## Questions & Answers

**Q: Will this item definitely fit in my 2014 Chevy Captiva Sport ?**
A: I don’t no I known this fits my Lincoln town and my caddy coup.

**Q: Will this item fit a 06 Dodge Ram Cummins?**
A: I would think it would because it's pretty much a universal fit with the plastic ties. there are just wires coming out with no connector so you can attach the connector from your old one. I think size would be the only concern.

**Q: what is the voltage**
A: It runs out of battery voltage which is as you know probably 12 to 13 volts depending on the charging rate. The key is making sure of 2 things. You set positive and negative voltage up so that the fan is running airflow thru the radiator right way. I bought the relay kit with it and the ground wire they provide in the kit is to small of gauge. Use at least a 16 to 12 gauge wire to go directly from the ground of the battery to the fan.

**Q: Does this mount on the outside of the radiator retaining the factory clutch fan?**
A: Hi you could do that I got rid of the clutch fan all together.You need a fan that flows more air though.
