Sodium Silicate syrup is another trick that actually works. It was the classic way of curing the 'Ford Porous Block' syndrome of the 'Pre-Force' Ford 3000 and 4000 blocks.

. . . .twiddling my thumbs as new radiator hasn't yet arrived . . . I don't do patience  :clap:

I remember, some 45years ago, I fixed "temporarily" a leaky top tank on my '52 landrover with glaziers putty, I forgot about it and it lasted a very long time!

Cheers, Matthew

Drop of sikaflex up the core tube would sort it :D
awemawson:
The trick used to be to grip the offending core tube with snipe nosed pliers and roll it up either side of the burst to form a seal. Once rolled grip the rolls again with the snipe nose piers and squash them to form the seal.

(This is still a useful trick to know when crossing the desert with no radiator shops for miles as it uses no materials ! )
awemawson:
The new radiator arrived at lunchtime, but to my horror when I unpacked it it was damaged  :bang:

However it really only was superficial - the squashed port for the bottom hose dressed out OK and the crushed fins probably don't make a jot of difference to the cooling. OK I could demand a replacement but there seemed little point. I've told them and sent pictures but life is too short to get too excited!

So I fitted it, did a low pressure leak down test with air, then took the risk putting in the rest of my antifreeze solution, having lost half of it on the floor with the last escapade!

No leaks apparent so far - I've run the engine at a fast idle (1250 rpm) for an hour, with the front of the radiator blocked off with a towel, but can't get it warm to give it a true test. The gauge just perceptibly moves off it's cold resting point - but it is quite a chilly day. 

Not put the bonnet etc back as it'll be easier to change all the filters with them off.

Incidentally, the rev counter that stopped working in the last 'coolant change' episode is now working fine. Either the coolant that was gushing out and splashing everywhere from the split radiator got into the alternator and stopped the W terminal working, or as I now think more likely, the Vee belt drive was wet with it and slipping.
