Is the Genuine Volvo Coolant: IAT, OAT, HOAT, or SI-OAT?

G48 SI-OAT

My light comes on only when hard braking, stating that the coolant is low. When i checked it, its about 1 finger below the MIN. If I by this product do I need to dilute it or can I just top off? Thank you

This Volvo coolant is concentrated and must be mixed with distilled water.

I understand this is a concentrated antifreeze, what's the dilution ratio? My 2005 Volvo S80 reads that it needs 9.5 qts (http://new.volvocars.com/ownersdocs/2005/2005_s80/05s80_09.htm#pg147), how many of these would I need to buy to dilute to 9qt?

For a drain and fill you'll need 1 gallon of antifreeze and 1 gallon of distilled water.

Hello, I have a 2002 volvo s40 turbo charged and I am looking for the correct coolant to use because I have orange coolant currently and I am just trying to use the right one

P/n 31439821 is the correct p/n for your vehicle.

I have about 3 liters left of concentrated Volvo original coolant(P/N 31338284) that I purchased from FCP few years ago for engine coolant replacement. Can I mix together Volvo coolant that you currently sell(P/N 31439821) with the old one(P/N 31338284)?

While both coolants are compatible, we recommend not to mix them.

Is this coolant a concentrate formula that need to be diluted with distilled water?

This coolant is Concentrated, Must be mixed with distilled water

I had to drain my expansion tank to replace it. Can I use this coolant which is blue-green to top off my coolant which currently has the green Volvo coolant? Alternatively, can I just reuse the coolant I drained out of the expansion tank?

Coolant should be replaced every 3 years. Also, You can use this coolant as Volvo superseded the green coolant by p/n 31439821 to replace all previous coolants.
