MK8 GTI/Golf R 2.0T Evo4 Silicone Coolant Reroute Hose

The factory expansion tank coolant hose that runs over top of the intake air scoop can be quite a let down when installing an aftermarket intake system. Leaving an out of place and unsecured hose on top of your brand new cold air intake simply ruins the look underneath the hood! 

Introducing our ECS Tuning Silicone Coolant Hose Reroute Kit. Designed and engineered in house to take the less obtrusive hose routing and direct coolant underneath your intake system for more pleasing underhood-aesthetics. This coolant hose connects the upper radiator hose bypass fitting to the expansion tank return line. 

PART DESIGN

• In-house designed and engineered using FARO ARM laser scanning technology and SolidWorks 3D CAD modeling for precision fitment 

• Made from 3-ply black silicone which offers better resilience over factory rubber hose

• Designed to handle 250° Fahrenheit continuously and tested up to 44.1psi for long lasting, dependable operation

• Includes T304 stainless steel smooth-band hose clamps to replace the OE constant tensions clamps 

PRODUCT DEVELOPMENT

• Our ECS Coolant Reroute Hose was designed, engineered, tested and quality inspected by our Research and Development team in our Wadsworth, Ohio facility. We strive for the highest level of precision and quality through leading-edge product development technology including FARO laser scanning for reverse engineering and quality inspection, SolidWorks 3D CAD modeling, rapid prototyping utilizing our in-house 3D printer, and rigorous long term product testing.

INSTALLATION AND SUPPORT

• Some coolant will be lost during the transfer of stock to our ECS hose, but if you work quickly you can minimize fluid loss.
• Start by removing the top hose (engine side) and install our ECS hose. ** Removal of the OEM hose will require cutting of the factory clamps **
• Move on to the radiator hose connection (body side) and quickly swap hoses in this order: 
  • Have 1 or 2 rags handy to catch and absorb any lost coolant 
  • Remove the hose and quickly cover with your thumb 
  • Install the ECS hose and clean the engine bay 
  • Tighten both hose clamps 

• **NOTE** Fitment may vary for other brand air intake systems. Please reference our installed photos for a general overview of hose routing.
