Morris Minor Owners Club

well folks ive taken the plunge and changed to coolant to evans classic cool .it is expensive but if it lasts the time they say it will it will be a good investment .

Well it is (or was) your money. I hope that you fitted new radistor, water pump, and hoses - would not want to think of all that lovly water draining away due to a failed component.

there been loads of discussion on the scimitar forum re this,the main benifit being a higher boiling point,(Scimitars are well known to overheat)But surely not for minors which run at too low a temp,far to expensive for me,for virtually no gain.

Did you visit the stand at the NEC?

i have been mulling it over for a few years ,and yes all my cooling system is under 2 years old ,and i did see them on the stand .it is the higher boiling point and no corrosion that attracted me .at the end of the day its my choice and i am happy with my decision .

If the engine is over heating, I'm thinking it will just take longer to reach the new boiling point and have possibly done more damage than with using water. Treating the symptoms rather than the cause? Maybe I'm looking at it the wrong way.

the engine runs on a cold day at 60 degrees c and a hot day 70 to 80 but its when i am stuck in traffic is when its a problem .everything on the cooling system is 2 years old and less i am hoping that this works because there is not a lot more i can do to keep the engine cool . i have had 2 head gasket failures in 2 years .its belt and braces i am afraid .

My thoughts were your engine will get just as hot but the coolant won't boil. If I'm right I can't see it helping the head gasket problems. However I could be wrong.

At this time of year I'd be more concerned about thee freezing temperature. I have to change my stat summer /winter

well,allthough you say all system is renewed,there must be a problem somewhere,moggies do not overheat with the standard rad ,pump and fan fitted all in good order,in fact even in summer with the fan removed they will only overheat when stuck for long periods with the engine running.Have you flushed it out,maybe slited up engine waterways.2 Head G failures in 2 years ,Iv'e not had one go on my splitty ,the only change being at a decoke 10 years ago.

Saw this at the NEC, not sold on it.....

I have thought about it for my elan mainly for the corrosion resistance and resistance to boiling locally within the cylinder head, which is a factor in head cracks etc, for a basic old lump like the all iron A series the benefits would be marginal.

roy bmc eccoss must be on holiday again,or he would be on shouting Snake oil wonder if he could use it in his steam engines

Dale,
It's your car car and your money I have read good reports about it and have considered using it myself. The anti corrosion side is the thing that appeals to me. I would as Kennet says though check for blockages in the waterways as you have had 2 head gaskets go so quickly. I don't think just raising the boiling point of the cooling system will be the overheating cure.

Regular anti-freeze has plenty of anti corrosion for a Minor, cast iron isn't especially prone to it anyway.
The reason the system is pressurised is to raise the boiling point, it won't boil at 100C.

the advantage of a raised boiling point is better conduction of heat way from hot spots,by keeping H2O as a liquid ,steam is a much poorer heat conductor ,and it doesn't flow

Guys, I understand the principle of how how the system raises the boiling point with the radiatior cap. I was trying to say that if you are stood in traffic and the car is overheating surely using a fluid that won't boil until 180 deg will only create more possible issues?

aS said a STANDARD moggie will not overheat,unless the fan has been taken off,I could leave mine ticking over all day untill it ran out of petrol and it would Not overheat, if it is there is something wrong in the system.

Has it done any good? I suppose the answer will show in the temp gauge reading.

so far so good ,its the no corrosion on the sysrem that sold me .
