Hose Quality Recommendations. [Editor] Hoses: The BEST quality hoses come from Volvo: they seem to last much longer than aftermarket hoses, even those labelled "OEM" by aftermarket suppliers. See the photo to the right of three turbo coolant hoses, from the top: new Volvo, 225k miles Volvo, and 15k miles/2.5 years aftermarket. Note the pronounced hose rot in the bottom hoses despite being only 2.5 years old. In this case, the aftermarket hose failed, causing a massive coolant leak. Because your cooling system is so important to engine lifespan, this is one area in which you do not want to economize. So buy Volvo brand hoses from a dealer or reliable supplier who can obtain the originals.
Hose Clamps: For super reliability, use Breeze stainless band Liner clamps which never rust and do not cut your hoses. Volvo OEM clamps are a good second choice; avoid the screw clamps with screw threads cut through them which tend to wear your hoses.
