<< 1).Is there a better brand of antifreeze to use in our cars. Not asking
for
personal preference of brands but more like compatibility.
Non Brit car specific:
For a cast iron engine I see no problem with any name brand antifreeze. For
a aluminum headed engine, a low phosphate or low silicate formula might be
worth a look as VW speced this stuff in the late 80's early 90's. I have put
regular name brand stuff in my customers and my cars for years with no
problems. The key is to change it every 2 years or so. The long life stuff
might not be worth the extra cost and I am unsure about the enviro friendly
"Sierra" brand AF.
>> 2) What mixture>>
60% AF to 40% water is just fine, this gives some mixture strength so you can
top off with water from time to time. Get much over 70% AF and cooling will
suffer as plain water is a better conductor of heat than AF. AF has a
advantage of a higher boiling point than water. If you live in a area with
high mineral content in the water, use distilled water if the car is a long
term keeper. I tend to put in regular water around these parts. ( As a side
note, use distilled water in your battery, using high iron water will shorten
it's life )
3) How should I dispose of old antifreeze.
>>
"Check Local Laws" For the most part, dumping it in a sanitary city sewer
system is the way to go. They can handle this kind of stuff. Dumping it on
the ground, in a storm sewer or in a septic system is a no no.
Some garages, oil change places, parts stores will take the stuff as a public
service.
