Handy travel Size Great product, Value for Money..
Does what it says on the bottle. Mix with water, equals coolant.
good value for money, Just pour into radiator and add water.....simple!
Instructions can be weak. It still may be too early to really tell.
Small container easy to transport just add water when ur ready
did as bottle says. still no issues. will update in a few months if still worth it
good value best way to buy coolant no waste with big bottle
It's good product worthy to use every 15,000 kilometer or more flash clean the radiator add penrite use with guide directed on the bottle .
