Before the cold weather really sets in in I need to change the coolant in the Wife's 300 TDI.

What do people recomend for use in the 300 TDI, in my V8 P38 use pink OAT based coolant either from Comma or Halfords, in fact use the same stuff in my VW track day car.

Is the pink OAT stuff ok in a 300 TDI ?

Jamie.

Have the pink stuff form halfords in my disco 2 td5 and have had no problems.
