This is the first time this has happened. Is it possible that it is just a bad radiator cap? What else can it be ? What do you suggest I do? There are no apparent leaks and my reservoir was basically full before my trip. Now, it was empty but remains full as I poured more into the reservoir. Only heats up as I press on the gas.
