I thought the Coupe was early engine front dipstick so has your engine been replaced?

I have a decent fan but possibly like the Scim it’s a long way from the engine so my theory is s bit of extra help wouldn’t go amiss particularly when stuck in traffic and there’s no ram effect

Why wouldn’t a front cover front dipstick conversion be able to check the oil level? A change from rear to front dipstick to get a high rear sump is done on specials etc....
If you have a later rear bowl sump and block mounted dipstick tube , then how can you expect to dip the oil if you move the dipstick to the front of the engine . There is no depth to measure!

Maybe I’m missing something here as I’ve not read the whole post thoroughly

Very early Scimitars had a mechanical fan, but it was soon replaced by electric, and the mechanical one became an option for towing, but in both cases the mechanical fans were mounted on the crank pulley.

Aha thanks Roger wonder if anyone has an old crank fan?

I’m front bowl front dipstick so no fan provision - that’s the question basis really. If I was rear bowl then a front cover would off the shelf, well almost!

No our coupe still has the original engine just without the original fan and cowling you will also need to duct the air

I think we discussed this last year by email.if you remember i and a growing number of owners have indeed fitted a mechanical fan back on the engine either on the crank pully and in some cases actually on the idler pully.The usual one is a plastic mgb item.Dispite the many comments that its not needed it has reduced fueling issues in most cases and also moves a lot of hot air out of the engine bay..

Unfortunately emails over 5 months old are gone due to an account hacking/deleting thing but that’s another story!

You photo there has a large pulley of the later type so it could also take a fan so I wonder why it’s fitted on the crank pulley, and in any event what the fixing details are for it to fit on the crank.

Thats on my 5a .Its on the crank as the spare wheel and chassis crossmember are in the way...you may have room on your TVR to fit it on the idler pully.Get a mk 3 capri type.

It’s fitted on the crank pulley because the rad is so low that it wouldn’t be cooled if the fan was on the idler pulley (as per Ford). I’m pretty sure I’ve seen a later front cover with the full front dipstick tube boss (but not drilled), on an Essex engine from a Ford.

Yes that as well ..it does draw some air through the rad even though its not up against it...

I’m still hoping there’s one of those somewhere !

A front engine driven fan will aid cooling on hot/modified early engines and here is what I have found - hopefully it will help someone doing a rebuild or with cooling issues on an early front sump block:

Timing covers:
1. Early V6 cover - hole for fan shaft only, offset to the left. Either with a strengthened boss or without like this:
Ford-Essex-V6-timing-cover.jpg

This would need an idler shaft for the fan like this press fitted :
s-l400.jpg
s-l400.jpg (113.99 KiB) Viewed 366 times
2. Late V6 cover - fan shaft central but no dipstick hole or boss. This would work but the dipstck hole will need forming with a boss so a bit of ali welding would be needed:
s-l1600 (5).jpg
s-l1600 (5).jpg (173.19 KiB) Viewed 366 times
2. V4 Transit or Corsair - fan shaft present, offset to the left. Many are no dipstick hole just a boss, like this:
s-l1600 (6).jpg
s-l1600 (6).jpg (116.24 KiB) Viewed 363 times
BUT there are versions with the front dipstick like this:
s-l1600 (4).jpg
s-l1600 (4).jpg (140.75 KiB) Viewed 366 times
Now these are ideal but the offset may be an issue if the fan is likely to be hitting hoses/electrics.


The best options therefore seem to be:
A. If the fan in the offset shaft position wont foul anything then go for a V4 transit/Corsair with a front dipstick, or if it fouls anything then:
B. Go for a late cover, weld a boss on and fit a dipstick tube

There is always a C: Find a crank mounted fan that was apparently for towing and fit it!
