Hi, I am new to owning an XJ6 X351(new shape XJ) and have just discovered that I cannot use the coolant top-up that I have and used when I drove an X type!
I need to buy this orange coolant with part no. WSS-M97B44 Extended life coolant.

Amazon seems to sell this which is in fact a Ford product, but at the end of the number is a 'D', hence: WSS-M97B44-D.

Is this OK to use?

Regards

 

Google OAT Organic Acid Technology.
Use premix 50/50 or add distilled water to concentrate for 60/40 in colder climates.
Do not use tap water to dilute concentrate.
There are a limited number of manufacturers but many brands.
I prefer a national brand from a big-box store.

Opinions will vary.

Best regards,
