This is proving to be a nightmare, after getting no joy trying the Astra type recommended to me I tried Roose Motorsport, who were happy to split the GTE set and send me a bottom hose singularly. It arrived today and when I tried it it was know where near, it was just the same as my other non GTE nova hoses.
If anybody does have a GTE or GSi bottom hose handy please can you check a couple of things.
1. The Hose diameter at the water rail end in 40-42mm and the radiator end is 35mm.
2. The distance between outside edges, measured left to right on the car is approx 265mm.
Thanks
