Right, just been out to check as well as i can, and the bottom feed into the water pump is squishy and the top one isnt quite solid (you can crush it easily)
So im thinking warm stuff? As there isnt 'solid' ice anywhere???
No. The problem isn't melting the ice, its the damage it has done!
... You really should pressure test the system, check for risen core plugs and check the condition of the waterpump bearings/impeller before even thinking of starting.
Right, got my head screwed on again now so lets start again.
Been out just now and took off the bottom pipe which let out lots of slush, so i can assume for now that the waterpump is drained. I also undid the top pipe to reveal a rad full of ice.
Where abouts are the core plugs on a 16v engine, had a look about with my phone but couldnt really see propperly but nothing seemed to be pushed out of place. I can only assume this means one of two things...
a: the block froze and didnt push the plugs out (or what i think are the plugs)
b: the block isnt fully frozen
:embarassed:
