Since a routine LR service to check and top off fluids and perform an oil change about a month ago (coincidence?), I have had a steady leak in my coolant, approximately 6 oz/day. I took it to the dealer, who reported finding the leak in the "lower radiator hose" and "oil cooler" and replaced the hose (why didn't they do anything to the oil cooler itself?). However, the leak has remained, losing coolant at exactly the same rate.
When I refill the overflow tank with antifreeze and water, I notice that the coolant (pink due to the LR additive) is very gel-like. It becomes less so after I top off and run the engine for 30 seconds. It is as if the leak is only water, perhaps through the escape of steam/vapor. There is no indication of a leak on my garage floor or in the engine compartment. The vehicle exhaust does not look or smell funny.
Anyone have any thoughts? The overflow tank? The oil cooler itself?
Also, what is the little black "stick" (looks like a walkie-talkie antenna) slightly to the left of the overflow tank? Mine has a little cap on the top that spins, won't tighten and appears cracked and broken. Some sort of a bleeder valve?
