Sandals Posted August 31, 2016 Share Posted August 31, 2016 Welcome to the club!! Fingers crossed your head gasket isn't on it's way out... When was the coolant last changed? Could just be the header tank deteriorating and making a mess of your coolant Quote Link to comment Share on other sites More sharing options...

I would change the coolant, do a few flushes.... new coolant in and see if it scums up again Quote Link to comment Share on other sites More sharing options...
stuartie Posted August 31, 2016 Share Posted August 31, 2016 Hello and welcome as sandy has said it could just be something as simple as small bits of rust etc in the coolant making it turn that colour if its not been changed in a while my v1 classic was the same when i got it but draining the system and flushing it out a few times with clean water made everything better Quote Link to comment Share on other sites More sharing options...
MJP02 Posted August 31, 2016 Share Posted August 31, 2016 Sounds like a lack of coolant change, more than likely rust and deposits gathering, people before could just use tap water as coolant, best bet is dont use engine flushes as they take out weak gaskets, but empty system, fill it with water and run for 10 mins, cool it down, drain it and fill with proper coolant, give it a few hundred miles then drain and swap, hopefully this will have cleared any coolant abuse Quote Link to comment Share on other sites More sharing options...

MJP02 Posted September 1, 2016 Share Posted September 1, 2016 Jack the car up, put on stands, drivers side of the radiator (bottom) there should be a drain plug, get big container to catch old stuff, make sure its cool, take off expansion tank cap then undo the drain plug. once its all out put plug back in and refill.

Nearly as close as mine, not bragging lol. Only thing I would do is after the refill go for a local run and make sure you don't have any locks in the system. I did with mine recently. Car gets up to temp stays for a short while then jumps up quick. Always a bonus to find an easy non expensive solution. Hope it keeps going strong. Let us know how you go.

Mr B Posted September 1, 2016 Share Posted September 1, 2016 Sounds likely just generals deposits built up as description doesn't sound overly worrying. Who knows when coolant last done or what junk been in it, leak inhibitors inc subaru's magic one makes right mess in expansion tanks over time . Good flush, expansion bottle clean & refill with good coolant should do job . Do check for leaks after as things like waterpump if old can start leaking after a proper flush, also if leak additive been in it the cause may not of been resolved so keep eye on things for few days ...
