Hi, I have put a 2.5 na diesel into my series 2A. Does anyone know what top and bottom radiator hoses I should use ? I still have the original 2A radiator with straight connections on the rad. Do I need to change the thermostat housing top ? Any info greatly appreciated as I'm kind of stuck for plumbing it up. Many thanks.

Mine has a series 3 rad with a 2.5 NA.
The series 2.25 top hose 569955 fitted ok and the same with the bottom hose. And I didn't need to change the thermostat housing.
Don't know if the 2a radiator is different.

Which direction does the top hose outlet on the engine point too.
I had a 15J 2.5b fitted and that had a 2.25 top thermostat housing fitted to get hose to fit.
Can just be seen in this photo.

Hose ot of line in this one but shows housing.

Hi, thank you for the replies and info. Greatly appreciated. The inlet on my thermostat housing is not straight up like in your photo's. mine is horizontal. As you look into the engine bay from the front, it sticks out to the right. I think I need to change the top part of the thermostat housing. Do you think a series 2.25 diesel one would fit ? Many thanks again.

The bottom hose is being a pain too. The series hose obviously fits the rad fine but is just a tad too small to get onto the engine flange, even a bit of washing up liquid wouldn't persuade it on.

Tried warm but not hot. Something to try next. I'll stick it in the top of the kettle when the mrs is not about. Lol.
