Hi

Anyone got a decent 2nd hand one or new? Mine's is the red one, I've seen black ones, not sure of difference.

Thanks
Andrew

A quick Google came up with THIS and others at similar prices.

As said on another thread, I'm sure the genuine GM black plug does not seal properly in a rad that came with a GM red plug, so they are not interchangeable.

Slight difference on prongs and tread.

[Doctor Gollum]

The prongs are only there to stop it falling out when undone. The black one also has a slightly longer thread, but neither should prevent it from working.

OEM type plugs might not fit pattern radiators and vice versa.

Thanks ECP had a febo one so got that. I never got a new washeer though, which looks crusty so will be getting that next.

When I replaced mine last year, it didn't come with the washer. My original serrated washer had surface rust, but it's quite substantial so a quick wire brushing and some rust convertor, and it's back in with no signs of further rusting. I reused the old one to ensure correct fitment as I didn't have any new ones similar, and visiting different suppliers just to get an appropriate sized serrated washer would have been relatively time consuming.
