one radiator not working,

[ajoint]

can anybody help,i have one radiator that is hot in certain places of radiator,i have bleed radiator so it is not an air issue,thanks,ajoint

are we talking hot at the top but large cold patches lower down, if it is sounds like sludge

a powerflush might shift it, but youll be better off getting a new rad,
either way magnacleans would be a good addition

Sludged up. It will be in the system as well. Have the system powerflushed.

plumber0808,can i not take that one rad off and say stick a hose pipe in one of the tappings and flush out like that?ajoint.

You could do that to shift most of the sludge from the rad but there could be sludge else where in the system that may shift and cause problems again, power flush and consider installing magnclean they are a great Job.

That's a good place to start!

Agreed, a powerflush is a little excessive as a starting suggestion imo.
Take rad off, flush through with hose, put it back and refill. Make sure you have inhibitor in your system.
If the problem re-occurs then look at a powerflush.
