C70 mk2 - coolant in a 2.4i colour

[TheMajor]

Hi guys,

I have a 2008 C70 2.4i. I love the car a lot. I have a 300 mile drive each way coming up and it’s going to be tight time-wise and it’s to the start of our holiday and we will be getting married. I am keen this goes smoothly.

I checked all the fluids in the car today and noticed oil was a tad low, roped up. The screen-wash was low and topped up.

Now my coolant is just below or on the minimum line. I have no idea what coolant is in it and my local car shop didn’t want to recommend anything. It’s a orange colour, not red or pink.

Is this the Volvo coolant? I’m tempted to just top it up with deionised water (few 100ml). Any advice would be welcome?

It’s going in for a service in 2000 miles and I’m considering adding a system flush then. Thanks, Mike

Deionised water will be fine.

Thank you.

Hi,
Just something I was told, so I will stand corrected. FYI pink coolant supersedes the blue coolant but don't ever mix them together. Anyone more knowledgeable, please confirm or correct this info. Thanks.

That is corrosion , a brown colour not volvo coolant ..
I would advise some new volvo coolant , it is the best you will get anywhere as it has no change interval . It is blue/green colour and should stay crystal clean and bright for many years ( 31 years so far in my 343 ) It is also cheaper than halfords etc which has to be changed every 2 or 3 years . A 4 litre bottle should do it , flushing that brown stuff out with clean water is a great idea .

My coolant was an orangey/yellow colour when I bought my car last year, albeit clear with no obvious sludge or debris. A few weeks ago my EGR cooler was replaced by a dealer (involving a partial drain-down and coolant system refill, as itemised on the receipt) and the coolant is still the same colour with no hint of green/blue whatsoever... Are you sure that Volvo coolant is always green/blue?

100% sure , i have been working with it for the last 40 years :-)
what they did was just top up with a litre of the green/blue as that is what they loose doing the EGR cooler work , Volvo will not pay for more as it is warranty work .
best to change it at the next service .
