You said SMALL... that just means your watching your car , saw the first indications of the leak and have time to prepare your attack on the problem... of course it would be good to clean the wet area and keep checking to see if this was just a spill from filling the vessel... not likely... but just to give you peace of mind that you are going to attack an actual problem...when you do start to do it... if you have a digital camera please take lots of pics of the procedure for the FAQ pages.. Thanks, Greg
