Hi, there
I just bought a used 2002 S60. This morning is pretty cold,somewhere around 36 degrees. Just after I start the car, the message shows on " low coolant, check the engine". After fully heat up, the message goes away. I am wondering if I need to add some coolant to it. I read the manual and it states two kinds of coolant can not be mixed, I am not sure what was previously put in there. Should I just drain the coolant and put all new in there? Please advise. thanks a lot for your time and help.

 

You can top it up with a 50/50 green coolant mix. Or just add a slight bit of water to it.

 

Thank you for the fast response. You are the best

 

No problem glad I can be of help.

 

one more question for you here, I just happen to find 1L concentrated coolantin my storage which is at least 4 years old. It was opened before but sealed after use. May I just add water using 50/50 to the Volvo? thanks

 

That should be fine.
