  1. Keeping Cool

    Keeping the engine cool is one of the best ways to save fuel and get extra power. 1. Depending on your situation, replace the exhaust with a larger tube on the order of 5cm to 7cm diameter. This allows hot gas to exit faster carrying that waste heat away. 2. If you've got the cash, have the exhaust manifold ceramic coated. (or purchase a set of headers that have already been plasma coated.) That lowers underhood temperatures more than 60f. For every 30f drop in intake air temp you get an extra horse or two. Cooler is better and there are a million ways to slice a mango.
  2. Gas Filter

    There is a quick way to check the main gas filter and it only takes a second to do. Place your thumb on the input and your little finger on the output. If the input is hot and the output is cold, then the filter needs to be replaced. Buy the disconnect tool. Don't be cheap. Most cars use a circular tension retainer and it is so easy to break. Other cars have the filter at the engine compartment and the fuel line bolts on to the filter. There is also a little bitty filter at the neck of each injector that is fairly easy to replace. Lastly or firstly....there is the gas tank. It should be cleaned every couple of years, not only because of contaminants like water and such, but the sock filter at the bottom of the pump assembly gets hard and crusty (beyond normal DIY talent to replace).
  3. i10 engine oil suggestion

    The oil you use is dependent on the average ambient temperature. Check the owners manual. It will have a chart with various flavors of viscosity matched to ambient. 5-30 is used in colder climates. Synthetics have been discussed in other posts.
  4. The TDI is a good choice. Follow some simple rules to keep it trouble free. a. Idle down for a minute before shut down especially after a long hard ride. b. Keep the air and fuel filters clean. c. Follow the oil change routine. d. Have the tank cleaned every two years to keep the sludge and moisture out.
  5. Do I need to change my tires???

    You can change your tires anytime you want. A slightly wider tire will give a smoother ride. I had a set of Michelins and finally changed them at 100k and not for the wear. They had plenty of tread left but I was tired of them and the Michelin dealer gave me a generous trade in discount on a new set. I also purchased a new set of wheels to replace the stock rims (got a trade in discount on the rims too). They did the balance, alignment, suspension check and nitrogen so I was satisfied. Just want to emphasize that it was mostly a cosmetic decision. The warranty on the new tires is 160k with free balance, rotation and nitrogen for the life of the warranty.
  6. Convert any car into an automatic

    Why would anyone want to do this?
  7. Clutch/RPM Issue

    I should add a bit more. The only way that an engine can accelerate is if it has more air. Air is controlled by an air solenoid and they come in many shapes and sizes. There is also a plethora of vacuum tubes that can leak as well as gaskets in the plenum. You can also run a test with and without the a/c running as it also affects the IAC. Bottom line is to go to the dealer and get him to make that phone call.
  8. tripmeter error

    Which is it...the fuel pump assembly with a faulty sender or a bad gauge? That's easily checked. If it is indeed the fuel pump sender...(the pump and sender are separate you know) you might still have to replace the whole assembly.....and....if you have a lot of kilometers on the car then have them clean the gas tank and replace all the filters...both those in the tank and those outside of the tank. Sometimes...yes it is true....perhaps you just mashed the wire in the harness or got some dirt in the cable connector...don't let them jump on charging you for a pump assembly without diagnosing the problem correctly.
  9. Clutch/RPM Issue

    That's because he probably didn't read the tranny harness signals to the ECU....if there were any signals. On some cars you have to diagnose the tranny separatel. That means putting it on the lift while monitoring the signals both (input and output) at the tranny and the ECU. Diagnosing the on-board electronic system takes patience and skill. There is a lot of interaction designed to keep emissions to a minimum. For instance when you let up on the gas, the ECU controls the rpm's to burn any residual fuel so you'll notice the rpm drops a bit slower. There are other conditions both mechanical and electronic too numerous to mention and if the mechanic can't solve it the go to the service office and have them call the regional engineer. He covers a pretty large area and it is his job to stay current on the factory service bulletins and resolve the issue with your car. Please keep in mind that new cars with new technologies require an automotive engineer with mechanical and electronic skill sets. Quite an upgrade from 20 years ago. ....and they make good money. Many small shops can't afford a professional but most know a specialist they can; the regional engineer.
  10. One pair of sunglasses, neutral gray, are in the little drawer above the mirror. That way I always have a pair ready for the sun. I'm not sure about yellow lenses or blue lenses. There is some sense to wraparounds. The sunglasses are uv rated which I hope will cut down on the fatigue. I don't favor window film.
  11. Clutch/RPM Issue

    Go to a shop and have them diagnose the vehicle with the computer.
  12. AAA ( all about automatics)

    The most important thing to keep in mind when it comes to automatic transmissions is that they wear out and it is an expensive process to rebuild them....yes, rebuild. Whenever you open it up...even for a faulty have to get the super master kit and replace all the friction plates and other parts..etc.etc.etc. If you own a tranny shop, you make good money.
  13. Decarbonising

    There are products for getting the carbon out but they are not available in India. Remember also that if your bike is a two cycle the mixture runs through the crankcase. Using the wrong chemical at the wrong place will ruin the seals. Good Luck
  14. AC water - inside car

    The drain pipe could be fine and the problem is dirt in the airbox. Pull off the pipe and push a wire up there to see if you can flush it out if the pipe is ok.
  15. Maruti 800 Starting problem

    It's called a vapor most cases and is caused by a problem in the fuel delivery. It can also be caused by faulty ignition components so you have a lot to check.
  16. AC on/off query

    Yes you can cycle it on and off. New cars will cycle the compressor automatically.
  17. Steering Vibration

    sb-alto is right! I totally forgot to add that you must check your rims! Tire shops must follow factory protocol and use a calibrated torque wrench when mounting the rims. If not the rims will warp. Unfortunately, tire shops don't use a torque wrench. They just tighten the crap out of the bolts.
  18. Is Shell Petrol better than others?

    How old is the station where you gas up? Older stations collect a lot of contaminate such as water in the underground tanks which goes directly into your tank. Try switching to a newer gas station.
  19. Steering Vibration

    Flywheel I forgot one thing. Don't forget to check for cracks on support members such as the strut towers and the lower A assembly. Although not likely....rev the engine slowly through the operation range in neutral to ensure that it's not the engine vibrating.
  20. Steering Vibration

    Tires can be sold as "blems" which means blemished...or what we call "#2s". These are the tires that don't meet exact specifications but can still be sold. A tire store can check them.\ If the tires balance off the car (assuming they were balanced correctly) but you have vibration when on the car have the tire store balance the tires while on the car. That is called dynamic balancing. Otherwise, check the entire suspension system including the rack and pinion. Remember that vibrations don't get better...they just get worse and could cause an accident.
  21. Steering Vibration

    Check wheel bearings. Do a dynamic the tires while on the vehicle. Did you check the engine and body mounts, tie rod ends and the complete steering assembly? Are the tires first quality or blems? Make sure to check
  22. turbo and intercooler cleaning

    Turbos need clean air so keep that filter clean! There are several ways to keep up with turbo aging although they are a bit more technically involved. The first is to install an EGT meter. I can't stress how important it is to know your environment and driving habits to avoid an over-temp condition at the exhaust. When the engine is cold you can pull off the turbo and feel the turbine blade tips. If they are rounding tor deformed, you've exceeded temp. Spin the turbine blades with your finger ever-so-slowly to ensure that rotation is smooth through 360 degrees. If you feel the slightest pause then the shaft or bearings are gone. There are kits to rebuild turbos. I inject a minute amount of UV dye to spot hairline fractures in the exhaust manifold and turbo housing. This also allows you to spot leaks on the pressure side of the intake. Having a boost gauge will help keep the pop-off calibration honest. Use a digital IR thermometer to keep check on the input/output differential. Make sure to chart mixture vs rpm throughout the range. Once again we're getting a bit techie here. Remember that it is the mixture that destroys turbos. Last, but not absolute, make sure to check for down-line exhaust restrictions. If you are a motor head, we can wire up the computer and run diagnostics and calibration....but that is mostly for enthusiasts, racing and research.
  23. tire pressure measurement problems.crazy

    Sham buy a better tool.
  24. Which car wax is best for new cars...

    As I stated in an other post, waxes are obsolete. Newer products keep the shine for well over a year and are superior to waxes in every way.
