other possibility is an airlock. try running the car with the header tank cap off for a while to get rid of any airlocks.
also what make is the rad? there have been a few cases of poor quallity rads not flowing properly
The fan swith is not genuine ford, the brand is FAE, but long ago I dont have a genuine fan swith.
When the fans are on, it seems that the original temp gauge dont move, the needle is always in the middle.
Tha radiator is an alloy one , is brand new a and is XS.
I have fitted a swirl pot.
