DS4 2012 coolant pipe identification

Unread post by andyps »

I was changing the crossover pipe on my daughters DS4 200 THP today and one of the other pipes has broken. It's a thin pipe which connects to the hose going from the back of the thermostat to the bulkhead Circled in purple on the picture) from where it runs to the front, goes across the top of the radiator and connects to the front of the expansion tank (top half).

Does anyone know the part number or correct description of the pipe please so I can get one ordered?

I think that it is 1323HJ which is unique to the 200HP version of the THP engine.

Many thanks - I'll double check but that does look right.
