Just got 350 couple months ago, seen that their is a upgrade to the cooling system (expansion tank) my car is an 04 would i be advised to have this upgrade and what can i expect to pay?
wouldn't bother if its behaving itself, mine is fine without, on a run temp is about 89 and in traffic it controls at 90 - 94. I think I have read somewhere that it is a fairly cheap mod though.
