Intermitent Coolant Leak

[gunnersfan10]

Ok So I'm looking for some advice or if anyone else has experienced this problem.

My boxster has a coolent leak but only on days where the temp. is 92+. I've changed the resoivor cap and topped the coolant level off about a week ago(when it was a little cooler but I live in chicago and now we are back into the 95+ range). it seemed fine until I found a few drops under the car yesterday but after an hour of looking i couldnt get it do leak anymore, so i drove it to work this morning with no issues. As i was walking out to start it tonight to run some errands I found a sizable puddle....Anyone have anything similar to this? Could it be a faulty hose or a crack in the coolant tank?


Any feedback would be greatly appreciated thanks
