Oil Temperature Gauge Light Blinking

We don't have an oil temp gauge. Do you mean water temp? Blinking I think means add a little fluid/water.

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.

Hmm. Just had the same red flashing light immediately before a long journey (500 miles) on a very hot day with the car sat in bright sunlight.
Kept an eye on the oil temp, never seemed to go much above 80 (may have touched on 90) which I guess is acceptable for such a long journey. Light stays flahing now, even when I've let it the engine cool for a while, and immediately this would flag up to me 'low coolant level', which I will sort tomorrow.
Noe, on the subject of coolant, does it need to be 'special', as in my previous BMW, water would suffice, but I know thats not always the case with cars, indeed, maybe only limited to a few.....

By all means, consult your owner's manual.
