Adam, A properly rated and funtioning radiator cap is critical to the function of an automotive cooling system. If the pressure rating is too low, the water/coolant mix will boil at a lower temperature and the engine will heat. A higher pressure cap will let the coolant reach a higher temperature without boiling, but if this is over the design specs it may cause leaks or sudden failure (i.e., a burst hose). The correct coolant bottle cap (14 PSI, I believe) from your Favorite Delorean Vendor is about 5 dollars. As for gas caps, I recommend the delorean.com replacement. It is a perfect look and fit. Ten bucks. Gus Schlachter Austin, TX VIN# 4695 "Adam " wrote: > I recently got a new radiator cap and installed it. It is rated at 16 > lbs, and I am curious if this could cause any sort of problems.
