Great Porsche story:

My 1987, 944 was leaking radiator water on and off for about 6 months.  The
other day, on the way to the NYC - about 100 miles from my home.  I noticed
the temp gauge pinned, but I had about 10 miles to get to the service area,
watching the gauge and praying.  The temp did go down a bit as I drove, so I
just kept going the 10 miles to a service stop.  Let her cool down a bit,
and filled her up and went on my merry way.

Then, a week ago I went camping - it was like the hottest day of the year
around here - in the 90's and humid.  Sunday and ready to leave and I
noticed smoke under the hood - no. it cant be me...it must be dust.  Oh
well, check the temp gauge, and the gauge was pinned again, but this time
the light was on in the temp gauge.  I didn't even know it had a light.

Blown hose - the hose that goes to the heater temp switch towards the back
of the engine.  There is no way I was getting stuck...but I had no tools and
it was so hot out!

Well I borrowed screwdrivers, pliers and a mini set of tools and would you
just know it, I was able to cut a section of 1 1/2 D or so hose from the
bottom of the coolant overflow container to the radiator - I replaced the
back hose with the cut out section and I drove the 200 miles home in ac
comfort!

When I got off the expressways and parkways, and was on the last final back
roads to my house, at the first traffic light, the gauge was pinned again.
I drove to the gas station, and would you believe I actually left the
radiator overflow cap off...for the entire 200 miles - the 944 ran cool...

I replaced the cap - it was just lying there next to the ac filter - and
filled her up again with water - and actually got home.  The hose repair was
an emergency but it was great and permanent...and 2 weeks later, no more
radiator leaks.

260,000 miles and running strong.  Porsche makes a great car - it so much
more than mere beauty or handling!  Sometimes over the years of ownership -
I swear the car can cool itself with just air.
