Replace the leaky, unreliable quick-disconnect elbow on the bottom of your 2011-16 Ford F-150 coolant reservoir! This hose is part of the pressurized cooling system, but the clip-retained hose often leaks where it meets the reservoir. Our repair kit replaces the stock hose with a more reliable clamped connection.
1x RE9025.19-Black Silicone Elbow, 1" to 3/4" 90 Degree Reducer
1x HJ19 Aluminum Hose Joiner, 3/4"
2x 3613-1.25 Lined Hose Clamps for 3/4" End
2x 3613-1.75 Lined Hose Clamps for 1" End
Remove the stock clip-retained hose from the reservoir and from the lower hose.
Install the aluminum joiner in the lower hose and secure with one small hose clamp.
Slide the small end of the reducing elbow onto the aluminum joiner, securing with one small hose clamp.
Slide the large end of the reducing elbow over the nipple on the coolant reservoir. Be sure to slide the hose far enough that you can position one of the large hose clamps above the clip slot. The hose should very nearly touch the reservoir body. This is critical to prevent the hose from coming off under pressure.
Install one large hose clamp on the reducing elbow below the clip slot. This clamp will create the liquid-tight seal.
Install the second large hose clamp on the reducing elbow above the clip slot. This clamp will keep the hose in place.
Installation usually takes less than 2 hours.
This kit fits 2011-16 Ford F-150 with 5.0L V8, 3.7L V6, or 3.5L V6 EcoBoost engines; and 2015-17 Ford Expedition / Lincoln Navigator with the 3.5L V6 EcoBoost engine. Does not fit the 4.6L, 5.4L, or 6.2L V8 engines.
