## Questions & Answers

**Q: Does it 2015 gmc yukon xl denali**
A: Cap Asm-Rad Fil - GM (13502354)

**Q: Will this fit an 07 Grand Prix Base?**
A: yes

**Q: Does it have a spring on it**
A: Never be fooled by GM "Original Equipment". It is NEVER the O.E. part that came on your vehicle from the factory. No matter if it is a radiator cap, a fan clutch, a water pump, whatever. If it is labeled/described as a GM "Original Equipment" part, it will either be made in Mexico, China, or sourced from another nonGM affiliated manufacturer, that never manufactured an O.E. part for their vehicles ........just put in a GM Original Equipment box/package, and sold at a very very very inflated price, to another successfully conned customer!

**Q: Will this cap fit 2006 Pontiac grand prix**
A: I think it don't fit because the Pontiac I believe have expansion tank and the cap is different. GMC savana have the cap rigth at the radiator "neck."
