## Description

ACDelco Professional, premium aftermarket Molded Heater Hoses are specially designed, factory-molded hoses to fit todayâ€™s smaller, tighter-fitting engine compartments. The hoses are GM OE style, meaning they are molded into the GM Original Equipment style and shape. The hoses are composed of a proprietary blend of EPDM rubber, which is a superior blend of synthetic rubber that is more pliable, ensures a longer hose life, and helps resist electrochemical degradation (ECD), the leading cause of hose failure. ACDelco Professional Molded Heater Hoses are temperature rated from -40 degrees Fahrenheit to 275 degrees Fahrenheit (-40 degrees Celsius to 135 degrees Celsius) and can be used for coolant, water, and air applications and are also approved for Marine applications. Do not use for fuel or oil transfer applications. These premium aftermarket replacement molded heater hoses are manufactured to meet your expectations for fit, form, and function.

## Questions & Answers

**Q: What are the sizes of the three connections on the y connector?**
A: Sorry I didn't have to measure the size I just ordered OEM hoses and they fit perfectly.

**Q: Good afternoon, do you have the engine heater hose assembly for a 2012 dodge Journey 2.4l, thank you,**
A: Look up the hose no. In your operators manual. Punch that in the amzon search. Also enter your vehicle into"your garage" on the Amazon site. It will tell you if the component fits. Hope this helps.

**Q: Does the fitting at the y require hose clamps or is the plastic fitting at the y enough ?**
A: The y is already clamped to the hoses.  No clamps are required there.  You will need clamps on the all the other ends that fasten to the heater, water pump and reservoir.

**Q: K1500 1998 does it work on ok older models**
A: I don’t think so my 1999 C-1500 is definitely different.
