Just fitted new water pump and thermostat problem is top radiator pipe is hot bottom pipe is cold, heaters inside car are nice and cosy , The radiator seems to be free of blockages

Thanks in advance for any help guys

haveyou definitely bled it properly?
 did you test the 'stat before you fitted it?
 maybe try backflushing the whole system just to be sure then run it upto temp and bleed it again..

I think I have, not tested it as it was brand new. From what I've read there seems to be a few ways of bleeding the system ?

Cheers Alan

Its unlikely but thermostats can be faulty straight out the box - drop it in some boiling water and see if it opens or not.

 As for making sure theres no airlocks - some people like to drill a small (1mm ish) hole in the 'stat to help bleeding.

  I like to set the blowers in the car to full heat, fill the rad to the fill line and then pull the coolant hose of the side of the head to fill up the block which is on on the other side of the 'stat.

 When its full run it up to temperature, take the cap of the rad/expansion tank and start grabbing and squeezing every hose you can get your hands on. pop the cap back on, take it for a run then top up if you need to.

dead easy  

Cheers nick sounds so easy when you put it like that haha had enough for tonight so will try again again tomorrow fingers crossed as she was meant to be going on the road in the next few dayscf_emoticons__BangHead:

are you near manchester?  I'll give you a hand if you fancy..

Not near Manchester mate I'm from Dundee in bonnie Scotland but thank you for the offer  

this method never fails me, no removing of pipes, no drilling of holes in things that shouldnt have holes in:

addition step for mk1 is make sure heaters are on hot as the matrix feed pipe has a tap in it unlike mk2 which doesnt

I've tried it that way but no joy the top half of my rad is warm but the bottom staying cold the water seems to run freely through the rad though kinda stumped ,Gonna take out thermostat in a bit

are all the hoses in the right place?
 is it a 50/50 mix of coolant and water?
  a huge rad overcooling an 1100 maybe?  

So turns out the brand new thermostat is daffodil checked it in boiling water not a bit of movement ,was a brand new radiator switch aswell but fan still not kicking in so looks like faulty new switch aswell what are the chances ??? getting there now though haha cheers for all the advice

Where are you buying your parts from?  

 A lot of the time, motor-factors will have two lines of products, for example GSF do the 'standard' bits and the 'premium' bits, and more often than not the 'standard' are crappy cheap chinese copies of the 'premium' parts which are OEM…

 When you take your old 'stat back for replacement, take a mug with you and ask if they have a ketttle in the back (I'm serious!) that way you can check it works before you leave the shop
