Selling flat - should we replace radiator

[EandA]

We are in the process of selling our flat. Buyers have not done the survey yet but it's imminent. The kitchen radiator is leaking and needs replacing. It frequently makes the boiler lose pressure.
Question is - do we replace it now or keep schtum? DH thinks we should not bother as the flat is sold as seen. (And when we bought this flat no one told us the boiler was knackered and would need replacing within a year).
My conscience tells me otherwise.
WWYD?

Get some quotes for replacing the radiator & wait & see what sort of checks your buyers want to do.

We bought a house in a hurry. Had survey but said dont bother with boiler/ heating servicing as knew boiler needed replacing in a year or two. Ended up replacing boiler & all radiators. Radiator in living room didn't work at all.

We would still have bought it though. Now we have a more efficient boiler & warmer house.

New radiators don't cost a lot. I'd replace it because there's no saying there isn't other damage you can't see from the leak. If someone spots it they'll think there are other issues.

it will be spotted and shouts 'sellers don't give a stuff about maintenance, so run away or beat down the price'.

buyer does need to check a place over, as you should have done when you bought it.

Does it actually need replacing if it's newish? It might just be a maintenance issue and needs tightening up. Get a plumber round.

if the radiator has rusted through, it should be replaced.

If it has a loose connection joint, it should be remade. PTFE tape will help.

All good points thanks for the replies. I think it does need replacing - I don't know how long the central heating has been in for but we've been here for seven years and it wasn't particularly new when we moved in (obviously, with an old and rubbish boiler).

We are lucky enough to have the number of a really good and reliable plumber so I'll ring him tomorrow to get a quote
