Replacing engine coolant.

So armed with this info I ordered 5l of comma xstream G30 as according to commas website blurb it is both OAT and ethylene glycol based.

The engine internals didn't ever change on the TD27TI I've always been told that the green protects these lumps better as the glycol levels are a lot higher in that.

I'll only ever use green and my temp guage never creeps even when towing and still a good colour, had a test done on mine recently and tester said was good down to just past -20 so I'm happy

Well maybe the 2.7 Nissan engine is not fussy as my expansion tank has a pink tinge and it would have last been changed when I had a gold (cost an arm and a leg) service from a Nissan dealer six years ago.

Also found this,

So I think as above not fussy which would not surprise me with this engine.

I have always used the pink/red as the corrosion proofers are better for multy metal engines, Cast Iron,Ali, Copper, Steel, Brass, all of which are present on a 2.7 TDi, Rick

You've had more experience than me Rick I remember pages and pages of debate about this somewhere in the past, can't remember what the general consensus was apart from the fact that it's much harder to find the green stuff as most motor factors were telling me it was being phased out due to the high glycol levels which were bad for the environment yada yada

I know I have to pay premium whenever I buy it compared to the pink stuff.

Some more reading here, jury still seems out and opinions divided but I know I'll only ever use green, have googled this subject more than I care to admit but have heard that the OAT inhibitors in the red stuff isn't the best with these engines.

Seems it's a 50/50 split here between Red or Green
