Review on High-Quality Radiator Cap 19045-PAA-A01 19045PAAA01 for Honda Accord (1994-2006), Honda Civic (1992-2005), Honda CRV (1997-2005), Honda Odyssey (1995-2007), Honda Pilot (2003-2008) by Glenn Cho

For some reason my old radiator cap had an extra rubber gasket (see pics) but I don't think it was part of the original manufacturer assembly and that rubber gasket doesn't come with purchases. Not sure how it got there or if I need it, but checking some online diagrams tells me I don't need it (will update this review next time I visit a mechanic). Fits my 2005 Honda Accord V6. Metal seems cheaper so definitely not OEM but it fits. Installation isn't as smooth as I thought, you have to press a little harder and twist while pressing, then the metal tabs on the side have enough play to screw the cover in. The rest of the design is similar. and I don't think there will be too many questions. The time will show.
