolts). The pivot bolt on top of the alternator is loosened (14mm), the bolt that secures the front ear of the alternator (12mm) is slackened and then a long threaded adjusting bolt (12mm) is turned to loosen the drive belt so it can be removed and replaced. It is more difficult to replace the power steering belt since it is accessed from the bottom of the car so the car must be jacked up and supported by axle stands. A bolt on the power steering pump adjusting bracket and the pivot bolt for the power steering pump must be slackened to enable the power steering belt to be replaced. After replacing the fan belts assemble in reverse order. Ensure fan belts are properly tensioned and aligned. Start the engine and allow to run for a minute. Re check alignment and drivebelt tension. Turn on air conditioning, headlights, heated rear windscreen and start the engine, turn the steering wheel form side to side, if belts are properly tensioned the belts should not “squeal”. If belt “squeal” is heard the fan belts are improperly tensioned or aligned.

How to fix the rear mirror on 1996 Audi A4 Avant, just yesterday  the internal rear mirror came away from the glass! I don’t know how to fix it since the surface that came away from the glass is just a smooth disc and only a round mark is left on the windscreen. Can anyone help?

Answer: The round mark on the glass is the glue that held it on there. Go to an auto parts store and get a kit to glue the metal piece back to the glass. Get some masking tape and put a piece on the windshield where the bottom of the metal piece is supposed to be, also put a piece to mark the location of one side of the metal piece. Then take a razor blade and gently scrape the remaining glue from the glass so you can put the mirror back to where it’s supposed to be. Remove the metal piece from the mirror, the mirror usually slides on the metal piece from the top and has a screw to keep it tight. Follow the directions on the package to clean the glass and the metal piece, then apply the glue and line the metal piece up with your tape marks. Make sure that you glue the right side of the metal piece to the glass! Use another piece of tape to hold the metal piece in place while the glue dries, it will take longer than a minute. The package will say how long to wait before putting the mirror back on.

My tail lights don't light up when i turn my head lights on although the head lights are ok. My corner lights also don't light up. Does anyone know the possible problem? Thanks..

Answer: Well, you can start checking the fuses...

Answer: I don't think lubricating serpentine belt causes this. Maybe your fuel pump is not delivering enough fuel. You say that the problem occurs after lubricating the belt, do you notice that belt slipping?. Sometimes the oil or spray can get in to a sensor and make it acting weird. have you tried to push the gas pedal to keep the engine running?, how long has been doing this? before or after the serpentine belt has been lubricated?. however, the serpentine belt don't need to be lubricated.   

Response: Yes I have tried to keep the engine running by pushing the gas pedal, but as soon as I took my foot off the pedal the car stopped. According to the mechanic, the belt gets dry and was lubricated with all purpose belt dressing spray that could be used on all serpentine belts.

*My 2003 Toyota Camry is doing the same thing except the check engine light comes on when the car cuts off. my car also stays on if I push the gas pedal. Sometimes I need to do this 2 - 3 times before the car stays started, no one can figure out what the problem is...

The following diagram / schematic depicts the 2000 Buick Regal ABS / Antilock Brake System System diagram.

The transmission on my car, the 1991 Ford Explorer suddenly lose reverse and start leaking fluid out the over flow tube, It was -15 degrees that day. Does anyone know about this? Thanks.

Answer: Overheating of the transmission fluid will cause it to expand and be pushed out of the overflow tube. If the transmission slips, it can cause the transmission to overheat and heat the fluid. If the transmission was a bit overfull to start with that will worsen the problem. The loss of reverse may have caused the transmission to slip and the fluid to overheat. No mater what the outside temperature is a slipping transmission can overheat the internal fluid. You should also check the transmission fluid cooler for proper operation.

Where is the location of the fuel filter on a 2000 Chevrolet Cavalier? I think the fuel line is on the driver side but, where is the filter,? after googling it, I found the location is under the frame, but, still, I can’t find it. Is there any good diagram / schematic I could use? Thanks in advance.

Answer: The location should be in front of the left rear tire, below the frame. Juck your car up and you should find the fuel filter laying up against the bottom frame of the car with one quarter inch stainless tubing going in at one side from the rear forward and out the other side. You can pull it down after screwing some tubing clamps to give you enough space to take it off.

I Just bought the newest version of the navigation system for my 2008 Nissan Maxima, but I can’t locate the DVD ROM drive, where or how to install the disc? Thanks.

Answer: It is quite hidden isn’t it. The location of the DVD is in that compartment under the radio, open the door and remove the inside insert. You should find the DVD player behind the insert. Eject the old mapping soft ware. Follow instruction you got with the new Diskât

im trying to replace the fuel pump on my 2001 BMW 330Ci, Does anyone know how to loosen the ring that holds the pump to the tank, the one on top of the fuel tank? Is it the right way to hit the indentations on the ring, to make the ring turn, I have to make sure before I hit something. Do you have links for this question?

Answer: The right way is by using a special tool that has several lugs that fit into the indentations of the big ring/nut. But if you don’t have one, you can hit the indentations on the ring but, use wood or plastic piece on the indents and hit from behind with a (preferably, a non metallic) mallet.
