Why is it so complicated?
Morgan say only use WSS 97B44D. Can only get WSS M97B44D from Ford. Is that different.
The coolant in the car it is orange coloured whereas the above is more “ greeney “ yellow. The general stuff from jayar car parts supposedly for fords is red.

Every Ford spec coolant seems to have the”M” included, including Ford Superplus which is what I will be using when I change mine this winter.. Colours are confusing but I think the spec is key.
Just looked in my handbook and the “M” is not shown, but it wouldn’t be the first time that I have found errors and omissions in it. Another Morgan “thing”!

+8 Rich. Yes I had seen that chart, but just adds confusion. 2011 Focus yellow but the yellow is not the spec. Orange seems close but the bottle I have is not really orange.

Cheaper to buy as concentrate and dilute 50/50.

Ignore the colour it's the spec that counts. Some coolants appear different colour in the bottle anyway.

It may change colour when you dilute it in water, distilled is best as tap water can be 'hard' (I save the water from our garage dehumidifier)

My knowledge of antifreeze technology is now a bit outdated but I did work in this area in the 90s.



Early glycol based formulations were either dyed with fluoroscene yellow or blue (forget the name of that dye) they are stabilised by a buffered formulation using borates. These are less stable as the corrosion inhibitors and stabiliser break down over time and the system needed flushing out and changing every few years.

Almost all "modern" formulations are based on organic ester technology (OAT) which is more stable over a longer period, these are generally coloured orange/red.

However there is no spec on the colour used (although it is a generally accepted industry standard) so you really have to go by the spec rather than the colour.

As long as you stick to one technology or the other you shouldn't incur major problems , but it is obviously better to stick to the exact spec if this is available.

The really important point is that you cannot mix the 2 technologies , as the stabiliser systems are very different , and the way they work is also different.

FWIW: The Ford one states it is good for up to 10 years whereas Comma says 5 years for theirs.

Well topped up with Ford one 50/50 using de-ionised water. Before a run you could see the new sitting on top of the old. It did change colour a little when adding the water, making it more orange.
Thanks for the replies. Interesting reading.

As your 4/4 is now 10 years old, have you considered totally renewing the coolant, or has it been done previously? I know there are some schools of thought out there that might say “fit and forget”, but although it will carry on cooling, might the anti corrosion properties diminish and consequently shorten life of rad and water pump, etc.?
