Cooling problem

[lmrdave]

Right this one is getting me down, I know what it is but I can't fix the chuffin thing!

Rad was leaking and then started getting air locks, found only by chance doing my daily water top up's, as temp gauge read bang in the middle.

Decided to get a replacement got an alloy S13 rad finally got it mounted, but I still have problems with air locks, and I can't bleed them out!

Symtoms are very hot top hose and top of rad, but bottom hose is stone cold. Temp gauge reads normal running temp.

Thought about taking the thermostat out but I can't think it's at fault as it's allowing hot water to the rad.


Tried bleed it again twice tonight with no joy.

Any ideas welcome!!
