If you have suspicions of excess temperature’s in your power steering system there is a great little device available to give an indication of maximum temperatures attained over a period. Thermindex make a temperature sensitive adhesive label that consist of a series of silver dots that will change to black as their pre determined temperature is reached. Simply apply one of these inexpensive labels to your power steering reservoir , after making sure that the surface is clean and smooth.
Run the vehicle for a week or two and check for the maximum temperature achieved. If the label does not make firm uniform contact the results will be inaccurate. Of course there are many other uses for these great little tell tales, engine sumps , diff housings , transmissions , alternators just to name a few. The strips are available in temperature rangers so two stickers may be required if you have no idea of what temperature to expect.
Remember power steering systems that over heat generally mean there is a problem and you should contact one of our Hydrosteer branches for support.
