Hi There

I am after some help with regard to pinto plumbing.

I have a header tank that has three in/outlets and a pressurised cap.

what I have worked out so far is

1 - the bottom feed from the header to a connect to a T-piece to the lower rad to waterpump hose

2 - Upper Rad to Thermostat

3 - By-pass system, Small water pump hose to inlet manifold.

This leaves me with two connections on the header tank, which of the following do I go with?

4 - Small thermo, currently blanked off, use this to go to the top of the header along with the rad overflow using a T-piece, blanking off the middle middle inlet/outlet on the header?

or

4 - can I the small stat take-off (currently blanked) and return to the upper header tank in/outlet with the rad overflow going to the middle inlet/outlet on the header tank.

Thanks, much appreciated

Mike

I used to have a pinto so the older pictures in my gallery my help.

My header tank has an outlet and an overflow.

1 - as yours
2 - as yours
3 - as yours

I have small thermostat to header tank overflow.

I have the rad overflow blocked with a screw so that I can still use it to bleed when refilling the system.
