Hi Guys,
I have a 2002 Discovery TD5 , only had it about a month and after a very cold night last night I thought I'd better check the anti freeze , my tester showed that its only safe up to about -5 so I feel it needs to be a stronger mix, is it possible just to add some pure anti freeze by letting some water out the system instead of draining the full engine , also what type of anti freeze should I use , I read so many different views.
Cheers
Donald
