T peice for coolant system

Hi

Fitting a new rad to my jetta with an expansion bottle got the bottle just trying to hunt down a t peice for the top hose that's gonna come off the rad and one to thermostat and one to expansion tank? Anyone know of anywhere that supplies one and what diameter pipe should I look for? Any help would be appreciated

Cheers

Olie

Has anyone got any idea on a top hose I can use? Anyone?

This will be the sort of thing your looking for, but youl have to check your existing hose to find the correct bore size needed
