How To Change Thermometers?

Do you want to change your thermometer on your own? Then have a look at the steps of changing the thermometer below:

Step 1 - Materials & Tools:

  • digital thermometer (3$)
  • piece of plastic from the junk (also paper or cardboard would also work perfectly)
  • Your dash panel

Step 2 - Choose the Place for the Display:

  • The display of the thermometer measures 4,5cm x 2,6cm so there would be a n need to find some cool place where I could put it.
  • You can find 4 possible places
  • one at the left of your steering wheel (occupied by the lights direction switch)
  • one at the right of your steering wheel (occupied by the car lighter)
  • one under the fuel level indicator, and one at the right of some car functions buttons.

Step 3 - Remove the Dash Panel and Prepare the Thermometer:

  • Then the dash panel should be removed with the help of a cutter. This is because it can be attached to some silicone. You can also use a screwdriver and then remove the panel carefully.
  • Suggestion: There is no need to worry if some piece gets broken by mistake, all you have to do is to buy it online or you can also go to the local store and ask for it.
  • Then the batteries should be inserted in the thermometer and then it should be compared with another thermometer to see it would work right!

Step 4 - Make a Stencil to Test the Hole Dimension:

  • You can also make a stencil with the hole of the same measures if your thermometer.
  • Now once you have drawn a rectangle on a piece of plastic, then you cut it and then try to insert the thermometer.
  • Now if the hole would be too small, then file it and re-test again.
  • When the hole would be perfect, then you should use your stencil and with a marking pen you can draw the lines on your dash panel.

Step 5 - Cut, File, Sand and Glue It:

  • Now once the rectangle has been drawn, then you should use your dremel and then cut following the lines.
  • Then you should try to insert the thermometer. If the hole would be too tight, re-file it and check again.
  • When the hole would be perfect then you should sand the surface to make all more perfect and cool.
  • Then the thermometer should be inserted in the panel hole for the last time and apply the glue.

Step 6 - Remove the Dashboard And...FIND MONEY:

  • If you want to insert the thermometer, then you should remove the dashboard first.
  • Take off all the switch caps by using a screwdriver and then you can remove all the screws.
  • After that the air diffuser should be removed and then once the fastens have been removed, then find the pre-existing hole with all the car wiring.

Step 7 - Insert It in Your Dashboard:

  • Then you should let the thermometer's wire pass through the dashboard hole and the wiring hole.
  • Then you should insert the wire through the dashboard hole.
  • After that, insert the "nylon probe puller" through the wiring hole and let it exit from the hole at the bottom-right. There would be a gap which would start at the right of the dashboard and then finishes at the bottom of it.
  • Then a piece of scotch should be taken and then wrap the thermometer's sensor so you can pull the nylon probe's end and let the wire pass through that small hole till the bottom of the dashboard.
  • The scotch should be removed and then re-insert the air diffuser.
  • Then the dashboard should be remounted, the plastic knobs, the fastons, the screws and then you should go to the next step to secure the temperature sensor.

Step 8 - Secure the Display in Place:

  • A lot of attack should be applied both on the dashboard and on the dash panel.
  • Just like it was done with the sensor, attach a piece of scotch to keep the dash panel in place while it dries.

Step 9 - Secure the Sensor in Place:

  • The wire should let pass to the left and a small quantity of silicone should be applied.
  • The sensor should then be pressed on the silicone and attach a piece of scotch to keep it in place until it dries.

Step 10 - UPDATE Place the Sensor Out of the Car:

  • Then the sensor should be placed out of the car. Then repeat removing the dashboard and make a hole on the left side, and then in the other the sensor should be allowed to pass through it.

TIP: If you do not have any power tools, then you should make a hole with the heated screwdriver. It would be a quick as well as useful solution; the result would be very clean.

Step 11 - UPDATE Secure the Display, the Wire and the Sensor:

  • Then the dashboard should be finally remounted, and then replace the plastic knobs and all the screws.
  • Then the display should be glued in place, and then it should be secured with wire glue and insulated tape.
  • The sensor should then be placed on the left door's hinge, and then again you should use glue and insulated tape.

NOTE: You would be able to set the wire in this way if you have an old car which will have wide gap all around the doors.
