Brand new and never used parts. Made of high-quality materials that meet OE standards.
It is extremely important to always make sure to allow the engine to cool down before removing the radiator cap, as removing the cap from a hot system can cause sudden coolant spray and severe burns. A faulty radiator cap can have a huge impact on the cooling performance of your vehicle, once you have a replacement and your engine is cool, simply unscrew the old cap, and install the new by screwing it on.

Features

REPLACEMENT RADIATOR CAP : The radiator cap holds the coolant inside the radiator, but it also works as a two-way valve that keeps the right pressure inside so the radiator does it work correctly. If the pressure isn't maintained, the coolant can boil and evaporate, putting the engine at risk of overheating. Symptoms of a Bad Radiator Cap: air enters the system, low coolant level, coolant leaks, overflowing reservoir, overheating engine.
COMPATIBLE WITH TOYOTA, SCION VEHICLES : 2009-2016 4Runner | 2009-2012 Avalon | 2002-2006, 2009-2012 Camry | 2009-2014 FJ Cruiser | 2008-2013 Highlander | 2008-2017 Sequoia | 2007-2016 Sienna | 2008 Solara | 2009-2016 Tacoma | 2010-2017 Tundra | 2009-2013 Venza | 2009-2014 Yaris | 2012-2015 Scion iQ | 2009-2012 Scion xD radiator cap.
