Temp Light Flashing Please help

Recommended Posts

Yesterday I had my coolant expansion tank replace, after driving it away from the shop the temp light began blinking slowly (which usually indicates low coolant or engine compartment fan faulty) I checked the coolant level and it was fine, today I ran the car and let it sit running for a while and never heard the familiar noise of the engine fan coming on, what could have happend to the car during the installation to have this problem? I would like to have something to say to the mechanic when I bring the car back. Thank you for any insight on this problem.

Four functions of the coolant warning light:

1. Engine coolant level too low

— light flashes slowly (0.5 Hz)

2. Engine compartment temperature too high

— light flashes slowly (0.5 Hz) (engine compartment blower might be faulty)

3. Engine coolant temperature too high

— light is lit; pointer on the right

4. Temperature sensor at water outlet faulty

— light flashes rapidly (1 Hz); pointer on the right

Note

The temperature warning in point three is indicated if the conditions "engine coolant temperature too high" and "engine coolant level too low" are present simultaneously 

(1Hz = 1 flash per second.  0.5Hz = 2 seconds per flash)

Maybe the tech forgot to plug back the coolant level sender or it's not electrically connected.

Lift the bale wire and drive it a while.

 

The photo shows the bale wire down.  Place it straight up.

      Hi all,
      I have noticed that after my last service at the dealer the engine runs about 8 degrees warmer (about 220f) and the rear fan runs for extended periods after I shut the engine off. The oil pressure also seems to be lower than it was before the service, which included oil change, coolant flush, and coolant replacement. Any ideas on why this might be happening would be greatly appreciated. Thanks in advance.

      Recently I had been noticing issues with my cooling system the coolant temp guage would go past the 0 on 180 and I wouldn’t hear fans or anything. (Already tested fans and resistors and relays).   The temperature Will continue to creep up if I sit still, with no signs of fans, AC OFF.

      I replaced the coolant temp sensor. Problem fixed!! Then same issue again it seems after a week of driving.  

      Now i currently have ordered another temp sensor just Incase I maybe did something to cause the other new one too fail, I’ll be changing it again today.

      However I was doing the climate control hack to check my actual temperatures today while doing a short troubleshooting drive. And I noticed my oil temperature said 0, which is physically impossible 🙄


      Is it possible the oil temp guage is throwing off the coolant sensor?    Is it even possible for the oil temp sensor too go bad but not the oil level sensor? (They are a 2 in 1 sensor)   

      THANK YOU IN ADVANCE

      List Mates, I have a 2002 996 c4. When my Air conditioner compressor is activated the volume of air coming out of the vents is decreased dramatically.  It still blows cold but just very very low volume or amount. I have had it recharged , checked leaks , replaced condensors etc but nothing changes. As soon as you switch the ac off ( snowflake button) the volume of air through the vents goes right back up.  Volume of air is fine on heat , defrost etc.  I have never had this issue with any other vehicle. Any ideas as to what the problem may be?

      Hello All,
      The car has been awesome 2006 987.1 30k miles. The other day i took it for a drive and stopped after about 150 miles for about 30miins when I came out, all my coolant was on the floor. I refilled the coolant and constantly checked the temperature, initially it edged up to 180F but then settled back down to 175F and stayed that way all the way home. I was driving gently and kept cheeking the coolant level. Since then I found that I needed to open the coolant needle valve and drive around for 3 or 4 days to bleed the cooling system. I'm on day 2 and the coolant level has gone down slightly. Whenever I stop I check the floor and there has been no coolant leak.
      I am baffled, anyone seen this before?
      Thanks.

      Well I was driving yesterday when the coolant light began to flash, temp hit 200, so I went home and filled the coolant, which was really low. When looking through the fill, there wasn't any coolant all the way down. I put in about 3 quarts [ capacity 2.5 gal.] which was a lot of loss. But There wasn't any leaking. [?] The level stayed steady at the 1/2 min-max mark.
       
      Driving today, about 10 miles back and forth, not only did the light come on but the temperature shot up. I pulled into the driveway just as it hit 250. 
      No check engine light, no other diagnostic light, just the flashing coolant light.
      [meter/check codes?]
       
      When I got out of the car, I could hear a loud whine from the trunk. 
      Opened it to find that the coolant cap was venting hot coolant steam, and of course the loud and unnerving hissing-whine, from the cap.
      After a few moments it stopped. Waited till it all cooled down and slowly and carefully removed the cap. Same issue as above.
      No visible coolant in fill. I again put about 2 quarts, level hit between min-max.
      No leaks under car, coolant level hold steady.
       
      The mix is  1 gal. Porsche coolant [bought though Pelican], and 1 gal. distilled water.
      Shaken, not stirred to mix. Let sit. Yes, nice and pink when poured.
      The coolant tank is brand new, perhaps has a thousand miles on it. Cap came with the tank. Porsche, not OEM. Put on by a reputable shop which specializes in German cars. I screwed that cap down properly, real tight.
       
      No overflow. No leaks.  I'm loosing coolant when driving, only.
      Any ideas?
       
      Obviously I can't drive it. Next steps is to load it on a flatbed, and drop it off at the shop.
      {Poor Boxie} ?
       
      Thanks, as always!
