My rx8 is leaking coolant from over flow hose. how do i prevent that from happening?
i dont over fill it. and i have also changed the cap.

 

If your not overfilling it, then how come its leaking from the overflow hose? Is the hose cracked or something...?

 

How old is the radiator? Which end is it leaking from? Hopefully not from that little tube off the top of the radiator.

 

If you drive hard or autocross you cannot. Even the dealer tends to slightly over fill the thing. It will spit. The only solution is to extend the hose to the belly pan and forget about it. This will also save your electric power steering from failing as that's what it drips on.

 

Is the car overheating?
