DO88 Silicone Coolant Hoses 

To Fit:

• Seat Leon / Cupra (MK3) 2013-2018 1.8TSI, 2.0 TSi 
• (does not fit EA888.3 engines from 2019 onwards)

A performance silicone hose kit developed by do88 to replace OEM radiator/cooling system hoses!

These hoses are entirely manufactured in high quality silicone for best finish and durability. With three to five layers of armoury, depending of the inner diameter, the hoses withstand high pressure rates and high temperatures for a long time.
The original hoses are manufactured in rubber that often cracks from age. This is a durable solution for you that in addition improves the looks!

Please Note: You must reuse the original hose connections. The original hose clamps need to be cut with a hacksaw (easy). The hose connection is mounted on the silicone hose with a regular hose clamp. This means you must have new hose clamps ready to use for fitting these silicone hoses if you do not buy our own matching clamp kit at the same time.
