I started to get the low coolant! light every now and then when I jump on the gas.

So does coolant magically disappear or get used up or is this leading to another issue like the dreaded coolant pipes. I don't remember seeing any leaks. I guess I should look and see what the oil looks like and if there is any mixing.

I also have a re-man'd engine. I can't imaged Porsche would give me another bad motor, or a motor with plastic coolant tubes.

How exactly would you like me to break this to you ?

Have you used the procedure at the top of the forum to determine which type of coolant tubes you have?

I was just looking at that again. I guess once you get a mirror and a light under there you can see if they are plastic or metal.

so I take it the coolant shouldn't go anywhere unless there is a leak.

Its not unusual to have to top off the coolant bottle after a few years -- some of the coolant level sensors go off when it is just a little down.

But the coolant went someplace -- sometimes the caps can vent it.

It is obviously low enough that when you accelerate the fluid moves around enough to set off the sensor -- I would add some to see how low it really is.

Mine went off after about three years -- It was not very low. About a year later (this past summer) I started to smell coolant even though I could not see any drop in the tank. They first replaced the water pump -- then the thermostat and a few "o" rings - finally the coolant pipes.

Good luck

Yes, and in Cayennes, we know where it goes.

I would definitely figure it out ASAP before additional damage is done once the floodgates open.
The good news is it might just be the coolant tubes ... the bad news is it might be the head gasket (engine replacement).

On my 6er it tends to go away all on its own ...

Maybe he is lucky and it's only a bad seal on the tank cap ...

coolant light came on when mine was 2 qts low. not a little in my book.

My sensor was quick to go off -- the tank looked full. Were not talking 2 quarts -- I'm talking less than a 8-oz.

Who knows if the system was filled all the way when they changed the engine.

Mine is going back this afternoon to install a bunch of previously ordered interior parts and to check on the fluid levels after all the work that was done on it this summer. Unfortunately -- from what I understand they put the plastic pipes back on the replacement engines.

Would be interesting to know the percentage of cars with failed pipes. I do not know if my pipes ever failed but they replaced everything -- including all the hoses and the clamps

It could also be the coolant expansion tank that's leaking- I had that replaced. My coolant pipes were replaced under warranty. Mike
