As title states, I have a small coolant leak. And I have to add on about every 2 weeks cause it pops up on my dash check coolant level.. looks like it's coming from the top drivers side radiator. All I see is the dry coolant don't know where really. Think maybe a o-ring in the upper top radiator hose. At first I thought it was the radiator drain plug but then I looked above. I might just buy the upper hose and drain plug and change it out. Anyone experience this before? The car has never overheated or shot up. Temperatures are perfect.
