Strange leak
Hi All,
I seem to have develop a very strange leak on my TJ. I didn't drive it
since Sunday. Everything was fine, except for in the evening yesterday I
noticed a puddle of something just under where the radiator would in the
centre. I checked the consistency, its not oil and does not have any smell
(definitely does not smell like the coolant). I looked around with a light
and noticed some wet area around where the top radiator hose is clamped to
the radiator and around the seam area just around there. The water, or
whatever it is, seems to just dripped along the inside of the fan shroud
and then drip on the floor at the bottom of the shroud.
I drove it for a few kilometres to test, but the TJ never overheated or
noticed drop in coolant level. I then parked it in a different location,
nothing dripped all night or in the morning. I did not drive it today
during the day, nothing dripped till something like 5 pm. I noticed that
there was a small puddle again, same area wet. Drove it for around 10 kms
to push my luck and test, everything worked fine. There is no drop in
coolant or any other oil level. The liquid has no smell and feels like
water. Could this simply be condensation towards late afternoon, early
evening? But I had never ever noticed this before.
The funny thing is that the spot where the liquid had leaked yesterday
still has a dry mark on the driveway, so it could not have simply been
water (driveway is stained - water doesn't stain concrete).
I am stumped here, any suggestions. I have not tried driving on the
motorway to test any leakage at high speed. Should I try to get the
radiator pressure tested at a shop to see what happens? Is there any
easier way of testing this theory?

Re: Strange leak
'01 should have the extended life coolant which is amber colored, not green
like the old glycol. Does it taste like coolant?

Re: Strange leak
Well - it could be the radiator going - it's plastic in many parts and is
known to develop leaks - ours leaked in the seams up top about 1.5 years
ago. Through in some radiator gook to stop the leaks, and then bought an
all metal radiator - change out is quite easy on the TJ.

known to develop leaks - ours leaked in the seams up top about 1.5 years
ago. Through in some radiator gook to stop the leaks, and then bought an
all metal radiator - change out is quite easy on the TJ.
This site has a good write up I used....

Re: Strange leak
I recently helped a gent change his TJ rad. It too was leaking in the
exact same spot, right under the hose. That crack seal lets go from
vibration it would seem.
The hose has the vibration of the engine in it that transfers to the top
of the rad and the rad falls apart. Great design. (If you sell parts)
