Oil Temperature Gauge Light Blinking

Blinking might also mean that the fan is not coming on. Check your owner's manual.

I think I heard the fan kick on and off a few times, when I was sitting in line at the bank with the windows down......

Do I add just straight water or does it need to be a mix of coolant and water?

Well, check you overflow container. Is it leaking? Pull up the carpet and look there too. If you add just water, it needs to be distilled water. You are OK to add just water if it only needs to be topped-off. If more is required, you need to add a mixture of water and coolant. You need to use the correct coolant too. Do a search for coolant.

I just went to check my car and there is a pool of engine coolant on the ground underneath my car.

Sounds like the coolant tank crack deal. I had the same thing happen. I would first top off the coolant with the proper mixture. If this turns the blinking light out, that is a good thing it may be just low. Considering you have a puddle of coolant, I am leaning more towards the tank needing replacement.

This will set you back about 700 to 800 bucks with parts and labor.

Best of luck!

It could just be a hose clamp. Porsche used really crappy plastic ones and they become brittle over time.

The overflow tank crack usually puts some coolant in the rear trunk under the decking too.

I hope it's just a hose clamp or a hose. MUCH cheaper.

Wow, a flashing oil temp idiot light means low coolant level? That's a new one I have to put in my troubleshooting notes. If the coolant was low, in this case leaking and not allowing the coolant system to pressurize, the water temp would be above normal also. If the oil temp light was accurate I would say; 1. Check the oil level. 2. Check the electric connection at the temp sensor. 3. Check if the oil temp is actually high when the lights on (diagnostics). 4. Insure the oil cooler has coolant running through it (this might be where your coolant leak is coming from).

Please keep us informed as to the fix.

I just reread your post, you said " I noticed a little red light blinking on my dash board on the oil temperature gauge". I went out and looked at my car, are you talking about the coolant light blinking? That's water temp not oil. I believe the light is for overheat and if the gauge is reading fine it must be the sending unit for the light.
