## Features

- TOP QUALITY/ GUARANTEED
- It may seem insignificant but the radiator cap plays an important role in the operation of the vehicle. This part retains different amounts of pressure that are generated by the antifreeze flow and its temperature. If the cap fails to handle the pressure, it could cause damage to cooling system components and may even cause coolant evaporation.
- Antifreeze leaks, white residue in the radiator, an overflowing reservoir or a collapsed radiator hose are possible signs that the radiator cap is failing. If your mechanic confirms the failures of these parts you should replace them AT ONCE to avoid downtime of your car.

## Questions & Answers

**Q: The radiator cap is not a pressure cap. is this a pressure cap? the coolant tank is a pressure cap**
A: The radiator cap has a spring and rubber seal that keeps your radiator at 88kPa or about 13 PSI. So technically yes it is a pressure cap. This is why during coolant replacement service or checking for leaks the cap should be checked and/or replaced.

**Q: Will this cap fit a 2016 Nissan Rogue?**
A: I don't know, but my car is 2009 Nissan Murano.

**Q: Will this fit 2008 ford explorer v8(4.6l)?**
A: It was for my Nissan Murano, so I am going to say, no. If you have a Ford with a v8, 4.6 liter engine - everything is bigger, most likely the radiator cap as well.
