Product Description

Coolant reservoir tank cap for the Datsun 310 & 311 Roadsters

It will also work on the radiator of ANY Vintage Datsun or Nissan vehicles that uses the larger type cap

HOWEVER- due to no rubber seal on the outer ring on the underside the cap, if there is a coolant overflow into the tank, it may not suck all of the coolant back into the radiator after it cools down

Use extreme caution when using the button to release cooling system pressure- the same caution you would use when removing a radiator cap

Cap has the Nihon Radiator logo on one ear and A9 on the other ear

A9 = 0.9 kg/cm², which is 13 psi, which is 88 kPa, which is .88 Bar

Fitments (may fit other additional vehicle models and years)
