I measured my anti freeze density in my car today and the readings were off the scale. The guy i was with (mechanic) said it looked like I had neat undiluted antifreeze in my radiator. The scary thing is that my coolant was done at a subaru dealer at my last service.

Do i have a bone to pick with my dealer do you think?

 

when you say read off the scale what do you mean? I had mine tested and come in at -45. Should keep me safe for winter

 

mine was around -60, but its hard to tell as the scale only went up to -50 so i dont know the accuracy after that.

 

If I recall correctly anything slightly above 50:50 will appear "off the scale"

Depending on what you use to measure it with obviously

 

At least you know they have changed it and the mix is strong, dont really want to pay for water dou you??!!! When I change antifreeze/coolant, the weakest mix is apparently about 25%, the average sort of anywhere between 25 and 45% but I always use a 50%mix.

 

sorry to go off topic eagle, but how much did your dealer charge to change your coolant? want mine done next service and could do with knowing the approx price

cheers (and bttt!)

 

going to use some 'Mobil 1' coolant from halfords and water wetter on my next coolant change using 50/50mix.
