Well, here’s a tip for anyone in the future who may be installing the later type heater in a Mark V. Put it in BEFORE you put the body on the chassis, or before the engine is in the way anyway. I’m sure that’s the way the factory boys did it.
Otherwise you’ll need to take the air cleaner and valve cover off to get the two top bolts in.
And you’ll need to learn the two finger method of putting washers and nuts on the three studs of the heater core, and I hope you don’t have fat hands.
Well anyway it’s in.
This model from Smiths has an air bleed valve at the top, protruding through the scuttle, so you can let the air bubble out when you fill the system.
And after going to a lot of trouble restoring the 10 original Terry hose clamps, I discover they won’t fit, the new hoses are thicker wall, a bit larger diameter than the old ones. Scrambled around and found 10 larger clamps, some Terry, some Jubilee, some Swedish, one American.
Water test tomorrow.
