I need to change the thermostat on the KJ, but I'm struggling to find the correct antifreeze anywhere.
Does anyone know a supplier for the HOAT type, or do people just use the OAT one instead?

Cheers 

Blimey it's not cheap is it.  I was going to give it a flush and replace it all.  I might drop one of the sellers a line and see if they do a bigger bottle

The simple answer is HOAT is backwards compatible with old ethylene glycol where OAT isn't! It's all to do with the silicate mixing capabilities! I went on a very very boring course regarding coolants! if you put OAT in an old cast engine designed with ethylene glycol in mind it does rot rubber seals & joints (I do have personal experience of this) & if you put old type coolants in an all alloy engine even with distilled water they do fur up & don't stop alloy corrosion!
Hope this helps!

I use the Mobil HOAT version in my KJ 2.5 CRD with no problems..down to minus 25. But it's a shit load cheaper than you poor buggers are being slugged. A 5L bottle for me cost about 4 quid.

Comma G-05 is HOAT. Available in loads of places nowadays. I switched to it at my last flush/change when I did my water pump. It's the same price as the other Comma antifreeze types at my local car shop.

They have a stockist finder on their website. Look near the bottom for the postcode box...

so what goes in a 360 then? FFS I had no idea ya coudnt just shove any antifreeze in there

I've used Comma products for years and never had a problem. 

If you put your reg number in on their website it tells you what fluids to put in your motor - oils and antifreeze and your nearest stockist.

They also have a guarantee where they will come round to you and take a sample if you think their products have caused damage, I know that they probably have dozens of get out clauses in it, but I'd have thought they'd have been caught out long ago if they were producing crap.

Thanks for the info guys.  The Comma site has come up with a supplier that's only 2 miles away

and more to the point - does the price seem a lot bit for you

[craigderby]

I got a couple of bottles today.  With the distilled water I ended up spending over £40 on it
