mix % of water-coolant?

[twvenezuela]

Wath is the recomended percentage for mix water-coolat?

Car:
Renault Twingo, engine D7F, year 2000, manual trans.

Check the coolant recommendations. Normally it is 50/50 ratio except in the coldest locations.

50-50 water-antifreeze. If cooling is still an issue, you can go up to 70-30 water-antifreeze. Never run just pure water.

Or pure coolant.

Puro coolant isn´t bad for the engine?

This is OK for coolant system?

thanks

Pure antifreeze concentrate will freeze at a warmer temperature than a 50% antifreeze/50% water solution. Pure antifreeze concentrate also has less ability to exchange heat than when mixed with water. This can seem contradictory because while the engine is actually operating too hot, the temperature gauge sensor is reporting a contradictorally cooler temperature in error. (Evans coolant is specifically formulated to be used without water, though.) Antifreeze should NEVER be diluted to lower than 40% concentration unless corrosion is the desired ultimate result.

I forgot to quote in my previous post above.

50/50. You don't even have to measure it out because Peak and Prestone make a pre-dilluted 50/50 antifreeze. I personally use the Prestone version.
