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?
