I am currently going thru the archives, but havent found what i need to know yet. Last night when I arrived at home, I noticed a *hissing sound comming from the front of the car. Not the tire so I will have to think it is comming from the cooling system....I will of course try to get this checked out ASAP. My question is how much coolant should I see when I look into the "header" bottle located in the engine compartment. The original one has been replaced with the stainless steel model and when I looked inside there was barely any visible. Should I go ahead and add some....and can you add just water or do i need to add a 50%-50% mix of water/antifreeze. Oh the engine temp is normal.. Thanks guys... ===== C VIN 16367 __________________________________________________ Do You Yahoo!? Bid and sell for free at http://auctions.yahoo.com
