So I've finally traced the leak to the plastic Y piece under the throttle body, the bottom hose on the Y is weeping where the hose clamp is, I have replaced the hose but looks like I need to replace the Y piece.

 

I think I have to remove the TB in order to have access to the Y, is there an easier way, if not how do I remove the TB to gain access?

 

Thankyou.

What engine?

This is the part in question, this is the new piece held above the old piece in situ.

Can it be replaced from the top/bottom, or does the throttle body have to come off?

Ok.

That plastic quick connector fits onto the thermostatic housing. It's all tight in there but it is a quick connector. I'd probably suggest removing the two lines with spring clips. Then the old quick connector. If you've got that far, assembly is reverse of that.

I suspect you may like to remove airbox, intake and upped radiator shroud, fan assembly out. But try without by all means.

Many thanks, I'll attempt shortly...
