issues preventing me from getting my car back

In 1 of your photos the bottom rad hose had a kink in it but a mechanics hand was at the rad end? so i discounted it as thought during fitting photo.

Pressurise with water pressure from a garden hose. fill that rad manually with the hose. coolant can be added later on.

Right guys the problem has been solved but has introduced another problem! Story of my life, we cleared the air block by using a old fuel pump to push water into the system with some grunt rather than gravity and that worked perfect.

Stable temps around 70-90 dependant on time running etc BUT that was on a high idle when we tried to introduce a idle of 300 less so 1000rpm the temps just kept rising, but with a blip or two of the throttle the temp drops right back down. Now we are sure this is because we are running a underdrive pulley and such a big rad which the stock water pump just can't flow on slow idle so that leaves us in a position.
These are the options I see


Can either run at 1300 rpm and do my tree in at every traffic light or stop.

Replace the rad with something smaller and settle for a slightly higher running temp

Or

Jncorporate some kind of inline electric water pump to aid flow with a bypass or find a oe for electric water pump for he Fd which I don't think exists.

What say you guys

Clives got David Craig electric waterpump on his car....fd block....id wait and see for Clive to come along....

Yes, really happy with the electric pump, but I feel for you it would just be trying to get around a problem as its still  probably poor flow with that weird top hose header tanky thing that's  giving you grief.

It could well be that even with the electric pump you would still have the same problem if the system cant flow .

Personally I  don't like, and have never run under drive pulleys as the last thing you need on a hot day is a water pump running slow 

As for power increase, years ago we had Performance Ford borrow the ramp for a back to back, stock verse underdrive pullys on a standard  Focus

Rolling road showed a 2 bhp drop at the wheels

I totally agree and I am in the process of sourcing a good condition standard size pulley/ belt and tensioner as I have air pump and OMP delete
