Top hose size?
Any one know the internal measurement of the top hose on a standard impreza rad, need to order a temp gauge fitting and don't want to undo my hose just yet. thanks.

I can't say for that model, but mine, a 98 UK car, was 38mm.
BUT: when I replaced my rad, I obviously had to remove the top hose from it. Under two days later, the top hose sprang a leak. Only a pinhole but CLOUDS of steam, very alarming.
Anyway, removing it for replacement showed that the inside looked like someone had taken a sharp scalpel to it, it was criss-crossed with tiny splits. I reckon manipulating it for removal caused one to go completely through
My advice: do your job, but with a NEW top hose.
Oh, and PLEASE, do a search on here for how to drain and refill WITHOUT airlocking
Or your next post will be about headgasket failure 
Under my username will find one.
