Question, can someone give me a simple+correct ! method of plumbing this lot together ?

polo rad+ pinto+heater+expansion tank+weber downdraft with coolant connection.

answers on a postcard+small prize to the winner !

I posted a pic a while back.
Will try and find it later.

There's loads of posts on this. Have a look through the archives.

I don't have a heater or the webers (injection instead). I do have an additional expansion bottle with the micra rad

id'e miss out the inlet manifold connection, cooler the charge the better.

a short summary (agrees with all the above too, BTW) is:

bottom of rad to bottom of engine

top to top.

expansion bottom into bottom hose via tee

expansion top from top hose.

heater matrix just looped back on itself.

There are several variations in donor sierras on how the same setup was actually connected - mine had a few bits plugged when i dismantled it. So i left it all as it came
