Mishimoto 1.3 Bar Rated Radiator Cap

Product Description

Getting the most out of your performance parts comes down to the details. When faced with hard driving conditions, a vehicle's cooling system becomes highly pressurized. OEM caps are not equipped to handle higher pressure, causing fluid to leak out into the overflow reservoir. The Mishimoto radiator cap is rated at a higher pressure and will keep coolant where it needs to be-flowing within the system. Rated at 1.3 Bar (19lbs) pressure. Fits most import vehicles.

  • Mishimoto Replacement Radiator Cap.
  • 1.3 Bar Pressure Tolerance.
  • Fits 31-32mm Fill Necks.

Great option

This won't help your bike from over heating but it will definitely prevent the bike from over heating easier and easier throughout the ride. Just as described by the prevents fluid from pouring out the overflow. If you are a big hill climber like me; you will experience an overheated engine quite often and the last thing you need is the fluid draining out to a dangerous level. This cap works really good and looks cool too.

Proper fit?
I have a 1984 VF700F and need a new cap, will this fit my particular bike.

This cap is made specifically for Mishimoto Radiators, it would likely not work correctly with your OEM Radiator on your 1984 Honda VF700F. I would recommend looking at the OEM diagrams for your bike for the original radiator cap for your bike. [ Honda OEM part # 19045-MZ3-405 ; CAP, RADIATOR ] [ OEM Link: ] (***Please note we do not have the diagrams for your 1984 model listed online but the radiator cap is the same as on the 1985 model that we do list the parts diagrams for online)
