Antifreeze...

Postby schurch » Tue 15.11.2005, 13:04

I can't find anything saying I need anything special int he antifreeze department for the elan, but thought I might ask anyway?

Anything I should no before I top up? Any recommendations?

I went to my motor factors and they had a list of recommended antifreezes. For the Elan it was Comma Green (which is actually blue :? - go figure). It must be changed regularly to stop corrosion. Oh, and if you mix different antifreezes you might get severe sludging. If you don't know what is in there it's probably best to drain, rinse/flush with distilled water and start over.

Sounds like good advice. Is there a 'how to drain the collant' section, with simple Noddy-can't-go-wrong instructions, somewhere?

On a UK car, it's easiest to drain by removing the bottom hose, and don't forget the air bleed plug under the nearside headlamp pod (do not shear it off by using excessive force).

Be carefull

At least on the North American cars there is a drain that makes things easy, just be warned that it doesn't take much effort to break it. To compound the problem it is a Lotus specific part. Guess what happend to me the first time I changed the the antifreeze.

Another suggestion. Use distilled water. The tap water in our area has a great deal of salt so a lot of auto enthusiasts use this trick.

If your car has been serviced by a franchised dealer, I believe that they all use Mobil (red in colour; yet another variation!!). The label proudly boasts that they are recommended by Porsche, Audi etc....

I recently had to top up over here, and went for the Esso equivelant which had the same "recommended by" list....it's no doubt the same stuff with a different brand, as Mobil isn't available over here.

In any event, if in doubt the advice to flush out and start again is sound.

i would like to substitute the water on my cooling system.
It´s a bit rusty, is it a big problem? on the exit of the engine there are some rusty steel tubes, should I be woried?how to remove it?

How do you use distilled water? do you fill the tank and then add some antifrize? or do you buy the mixture already made?

Distilled water use

Postby DeanG » Sun 04.12.2005, 17:35

When mixing up a 50%-50% mix of water and antifreeze I just use distilled water (available in the grocery stores). It’s a bit messy, or maybe its me that is messy. Anyway; I store the leftover mixture, labeled with a big bold 50% in the original container for topping up.

Sorry for the delay, I went from dialup to cable. It took me a while to get back going.

Hi all - can't find anything current concerning recommended antifreeze. I've read we should all be using IAT-based coolant... not OAT. IAT is better for older cars (pre-mid 90s..ish).. all to do with the corrsion that we know about. Any views?.. anyone got a good IAT brand worth looking at... or is this nothing really to worry about? cheers M.

Mike,

I stand to be corrected on the different brands of ethylene/glycol (blue) stuff - but my understanding is that the chemistry is very basic - just alcohol/water and a coloured dye (plus nasty taste!) added. I think that they are all pretty similar, and I just buy whatever I can find in a 5L container whenever I run low....

..... that said, I know that for the VW I *have* to use specific (purple) stuff, and the Astra uses the 'standard' pink OAT stuff.... so there may be more differences between the blue ones than I am aware of.....

..... but, whatever you do, don't use pink stuff in an older car as it will attack/eat/corrode some of the other bits in the coolant system.

Just the one now, but this one's mine! - and it will be finished eventually.....

I go to my local motor factors and buy whatever blue stuff they have in stock. I usually buy 5L conc. and dilute it to 40% which is good down to -25C (occasionally for a few days or more we can get down to -20C or so in Scotland :shock: )

I change my A/F every 2 years which helps prevent any corrosion and build up with sludge. Never had any problems with the coolant systems in any of my vehicles

I posted this previously but it is an interesting read:
It is an article from Road and Track Magazine:
Antifreeze.pdf


Dave: I know this disagrees with your observations, but my friend's shop did a lot of intake manifold replacements because of the OAT antifreeze.
It is not an old wife's tale, Red/Orange antifreeze really doesn't work well in cars not designed for it and it is highly corrosive.

................and if you do shear it then an M100 wheel nut will keep the water in until you can find a replacement. :shock: Top tip if you're on a road trip somewhere! :lol:

John,
The link you posted isn't accessible from the UK...

.... but I can guess at what it says - and i agree! I worded my reply very badly above, and having re-read it it looked like i was saying that you can use anything....now edited to say that you can use any BLUE stuff (ethylene/glycol), but not the OAT technology stuff :oops: - I was trying to suggest that there is little or no difference between brands of blue stuff. (AFAIK).
