Just re read that old post and noticed you had read it yourself 

As MarkDTM and Daz said, give it a try, it worked for me 

Leave the fernox in there for a couple of days or longer if you can.

hth 

Does the rad have to come off ? Just thinking about blocking the pipes off if i can , then filling it with the rad flush  then again i wont be able to reverse flush it 

Yes, pull it out and lay it flat on the ground in you back garden.
I blocked up the holes with a few poly bags and some gaffa tape.

As mentioned before, leave the fernox or similar stuff (I got mine from B&Q) as long as you can 

Ok thanks for your help TG  Looks like a weekend job as cant take off the road till then ....will give it a try 

Failing that it will be water pump next 

Thanks all

Cant remember who quoted this but could this be why my rad is not being as eficient as it should be .

SLudgepump = autogearbox

box to air is gearbox heat exchanged in radiator to cool it
I.E gearbox cooler built into side of rad thus making the rad do more work
 

 

Oil cooler in rad blocked , hence the faster the box works the hotter the rad will get from all the sludge . Internal auto box cooler blocked inside the rad

Unlikely - refers to small "oil cooler" for autobox built into drivers side of radiator.

The side of the radiator is where most autoboxes have their ATF cooler fitted as standard.

When its off the car i will check the flow to the AT fluid cooler ....

Gearbox works fine , would of been issues with the box me thinks if it was over heating the ATF

You're barking up the wrong radiator tree

Don't try and "flush" the gearbox atf cooler mate - just the main radiator

[omega3000]

Ok  Have sent you PM ....ill just flush the main rad 

[albitz]

And make sure you dont get any water or foreign objects in the autobox cooler while cleaning out the water rad.

Will do albs 

Guess its a hit and hope job that the rad cleaner will do its job working its way through every fin , looking at all the advice it does add up to the fact that the flow is getting blocked and pumping back up through the header .

On with the job , ill be taking the rad off later once i can get the rad cleaner
