Warranty Details (1 Year Warranty)
The Dayco curved radiator hose features knitted reinforcement, a protective sleeve and a synthetic EPDM rubber construction for high-strength performance, protection against abrasion and resistance to oil, mud, salt, road debris, ozone and coolants. It can also withstand temperature variations of -40 Deg. F (-40 Deg. C) to +257 Deg. F (+125 Deg. C). The inner base tube is reinforced with knitted rayon for maximum strength and burst resistance for the life of the hose.

Would not recommend
Staff Reviewer -
Leaked before the car was even started! Didn't get the antifreeze reservoir full before it began leaking.
Bottom Line No, I would not recommend to a friend
would not buy again
Staff Reviewer -
Leaked before I even started the car! I replaced several hoses at the same time as this one and had no issues with leakage. This one was showing a drip at the factory installed tee even before I finished filling the reservoir. I will use a different brand in the future.
Bottom Line No, I would not recommend to a friend
Lower radiator hose
Staff Reviewer -
Took about 1/2 hour to install and required slight trimming of about 1/2" on one end of hose for exact fit. Works fine-no problems.
Bottom Line Yes, I would recommend to a friend
1999 Taurus DOHC Curved Hose
Verified Buyer -
When installed, the hose was kinked. It isn't long enought to cut to fit because of the design (Ford). Leaked and I had to use a regular clamp to fix this problem. I hope the kink doesn't effect the performance. By design it is hard to install and isn't a quality issue.
Bottom Line Yes, I would recommend to a friend
