thanks guys for pointers for the rad ..have fitted it all ok but for some reason the top hose is hot but not the bottom!! cant seem to bleed it although heaters are quite warm..is there a way to do it i have parked it up hill with rad cap off for 10 minutes but still the same...after the engine is off you can feel a little bit of warmth on the bottom hose on the block side of the hose but still pretty cold..baffled!

hi thankfully all sorted drained the system and refilled through header but for some reason it didnt seem totake much water and no success so what i did was undo the top hose and fill it with water with a hose and also poured some in rad as much as i could and all seems to be ok ..dont know why the system wouldnt fill from the header but there we go

Simple: it airlocks it.
Had you bothered to do a simple search on here, you'd have found the easy method.
I assume you used a 50% mix of antifreeze and water?

For the record.
With engine cold with a single entry rad.
The easy way is to
1. fill slowly from header tank.
2. press top hose repeatedly, air will burp out of the header tank.
2.1 leave cap off
3. run engine at 1500rpm until fans have cycled.
careful hot hose
4. press top rad hose again. air will burp out.
5. close cap.
6. go for a drive
7. wait for it to cool down. Remove header cap, fill up.
Or
method 2
remove top hose and fill water slowly.
Then start the burping thing again.
Check the lower coolant hose below the header tank, they are prone to leaking with age. esp bugeyes.

Or the method that AVOIDS airlocks and fills FROM THE BOTTOM:
Remove rear pipe from metal header tank, fill via that, using a funnel, SLOWLY, header tank cap OFF.When full, replace pipe.
Then run engine up to temperature watching for air bubbles and mopping/topping up as needed.
Finally fit filler cap, and go for a drive. Once it's cooled again, remove filler cap and refill as needed.
Do all this at the METAL header tank, with heater set to "hot".
