I'm doing a fill with PentoFrost sf (without silicates formerly g12) and distilled h2o

■ Audi (after 06/1996 up to 2005); Spec. TL 744 F
■ Jaguar (1997 on)
■ Land Rover Freelander, Discovery, Defender (1998 on)
■ Porsche Boxster, 911, Cayman & Cayenne (1996 on)
■ Saab (2001 on)
■ Volkswagen(after06/1996upto2005);Spec.TL744F

Seeing as I fill the audi and porsche with it..I dont see a single indication suggesting I need to stick with dex cool, the problem being mixing the two...wheres the easiest place to drain the block for a complete flush?

so none of you wise asses know how to drain the block? I'm not askin how to drain the rad. But thanks, chuckle patch kids. I also always dispose of fluids in an EPA compliant manner as you should too.

There is a block drain on each side, they have square heads. Look in the shop manual for the locations as they are really hard to find and get to especially the passenger side.

you have to take the plugs out on the block, something I didnt risk.

I undid the lower radiator hose, let it dump. Then ran truck with water running through system until everything was clear coming out.

On the back of the block. IIRC they are 1/2in square stud...

If you lay under either cat, they are straight up.

G12 is good stuff, don't get me started on G11 the blue stuff. I've thought about switching everything to G12, but dexcool is cheap and available everywhere. Though right now my Disco isn't leaking any coolant.

My Dad is old school, and when he flushes a car it takes days, especially if you are switching types. Drain and fill with water and a commercial cleaner, drive it a day then pull the hose and drain everything you can. Fill with water drive a day then drain. My VW needed four flushes to get the old stuff out. The way my dad explained it the cleaner/old antifreeze feels slick between your fingers, get doing fill drive and drains until it feels like water, no slipperyness.

When you get to the final fill part, drain what you can then fill with half/half G12 and distilled water.

I know G12 is suppossed to last "forever" but I change or flush all of my cars every two years, but the Disco was on a continuous drip and fill until recently. Seen too many nasty radiators and colling systems to let it go much longer.

Anti-freeze
Use Havoline Extended Life Coolant (XLC), or any
ethylene glycol based anti-freeze (containing no
methanol) with only Organic Acid Technology
corrosion inhibitors, to protect the cooling system
CAUTION: No other anti-freeze should be used
with Havoline Extended Life Coolant.

there you go gem. p107 in the rave.

make sure you use distilled water too. THAT is the key to limiting leaks and issues long term from what I have seen.

Thanks kyle.

so my point to the dweb world is:

no where in rave does it say use dexcool. it says use OAT

not HOAT or IAT

OAT is Havoline® XLC(avail formerly across pond only), GM's Dex-Cool® (also manufactured by Texaco) and VW's G12 made by pentosin, who maketh the green steering fluid that goes in our cars, the pink antifreeze. they make a great super dot4
I'm on now, and I'm using their 5w-40 in my audi porsche and LR(that or the Elf/total oil). Its also what i suspect factory fill of our tranny is. just like the LR diff oil is the SAF-xj(so is bmw and porsche diff factory fluids)

I think using crap like royal purple, redline, dexcool is where we all go wrong. Its british stick with euro stuff

It makes no sense to put a GM product instead of what comes from the factory. Go buy LR brand coolant and go buy g12. same.

To Quote my manual:

"Use Havoline Extended Life Coolant (XLC), or any ethylene glycol based anti-freeze (containing no methanol) with only Organic Acid Technology (OAT) corrosion inhibitors"

Halvoline XLC is a licensed Dexcool. Personally I prefer green changed often or HOATs

Ahhh...The Gem we know and love. Translation of above:

"I'm better than everyone. I buy really expensive parts (read: Because, I've got more money than you.). Comparatively, everything else is shit, no matter what it's done in the past or how really useful this new thing is. I spent lots of money, so it's the best (or really Heavy Duty)".
:D

This is rich...what's in your engine bay? A BMW power plant?

-----------------------------------------------------------------------------------------------------------------

Back to your question about changing the coolant:

Drain old coolant. Add distilled H2O. Run engine at temp (with heater open) for 10-15 minutes. Let cool. Drain and repeat until clear water runs out (took me ~3X to get fairly clear).

Determine total capacity of cooling system (see owners manual). Add 1/2 of that capacity of 100% anti-freeze. Remove air from system and run engine at temp (with heater open) for 15 min. Let cool. Check density (specific gravity) of the now mixed coolant and add H2O or antifreeze as necessary, and top off with 50/50 AF/H2O.

Got her done, back to pink, the way she was when I bought her, and no has nothing to do with income. Its British. It didnt come from mopar with dexcool in it. Did it now. Go look in the engine bay of any rover, and find where it ships from factory with GM fluids?

No,
It doesnt take alot of brains to figure if I took pink out, putting orange is just what we do here in the states. Logically pink out, pink in. Thats what I did. if you feel threatened by my logic, check your own.

I would sooner use a formulation by Texaco over GM. that DOES make me smarter doesnt it...google lawsuits Havoline XLC and Google lawsuits G12. Then google dexcool litigation. See for yourself, if you cant tell the difference between pink and orange, yes
I'm still an asshole-arrogant as ever. Just not a color blind one!

dwebbers will use dexcool, thats cool
g12 is german.. therefore, HD..

pink out pink in, simple for me

ACE/PAS fluid is Texaco Cold Climate PAS fluid. Same as GM High Performance PAS fluid p/n 12345866 16oz and 12345867 for 32oz. comes in Vettes and the caddy XLR.

I wish there was some alternative available down here. only thing I have ever seen is store brand non syn PAS fluid....

If its green and mineral based like CHF11s and the OE ACE fluid I get from LR stealership, then youre right its the same thing. Keyword, mineral. Agaibn, I rather stick with the EU formulation. I like texaco fluids, so cool, so long as its the same chemically. Both green, rite? I like color consistency. I dont think the engineers added these colors to make it pretty under my hood..

Look at Dexcools MSDS, it shows 96% ethylene glycol
G12 is 85%. yes there is 10 % other stuff in g12, thats missing from the GM formulation, agreed they are both silicate free OATs..

SOurce me the havoline, or source me the g12, but i rather stick to pentosin banded EU formulations whenever possible. No one with a Porsche or a M3 or a Audi s4 and yes I frequent all those forums too, goes and takes a foreign car and puts cheap bastard fluids then wonders why the head gaskets blow as soon as the coolant ages...

its not CHF11s, but it is only a semi synthetic. I think the pentosin has some detergent in it (from my porsche days...) cant remember though.

edit, they sell halvoline dexcool here just about everywhere.

and ya, gm and rover is Texaco fluid. same greenish stuff.

and distilled water makes a big difference with the coolant. noone does this.
