 |
|
HI, I recently did a check of my control pressure on my 81 931. The results were within spec, but it too about 20 minutes for the control pressure to reach 3.6 bar. The conditions during the test were about 52 degrees. The car achieved operation temperature well before the pressure reached that range. The fan cycled a few times before the 3.6 level was met.
How long should it take to cycle from low to high control pressure on the car? |

| Few minutes. Not 20. Check the electrical portion of your regulator. |
