I have a 2002 911tt x50 it has been in storage for the winter. I was able to finally get it out Friday. I noticed a coolant smell after some driving it. I checked the level it was fine I looked under the car nothing was wet. I got the car back to the garage and noticed coolant by both front tires. The coolant was cold so it was there before I took the car out. I checked under the car nothing wet. I drove the car to the dealer car ran fine perfect temp and again nothing wet, fluid level was fine. The car was in storage about 3 months. Any Ideas the dealer is chcking the car but the waiting is killing me. The dealer did say it may just be leaking from sitting and the fluxuation in temps. he felt it was nothing to worry about.

 

I had front left and right radiators replaced last summer. Saw coolant leaking in the front tire well area. Pressure test didn't reveal anything, but when the car got warm and I did spirited runs, the rads would expand and then leak. Definitely if you smell coolant, figure it out! Annoying. Replacing rads is expensive unless you do it yourself.

 

My car does the opposite and it did not leak after I drove it. my other 911 used to leak oil in the winter and once I started diving them again they would stop I hope this is a similar situation

 

Mine had a leak in the lower rad hose on the passenger side. Walked out of homedepo and saw a puddle and slightly dripping, drove it home and it stopped. Thought it possible swelled and shrank closed but it returned again two days later. Pulled the bumper and the lower rad hose had half slipped off. (it is held on with the same little metal bands that the boost hoses have) So I just slipped it back on and noticed that it was just barely long enough, so it wouldn't happen again I loosened the other end of the rad hose(this end uses rad hose clamps) and pulled more slack for the front so it was forcing it in place instead of it pulling on the metal band and the plastic housing. Hope this helped, it was an easy fix.

 

I just got the car back from the dealer. They had the car Friday-Monday Said it did not leak at all and had no signs of leaking. They said it was probably from sitting in storage. The guys at Knopf Porsche in Allentoen PA are great. They did not charge me and kept the car inside the whole time. This is not the first time they checked the car out for free.
