The cluster in our vehicle gives us a ton of information we are constantly relying on when we are driving. Whether that is to know how much gas we have in the tank if we are speeding, or even if the car is overheating. Any issues with any part of the cluster can prove to be a challenge on the road and can result in unsafe driving. So if you notice any of them giving you trouble, like the speedometer giving you the incorrect speed, you should get a repair or calibration. When it comes to speedometers, you can tackle it on your own if you’d like or you can go to a professional like Safety Restore. Here is a quick how-to guide for speedometer repair.
If you have an electric speedometer you would start by determining the distance of the test drive you would need to recalibrate your speedometer, which can be found in the vehicles supporting documents. Press and hold the calibration button located on the speedometer, start the vehicle and then release the button. Press that button again and then take the test drive. Once you have driven the distance needed, press the button once more and the speedometer will calibrate itself to accommodate the new tire size.
If you have a mechanical speedometer, start by opening the vehicle’s hood and locate the transmission. Next, unscrew the speedometer cable and unscrew the bolt holding the gear housing cover. After removing the plate, you will see two gears. Count the number of teeth the gears have and remember it for later. Next, get the diameter of the tire and divide 20,168 by the tire’s diameter. This is the tire’s revolutions per mile. Multiply this by the number of teeth your gears have and multiply again by the vehicle’s axle ratio (which can be found in the vehicles supporting documents). Purchase the necessary driven gear for your vehicle. Remove the old driven gear by pulling it out of its clips and clip in the new driven gear. Secure the gear housing cover and the speedometer cable back.
