Turbo cooling hose, what size, where to get?

Post by **Blacklab467** » 14 Sep 2023, 19:42

Does anyone know where to get this hose? I am looking for Volvo branded hose part #10 in the picture. Number 9 is still available and about 10 bucks, number 10 says no longer available. FCP sells an aftermarket silicone hose in a rainbow of different colours but I don't trust this stuff. Thanks.

Weird part. When you look that part up (Part # 30713395) it says it has been superseded by part # 31439471

However, when you look that up and check what it fits it does not list P1 XC70's but it fits all turbo FWD P2's??

Maybe worth talking to Volvo about getting clarity on this??

I'm replacing these turbo cooling hoses so I have recently looked them up. I came up with

9471700 hose 9
31439471 house 10 (upper position in diagram above - lower is not used in most cars)

In the US both are available from many suppliers; you'll probably have no trouble armed with the part numbers.

Note: I actually decided to go with the silicone ones from FCP so I can't confirm fitment of 31439471.

I like using stock on those. They sit near the hot exhaust manifold so quality rubber matters

That’s why I went with silicone - better heat tolerance than rubber. They are longer lasting; replace them once now and be done.

Those turbo cooling hoses are so small that I don’t think any increased porosity will matter. But I watch the coolant tank anyway.
