Symptoms of a Bad Radiator Cap: air enters the system, low coolant level, coolant leaks, overflowing reservoir, overheating engine.Once you have a replacement and your engine is cool, simply unscrew the old cap, and install the new by screwing it on.Professional, high quality style and meet or exceed all equipment performance replacement radiator cap. Constructed with premium materials for durability. Designed to function on open cooling systems and overflow reservoir type systems and allows the cap to be installed and removed much easier.REPLACES PART #: 16401-20353 16401-31650Manufacturer Part Number: 16401-31650COMPATIBLE WITH for VEHICLES: for 2003-2010 4Runner2003-2009 4Runner 4.0L V62010 4Runner 2.7L L42007-2010 Cruiser2005-2009 2006 GS3002007-2011 GS350 \/ GS450h2010-2011 GX4602003-2009 GX4702006-2012 IS250 \/ IS350Material: Metalcolour: As ShownPackage Contents: 10 x Radiator CapOnly the above package content, other products are not included.Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing.
