white90 Posted March 26, 2009 Share Posted March 26, 2009 Swap the rad top one as well whilst there the plastic ones go brittle over time. http://www.x-eng.co.uk/X-Cap.asp Quote Link to comment Share on other sites More sharing options...
teabag Posted March 26, 2009 Share Posted March 26, 2009 £1.40 from B&Q not £9.39 delivered from X-Eng. Quote Link to comment Share on other sites More sharing options...
First_Fleet Posted March 26, 2009 Share Posted March 26, 2009 But don't tighten those excessively or the O ring can squeeze out. The OEM ones have a peripheral groove for it to sit in so it doesn't deform. Quote Link to comment Share on other sites More sharing options...

What about the B&Q one with some PTFE tape? Quote Link to comment Share on other sites More sharing options...
First_Fleet Posted March 26, 2009 Share Posted March 26, 2009 Probably a 2nd line of defence & it can't hurt. Quote Link to comment Share on other sites More sharing options...
PaulN Posted March 26, 2009 Share Posted March 26, 2009 Probably a 2nd line of defence & it can't hurt. I meant leave the 'O' ring out and use PTFE which seals the thread and acts as a sealing washer? Quote Link to comment Share on other sites More sharing options...
First_Fleet Posted March 26, 2009 Share Posted March 26, 2009 I have left the O ring in but just not flattened it when tightening. It just needs a bit of care is all. The one shown is a parallel thread, so I doubt you could bin the O ring. Quote Link to comment Share on other sites More sharing options...

The brass plug is laying in the tool box just in case its ever needed. I have a selection of O rings again from B&Q so may try a thinner one or even a fibre washer when the time comes. But I think replacing my plastic plug will be a long way off, I'm now using the red long life anti-freeze so the plastic plug only has to be removed once every five years, and as the anti-freeze has only been changed three times over the last eleven years the existing plug still looks as new.

I reckon thats just tempting fate . The one on the engine on my 300tdi cracked whilst being driven, luckily I stopped around the corner from a brass fitting wholesaler. Bugger of a job removing the damaged plastic one. Now both are replaced with proper brass plugs. Quote Link to comment Share on other sites More sharing options...
First_Fleet Posted March 27, 2009 Share Posted March 27, 2009 I thought the reason for replacing them was heat effect, not corrosion. Obviously. I didn't give it a chance to let me down for either reason. Quote Link to comment Share on other sites More sharing options...
tuko Posted March 27, 2009 Share Posted March 27, 2009 I bought 4 alternative brass plugs on eBay that have the O seal groove built in. Basically they are identical to the originals but are a metal not the unreliable plastic. Todd. Quote Link to comment Share on other sites More sharing options...

teabag Posted March 27, 2009 Share Posted March 27, 2009 Ok tuko, I have seen that site before. The important part is that groove to retain the O ring, which the brass plug from B&Q or any other plumming materials supplier doesn't have.
