Just changing the fan belt and discovered that this butchered adjuster was in place. Looking out for a replacement but what bolt should this be fixed to on the block? My finger is pointing to the one it was bolted on. Is this correct?

 

I don't think that's a Jaguar bracket, or at least I've never seen one that looks like that.
See photo's
When using the bolt in the photo, a spacer is required to line up with the generator/alternator.

 

 

Sorry about the duplication if pictures - don't know what went wrong there ! (I don't seem to be able to upload using PC so used mobile instead). Anyway, the last picture is inside the engine bay of my MK2 fitted with an alternator. As you can see it has a threaded bar fitted to the top right bolt, just as JeffR1 said. Out of interest JeffR1, that alternator you've shown, is that a drive on the rear for a power steering pump ?

 

I don't have a picture of it but that adjuster you have shown in the photos comes from a Rover K series engine and alternator. I had the same adjuster plate on my K series Lotus Seven but it had a screw with an 8mm head that ran along its length and was attached to the bolt that goes through the long hole for adjusting the tension of the belt. It looks like someone has cut the end piece off and removed the long screw to adapt it to fit the aftermarket alternator you have on your Mk2. Because of its length he has picked anyone of four bolts he could attach it to. On my S type the adjusting plate is attached to the nearest bolt on the front casing to the generator.

 

That adapter (and alternator) is from xks.com, it works well enough but it has a serious deign flaw, the coupling in the adapter is not rubber mounted like the Jaguar one, maybe they've changed it, I don't know.
With the steel on steel adapter, the softer metal of the drive just wears right out, and one day the power steering pump will simply stop turning. The rubber in-between absorbs the uneven load of the power steering pump. (which it's lacking)

Just noticed something, MussieRon, you're rad/fan shroud is missing.
I guess it depends how warm it gets in your neck of the woods.

 

JeffR1,

I've got a confession - mine is missing as well ! Next job on the everchanging list, lol ! Thank you for the update on the XK's alternator - looks like they are still selling the same item ? I'm in the process of converting my MK2 to
power steering and have (at present) opted for the Vauxhall (GM) electric stand-alone pump. However, I'm always looking at alternatives as I'd rather keep the car looking relatively period. I did consider an XJ (S1/2/3) pump, fitted to
the right side of engine but space is the problem (The MK2 engine bay narrows quite a lot towards the front and the brake servo pokes into the area). Thanks again. Kind regards.

 

Hi Jeff.
Sorry only just seen your message. Shroud, didn't know it had one. Will look out for one. Hope it's not a holy grail part! I've got what looks to be a complete set up for power steering. It came with a large box of bits with the car. I'm not going to put it on mine.

Hey Ron, here's a link to just one supplier.
It mounts on the radiator drain pet-**** brackets on the one side.
You will see two other mounts on the other side _ 4 altogether.

I think they were made of fibre glass, so they were not indestructible, and they're a bit of a bear to put on, probably why yours may be missing.

Thanks for the link. Another reason mine is missing is that I have an expansion tank set up. I was told that 1968 240 cars did not have this. Also the tank I had was home made and was horrendous! I've since changed it to one from an e-type which looks so much better. I have no idea what radiator I have on mine. Might be from the bigger engine models but unless I can find a part number or can compare it I think I'm stuffed!

 

There is no other radiator from another Jaguar model that will fit the body style you have, the one out of an S-Type may fit, but there would provisions for the shroud.
It may have been re-cored at one time, but the tanks would be Jaguar that is for your model.

 

Totally agree with JeffR1 - the fibreglass shroud is an absolute pain to fit ! I bought mine from David Manners in the UK. In the end I found the best way was to cut it in half (in the vertical plane) and make a couple of mall aluminium brackets to fix them back together once in position. The shroud certainly made a difference to my MK2 (fitted with a 4.2 engine) - it kept the temperature gauge just below the centre whereas before it was running slightly hot. Without the shroud the fans air goes everywhere instead of being directed straight at the radiator (I've also fitted an electric fan in front of rad just in case ...)

 

Thanks Jeff and CaptainQ

On the jollyroger link below it says, and I quote,
"This is a good original used cooling fan shroud for a Jaguar Mark 2 or MK II 3.4 or 3.8 (the 2.4 used a different shroud). It is in good condition for its age, no broken pieces or cracks although the fiberglass is a little ragged around the edges!"

Curved ball thrown in my direction!! The other link is one from jagsparesinternational who do a shroud for £47.

Now you've said it helps with cooling I'm going to get one even though mine runs fine. I'll take some photos and post later today.

Thanks for all your help

UPDATE - The fibreglass shroud (only fitted to 3.4 & 3.8 models) is part number C24965. David Manners are currently out of stock but Martin Robey can supply at around £70 GBP.

 

So......

I need to establish what rad I have, take some careful measurements and see what fits. What could possibly go wrong!

 

Few pics of existing set up and expansion tank.



Not sur

e if anyone can tell what radiator I've got from these

 

I also have a 1968 240. I replaced the generator with an alternator but kept the original adjuster and pulley. So the spacer is originally there.

 

Hi Jim. Thanks for that. Mine looked so wrong on that furthest point. Makes sense to have it on the bolt you've shown. Is it possible to have a few photos of your radiator showing the shroud (if you have one) and the in and out hose connections. I'm trying to confirm what radiator I have. I've posted a few photos. Many thanks
Ron

 

Looking at your photos, your radiator looks just like mine, no shroud, long lever connecting to the drain spout at the bottom.
