    1999 911 c4
  1. Here is my situation... 1999 Porsche 911 C4 I went to the race-track and overheated the car... after that when I started the car when it is cold the temp pointer is pinned to the right and the light blinks slowly, but after a little bit of driving the temp pointer reads temp accurately and light turned off. After completing the following "fixes" when I start car cold the light blinks and the temp pointer is to the right, but after a little bit of driving the temp pointer reads temp accurately but now the light stays on. If I start the car warm the only thing that happens is the light blinks slowly. To fix the initial issue I did the following: Replaced the coolant tank, Replaced the reservoir CAP with the black one Replaced the coolant level sensor Replaced the Engine Coolant Temperature Sensor I also tested the engine compartment blower and it works fine. My only guess is that the wiring on the coolant level sensor is broken. When I replaced the tank I noticed the old one was not mounted in the car and was able to flop around. Any ideas? Thanks Mark
