I was having a chat to my mechanic a while back and he mentioned he wasn't that keen on long life coolant as it tends to crystalise over time.
I wonder if there's any correlation between the use of long life coolant and ZF failures through coolant ingress ? Is he just trying to get more coolant changes out of customers or is he on to something ? I'm inclined towards sticking with the regular green coolant but its a curious thing, I have both the Australian and N.Z. service manuals for my car and Ford Aust recommend coolant change every 3 years and Ford N.Z. recommend it every 2 years. I would have thought they would have been singing off the same song sheet ? Last edited by Rodge; 07-09-2012 at 08:20 AM. |

Different climate conditions is why the years are different.

The coolant does not crystalise in the cooling system, only does that if there is a leak and coolant dries leaving the crystalised corrosion inhibitors. Usually look like fine dry salt. The coolant just evaporates.
