Hot day...100+

[Granitehead]

I pulled into the driveway after work today, went in the house, came out and there's antifreeze all over the driveway. The low coolant warning light is on too.

Any thoughts? Are there hoses that are prone to blow?

The car's a 2002 Boxster S with 52K miles.

coolant tank

I forgot to mention, it's coming out of the rear of the car. Is that where the coolant tank is located?

rear trunk.

check the carpet see if it's wet. check around the cap, pull off the plastic holder. pull up the carpet, see if there's coolant in there.

It was wet around the cap. The carpet's dry, but it was really warm back there so maybe it dried out by now?

I put some water in, started it up, and it's not dripping anywhere.

I don't know...this can't be a good thing. Lots of people probably drive Boxsters in extreme heat without the car boiling over.

It could be just a hose or hose clamp or the crappy overflow tank caps Porsche put on our cars from the factory. However, it's common on our cars for the coolant overflow tank to crack with age.

Everything but the cap is hard to see and get to. You probably need to get it towed to a porsche mechanic for closer examination.

Granitehead,

I bought a 2002 base model with 34K miles just last May. A few weeks later while driving down the freeway on a very hot Texas day, I had an engine light come on. I didn't hear anything unusual and did not see a change in the engine temp, but got off the freeway at the next exit. I shut off the engine at the stop light and restarted it after about a minute. The engine light went out and stayed out for about half a mile, then came on again and the temp started to rise slightly. I pulled over immediately and shut it down. Thirty seconds later, about half a gallon of coolant spilled out on the ground, near my right rear wheel.

I had the car towed to a Porsche dealership. After a complete diagnostic checkup, they said everything was normal, no leaks, and good coolant pressure. They thought that the non-Porsche dealer that serviced the car before I bought it had allowed air into the coolant system and that it may have caused it to boil over and dump out the overflow. This is my first Porsche and I don't know enough to say for sure that it could cause an overflow. I have never had another incident even though it has been very hot here in Houston. The total cost at the Porsche dealership was only $179. So maybe something similar happened to you. Good luck!
