Anti Freeze mixture

[sjgcpa]

What is the proper mixture of anti freeze to water for a 66 BJ8? I assume all anti freeze is created equal.

There is no single "proper mixture".

Anti freeze provides freeze protection, corrosion inhibiting, & water pump lubrication.

Although it raises boiling point, it has less thermal conductivity than water & gives less efficient cooling.

The standard 50-50 mix provides freeze protection to around -34 degrees F. If you are in a warmer climate something like 20% antifreeze could provide some freeze protection, corrosion inhibiting, water pump lubrication, & better cooling effeciency.

If you live in a climate that doesn't freeze, something like Red Line "Water Wetter" or other corrosion inhibitor/water pump lube additives could be used without anti freeze to provide the best possible cooling.

Although some newer cars use a non-Glycol based anti freeze, I would stick with the older traditional Glycol based products.

That's the best and most complete answer to your question you are ever likely to find (and the same thing I would've said /ubbthreads/images/graemlins/devilgrin.gif ).
