Coolant leak Help!
Okay, so I recently installed a built D16Z6 into my hatch, I used the stock D16Z6 radiator which is a year or so old. I'm losing coolant and I can't see where. I don't think there is a head gasket leak because there are no bubbles in the coolant, the oil looks fine, and there is no white smoke coming from the exhaust pipe. And as far as I can tell, there are no noticable leaks. If the cap is bad how do you know? Does it release coolant? Is there some type of leak test I can have done on the cooling system? Thanks guys.
