Getting majorly confused with Coolant types,

Last time I read about them on here the advice appeared to be:

Don't use the Blue Stuff as it damages Aluminium Engines
Best to use the Pink OAT stuff.

I've been reading this article about Rolls Royces and it seems to say the other way altogether stating that OAT coolant can cause overheating and blown headgaskets etc, could this be the reason why so many are going?

Use the blue stuff on the GEMS engines and the Pink stuff on the BMW diesel and the Thor engines.

Hi,
Does the BMW engine use OAT tpe coolant?

I never understood the HUGE insistance on folks to choose their coolant based on GEMS or Bosch. It is the same dang engine with a modified intake. Rolls Royce pulled the same thing when the latest and greatest orange stuff came out. Never mind they had been running the same basic 411CID engine from the early 60's until just a few years ago.

Flush your system through a couple of heating cycles with the garden hose and fill with whatever coolant is available in your area using the proper mix for your climate. Our rigs began life, as did all of the years of Classics and the Buicks before them, with green blood running through them. There is nothing wrong with green juice. If you want to go for the newer spec extended life OAT stuff, go right ahead. I think Havoline XLC was the actual spec for Bosch systems. Just don't mix them. In our rigs it really does not matter. 8-|=

I use the tears from baby seals for coolant.

Is the gator also related?
He's a pocket relative and hangs around all the time. Kind of a over the shoulder cousin.
But doesn't get under one's feet? ;)

Hi,

After much search, I used 'WURTH' green colour coolant (thanks to GAYAN).
The bottle does not say it's OAT or otherwise but it instructs to change coolant every 2 yrs.
Hence I assumed that it's a non OAT type suitable for BMW diesel engine.
I've run about 500km already and no issues so far. :thumb:

just did a full service and had been a tad 'worried' that the stuff in the garage I'd been chucking in might actually cause damage - on the basis the engine (1997 4.0) has been around since Adam was a lad thought what I use in my Scimitar would do just dandy in the RR - checked RAVE and the owners handbook and the RED stuff (more orange to me but it says RED on the container) I'm using is

'Engine cooling system Use an ethylene glycol based anti-freeze (containing no methanol) with non-phosphate corrosion inhibitors suitable for use in aluminium engines to ensure the protection of the cooling system against frost and corrosion in all seasons.'

So apart from the issues of finding a croc in East Yorkshire never mind the swamp water (mind you the Humber river might just give up some swamp life!) I'll stick with orangey/red coolant with the right bits in it!

U r right. but the dealer has only OAT stuff suitable for newer RR's. Also, he will sell it , even to be used in a Series III LR with copper radiator. U can guess who benefits.

Normal green stuff, and never had a single issue in over 210k miles....
You would NEVER catch me going to the dealer for regular old antifreeze. These are 30+yr old Buick pushrod V8's, not a magnesium, dry sump'd Lambo motor :lol:

Well if you are that unsure then like I said just wander off to the dealer and get the original LR stuffs. I also have a 1997 Alfa Romeo and I am using the new OAT stuff without any problems, more than 5 years now. As far as I am concerned, the newer OAT stuff should replace the older glycol based coolants without any issues as long as you don't mix the two. This means a through flush before refilling with OAT. My p38 has also been running OAT for almost 2 years with no issues.

Seems like the only issue I have is being banned by the Admin this board for complaining of a vendor.......only because I never pay money to use this forum. :lol: :lol: :lol:

SO BAN ME AGAIN NAH NAH NAH.........
