My Nissan pickup (2.4L) uses a stock 13 psi rad cap. Nismo makes a high-pressure (18 psi) cap for, well... any Nissan owner who cares to spend the money. According to Nissan:
The Nismo radiator cap is a heavy duty radiator cap, which operates at 18.2 lbs (1.3 kg/cm) compared to 12.6 lbs (0.9 kg/cm) non-turbo and 16.8 lbs. (1.2 kg/cm) turbo Nissan OE(Original Equipment) stock caps. Made for vehicles that need more cooling than the stock radiator cap provides.
Now, I would REALLY like to have more cooling than the stock rad cap provides. Our summers down here are brutal, and I haul some heavy loads. However, I would assume that the "more cooling" comes at a cost.
So, besides the increased possibility of blowing a hose, what are the other risks/downsides?
