Hey two posts in one day! Wow

I just filled up my washer bottle and noticed my coolant looks as if it boiling I do have a video but the app won't let me post it.

Any ideas?

it could be the pump is still pumping coolant round the engine to cool after a drive if so its normal. i'm sure someone will come along an correct me but i think it also prevents turbo damage from excessive heat after engine switch off

Funnily enough I had this after a short 10-15 minute driver around some twisty roads up in the hills - parked on a carpark to look at some views and could hear some bubbling. Looked and it was the COOLANT bubbling but I believe it was still being pushed around to cool off I guess! (bubbling from where the pipe joines the box)

I'd be concerned about brake fluid boiling...it implies there's water in it - which is bad!!

The coolant shouldn't be boiling. I don't know if your can has as an electric water pump or belt driven. If it's electric then it might just be a cool down cycle. If it's belt driven then it requires the engine to be running

I guess since the bubbles were coming from where the black hose joins the bottom of the plastic container, that it was still pushing brake fluid back around or something similar? Since the bubbles were rising from the hose. I had a look in and the liquid itself wasn't bubbling elsewhere, just from the hose - so I guess it was just still moving around .Was quite loud though but not heard it before.

That's the coolant, I hope you haven't been topping it up with brake fluid... :tongue: 

 

Coolant shouldn't boil as it's pressurised, but the movement from the coolant pump may make it look that way?  I'd be interested to see the video.

Christ did I say brake fluid? :wallbash:I've had a long weekend off and today is my Monday.... 

That needs an edit right away! :surprise::sadwalk:

Normal after a run if pcm thinkd it needs coolant flowing round turbo to cool it down

The pipe shown is the feed back to the coolant reservoir from the turbo. I think its quite normal to have some flow back for a while whilst the engine cools.

Cheers! I thought it would be but just threw mine in there since I saw somebody with the same query! Just never heard it so loud before, but think its because it's probably the first time I've sat in my car for 5 minutes with the radio off after a drive!
