I don't know what coolant Veekay has but I was intending to top it up with OAT (Organic Acid Technology) based coolant. Is there a problem doing that please?

I thought 75s used the pink OAT didn't they? It's the non-OAT that can be an issue.

Well, the stuff in there at the moment certainly isn't pink

There have been discussions on the OC about coolant and that OAT which we all use I would think can and in some cases as been blamed for the deterioration or failure of the O-rings seal in the water pumps, and the O-rings on the V6 thermostats, some have taken to using the purple coolant instead, but fingers crossed I have used OAT in both the tourer and the MGZT and I did how ever have to change the thermostat on the V6 after only 18 months when I took it out it did seem that the O-rings were a little perished, I have since used different O-rings but stuck with the OAT, cheers Arctic.

If any member intends to try this I would make double sure it is ok first
