Milky coolant but clean oil and no overheating.. 2.0t

Samwell · Nov 25th, 2017, 19:10

Hi all

I started a different post the other day regarding opinions on the auto 2.0t. After now having got one, I got it home to notice the coolant had turned to milk..! Panicked of course, feel that I let myself down... BUT anyway. Of course, I immediately think headgasket as most might..

BUT i haven't found the oil to be different from what it should be, there's no loss in power, no white smoke, no overheating. Im getting it booked in at the garage, the Volvo specialist, but before I convince myself it's a headgasket thats gone, have any of you other 2.0t owners experienced the same thing? I am hoping that there must be some other explanation...

theres a chance youve cracked a liner, but youve most likely burst the oil side of the oil cooler. the oil pressure is higher than the coolant side so its pushing oil into coolant. not the end of the world, just get a new oil cooler, then get a small box of dishwasher tablets.

drop all you existing milkyness, fit the new oil cooler but dont fit the coolant lines to it, and join them with a piece of pipe. refill system with water. break up a dishwasher tablet and drop it into your header tank. run up to temp then drop coolant.

do this until youre getting pure water when you drop the coolant. dont fit the coolant lines back onto the oil cooler until youre getting pure water.

now add your coolant of choice

Umm, nasty picture size issue on my El-cheapo Android I pad!

Question for the OP, are you using real Volvo or Liqui Moly coolant ??

If the oil is OK (No mayo or coffee cream) and you are not getting a coolant loss or odd overflows, nothing much is wrong in my umble pinion.

Thanks Dunkin, that's a positive outlook that I'm hopefull for! It sounds like more time and equipment than I have to hand so I probably couldnt personally do it but I hope they will look at that side at the garage. I'll certainly mention it to them!

Sorry, Skyship, it's my fault and my lack of skills in knowing how to resize it. I have to say, I really don't know what's in there for coolant or oil for that matter... They could have filled it up with milk for all I know.

No oil loss, no coolant loss that I can tell of just now, but again, I've owned her for 24 hours, driven it once other than the test flight.

Little update... Ive managed to get access to an indoor workshop where I'm going to change the water, today. I've already got the right coolant and will flush the system until clear, then add the coolant, drive it a few days and see how it goes.

Will keep updated.

Another culprit could be the oil cooler. Fingers crossed nothing happens after you change the coolant.

i wouldnt waste your new coolant until you replace that weeping oil cooler and are sure youve sorted it. itll just do the same again and youll end up doing another cleanout

Could be corrosion. A coolant change is cheaper and easier.

Samwell · Nov 26th, 2017, 17:56

Well, here's an update.

Took all of the milk out, flushed it once, twice, filled it with clean clear water. Ran it until hot. Drained it, flushed it twice. Filled it with 50/50 mix. Drove it a few times. Level is settled at max line and the water is still blue, albeit a little cloudy but okish.

A little white smoke on start up but considering its 0 degrees here, nothing extreme. I'll keep an eye on it over the next few days and report back.
