Hi guys,

a complete novice here, where do I spray ACF 50? a step by step guide for blondes would be appreciated. It is my first winter with my TD5 110 XS DC and it is alreadyd riving me potty, as with previous posts it is just the drivers door and only when cold. Obviously there are worse problems to have but it is inconvenient at best!

Thanks
Lyz

Had this prob on my 90 '08 from new. Its only the driver & front passenger doors Razz

I open the safari door - meaty metal handle, not puny plastic buttons, & crawl to the front seat. Not elegant but never failed. Once the engine & heater have run for 5 mins, the side doors unfreeze enough to open (& hand brake enough to be released Twisted Evil ) Land Rover Defenders. 67 years heritage, minimal appearance changes, still going strong all over the world.

My last few Defenders have done this on cold frosty mornings.

Unless its very well lubed, you'll struggle.

I know this is a little old fashioned, but I've always found the way around it is to unlock it with the blip (so the alarm is deactivated) and then use the key in the lock.

It's never failed for me yet.......!

This is ACF-50 (apologies for sideways picture). If you haven't come across it before it's a useful corrosion inhibitor. Used (in commercial quantities) for example to protect machinery whilst at sea for months, it's also useful on Defenders to prevent doors and fuel caps freezing but also to protect any exposed nuts, bolts, door, bonnet hinges, rivets, seams etc. Do a search on the forum for Zagato Corrosion Protection Guide which gives some useful tips.

There's no rocket science to using ACF-50. In theory it's better to remove the driver's door card to get at the lock mechanism however in practice I'd advise against it as you're likely to break the lugs off the door card whilst removing it so making the whole job a lot harder. Try spraying as per the pics below and only if that doesn't work consider removing the door card.

Once you've done the driver's door go round the whole vehicle and spray the hinges,bonnet hinges etc - it will be 20 mins well spent.

hi, just to say i had the same problem for years, so far didnt solve it on 90 TD4.
very frustrating being the only one in the street, not being able to enter is own car, having to climb through back door, or worse, having let the door close while removing the snow from windscreen, finding myself locked outside with running motor... in the snow of course.
thank you for the posts.

2008 Puma. Wife came home this evening. The rear door will only unlock by using the key but will lock by using the keyfob to activate the central locking. Only had time to spray some WD 40 this evening so will see what transpires tomorrow. Strange how it locks on the keyfob but will only unlock by inserting the key and turning it. 1982 88" 2.25 diesel
