High pressure radiator cap/Radiator cap 1.65" - 1.3 bar
Many original radiator caps are not made to withstand high pressure from the coolant, which can cause leaks and unnecessary coolant spillage into the engine compartment.
That's why we have this radiator cover, which is manufactured to be able to withstand up to 1.3 bar pressure, and ensure that the liquid stays where it is intended. Namely in the system.
