P38A Going through radiators- not overheating

You don't need to go behind the dash, the pipes stop at the fire wall under the bonnet

Getting the dash out wouldn't cost you money if your doing it yourself

What's worse, getting the dash apart to reach the heater matrix, or doing a head gasket?

Both are fairly easy on a P38, but IMHO the dash is less work. Leaks usually stop the coolant pressurising, but also allow it to boil, so eventually there will be excess pressure.

As you've founbd one leak, do a coolant pressure test with the engine warm but off. Much easier to find hidden leaks that way.

Never had the dash out but even the thought overwhelms me. Much rather do a HG.
Where hoses connect to are usually corroded or covered in junk.. they need cleaning up properly to get a good, lasting seal. Also jubilee clips are ready to make a mess with because they don't stay round, meaning there will be a weak spot

There shouldn't be any Jubilee clips. The fixings should all be self-clamping spring hose clips that apply an even pressure. They are much easier to remove & replace than jubilee clips too just need to get them on & off with a pair of Flexible Wire Long Reach Hose Clamp Pliers

Agree totally. Some of the Britpart hoses i got came with jubilee clips though
