Anyone on here owned this Buick?
Discussion
I've just bought a rather lovely old Buick RoadMaster 75, and noticed this...
...on the rear bumper. Anyone of this parish?
I'm hoping this is a long-term keeper, having gone through dozens of old motors over the last few years. It needs some TLC in places, but seems pretty solid where it matters. We'll see.

He had it briefly, though I didn't buy from him. I did a 4 mile drive today and the rad blew. Parked up, there was a loud 'pop' and all the coolant dropped. Header tank had been bodged (badly) with filler. Not a great start. Now need to either repair it, or get one custom built. 
That is a pain Ade. You should be able to have that professionally repaired by a radiator specialist. Get them to flush the rad as well while they are in there It's in good hands. They say that it won't be a problem.
But it's a hell of a split, as you can see. No idea how that much pressure can build up in the cooling system. I figured maybe a head gasket, but there's no evidence of water in the oil, or oil in the water. Any ideas? 364 Nailhead.

Good point. Looks like I'll need to source an original one to bolt to the pulley on the water pump.
Whichever you keep, get a shroud, that's where the real gains come from.Personally, I'd have a flat shroud made with a cutout for the electric fan and a few bypass flaps. Wire it in with a thermostatic switch and an over-ride and it should see you good.
Just as an update;
I found a contact for the original owner, who imported the car to the UK in 2016, and sold it a couple of years ago. We had a long chat, during which he mentioned a Davies-Craig electric water pump he'd installed. This is no longer fitted.
Part of the process of fitting this pump (into the lower radiator hose) is to remove the impeller from the standard water pump. Whoever removed the EWP (for whatever reason) obviously wasn't aware of this. So, during my 4 mile drive, I was running around in a giant kettle, as there was no way for the coolant to circulate. Pressure built up, and popped the rad.
I have a new EWP with uprated controller....

...we'll see if this cures the issue.

The radiator cap must be defective, it should have been squirting like a geyser long before enough pressure built up to pop it like that.
It may well have been venting. When I stopped, I heard a hissing, accompanied by steam, just before the 'pop'. The header was plainly weakened, as evidenced by the piss-poor 'repair' so burst before all the excessive pressure reduced. It's a fairly new 16psi cap like this... https://www.demon-tweeks.com/stant-motorad-racing-...

Maybe wrong but i think the car was on a stand up for sale at the NEC ,can't remember whether it was at the Restoration show or the Classic Car Show...on the rear bumper. Anyone of this parish?

Would it have been this show? The original UK owner (not the one I bought it from) sent me this photo from his files.just before or just after Covid , thought it looked cool then.
