I am currently on vacation in Mallorca, Spain. The car (Citroën C4 Picasso running on diesel) that I am driving is running low on coolant. I went to a gas station to buy a bottle of coolant for the car. On the bottle there is a label that reads "USO DIRECTO" and "10%" (I have attached a photo of the label). "USO DIRECTO" means "direct use" according to Google Translate. What does the 10% mean? (Normally you have to mix 50% coolant with 50% water).

enter image description here

  • Does the bottle have any directions on it or is that the only label? – kyle_engineer Aug 8 '17 at 22:52
  • That is the only label on the bottle. No directions on it. – thd Aug 8 '17 at 22:53
  • Ok. I'll see what I can dig up from that. Also, welcome to the stack! :) – kyle_engineer Aug 8 '17 at 23:12
  • That was kinda hard to find. :) – kyle_engineer Aug 8 '17 at 23:31

OKAY! So I found the manufacturer's instruction page!

Under the heading


They provide a "general information" section and a "directions for use" section. Based on Google Translate it says:

Being a product formulated for this temperature should be used pure, not recommending its dilution. Insert directly into the circuit by the expansion vessel, or in the radiator, which has previously been emptied, it is advisable before filling, carry out a cleaning to drag the dirt and barrel that might exist in the circuit.

I'm not 100% trusting of Google, so you can still ask someone to translate if possible.

  • Excellent find! +1 – Pᴀᴜʟsᴛᴇʀ2 Aug 9 '17 at 0:11
  • Thanks kyle_engineer. I really appreciate your helpfulness. – thd Aug 9 '17 at 7:26
  • @thd no worries. :) happy to be helpful. – kyle_engineer Aug 9 '17 at 16:04

The two words "uso directo" means it is already mixed for instant use - seen just above the 10% on the label. A pre-mixed product.

The 10% is its strength so a summer / high temperature mix - Spain is a warm country etc, Winter mixes will be a higher percentage.

  • I was thinking that too but I was not sure. However, it is good to see someone else interpret the label the same way as I do. – thd Aug 9 '17 at 7:38
