Just wondering if anyone out there is using the Dali coolant Tank and if you have had any coolant leaking from the overflow hose. I have had the Tank now for three years and never had a problem what so ever even with tracking the car. Now this year I noticed a small trickle of coolant coming from the rear overflow hose everytime I drive the car. I went out a bought a new cap played with the level of coolant etc and still I get a trickle any ideas out there what might be going on.
