So what part do you not agree with? Putting pure coolant in is not a good idea, it needs to be mixed with water, which you actually concur with. How you get to 50/50 is entirely up to the person putting in the coolant. I was saying that you shouldn't put pure coolant into an engine, because although it is an anti-corrosive it only works at cooling the engine when mixed with water.

I'm sorry I must have misunderstood what you meant. I thought you were saying that it is not correct to put the undiluted anti-freeze in FIRST - but I'm now thinking that you were actually saying it's not good to run on pure 100% undiluted anti-freeze.

Thanks, I'm now doubting my exact mix so intend to pull the bottom rad hose, flush with water hose and refill starting with 5.5L of coolant. '95 300tdi es disco with aircon - presumably the capacity is 11L?

No idea of the capacity I'm afraid. But you can get a coolant concentration tester for very little money from any motor factors. A good investment I think (although I have 2 and I have never used either of them!).

I wouldn't use the blue antifreeze it's is rubbish and only last a couple of months before you have to replace it again I only use long life in any vehicle I work on well worth the extra money never had a problem in the last 12 years

Really? I have never heard of that before. You must have bought some really really poor stuff...

What I will add to this is that you need to make sure you get the right antifreeze for your engine. I don't think the more modern OAT based stuff is good for older engines.

OAT-style anti-freeze has been known to corrode aluminium engine parts.

On TD5 for example, the elbow on the front right side of the head head is a classic for this.

OAT? Hmm.. all I know is that I usually by blue stuff (MEG) from the local car factors...
