Overheating issue [updated: pictures]

[bass_straitener]

Get a new OEM radiator cap and report back.

Having lots of trouble finding the part number for OEM genuine one, any ideas where to get them?

Ring up Subaru and give them your VIN and they will tell you if they have a cap in stock.

Same applies if you ring Makin & Luby.

You're a legend. Makin & Luby have one for 22 dollars, going to pick one up in my lunch break. Wouldn't deliver to my work because it's not a workshop haha

Great! Could be the cheapest fix ever. Fingeeez crossed..

Got the cap, will have to wait until tonight to put it on.

Just out of curiosity, what would the chances be it could be the A/T transmission? It seems that in 'manual' (tiptronic?) mode it doesn't get hot as fast?

EDIT: Just thought about it more - that makes a lot of sense. When I was driving the car to 'get the temps up' after I got it back, it was in manual mode so I could rev it out more (= more stress/heat?), then, once finished I put it back to Auto mode for the drive home and this is when I discovered the temps started rising?!?!?

Cap has made no difference, although car was still warm when I left work (strange?)
Maybe in morning will be a different story.

Any more ideas before I take it back to Mechanic I can try myself?

I am going to attempt to bleed the coolant on Tuesday, not that I think there is air in there any more (was a gushing noise on car start before mechanic had the car)

Thanks Matt,

Do I run the log while it's idle or during a pull or how exactly? Just so long as it's above 97?

Even stationary and rev the engine while car is warm will be fine. IF it gets to 97 degrees and the AF#1 correction is solidly in the negatives, then that is headgasket

FBKC and FLKC will show up in Knock_Correction_Advance(degrees) and Learned_Ignition_Timing(degrees)

That gushing noise is the noise that I get/got that had me started on the track of my head gasket.

On a hot/warm start I would get that bubbling/gushing noise in behind the dash. I found I had a leaking top radiator hose . Top and bottom where replaced and new coolant and bled, thermostat checked for correct function=all good. No gushing noise.... Hurray!!! Fixed..... Not!!

3 or 4 days later on a hot start... Boom gushing again.!!

Bled again and left for 30-40 min with multiple heat cycles , fans switching on and off etc.... All good.

1 week later... Hot start and boom gushing again.!!!

Did a tee Kay test ( i think that's what it's called ) where they put a chemical in the coolant and it reacts with combustion gasses and triggers a reading on something else..... Came back positive!! HG gone!!

Now fully rebuilding my motor....!! $8k here I come!!

Hope your story is NOT like mine.!!

Hope your story is NOT like mine.!!

Thanks Dan, the signs are rapidly pointing to yes. I should just get a 'magic' 8-ball and let it decide my fortune.

My re-build McHeadgasket fix will obviously be less than yours but it's still never a good cheap option. Time to start selling Crystal Meth to earn some dough I think.

You better not be serious Jakey....I've seen first hand what happens when people get into that stuff.

Do. Not. Joke. About. Selling. It.

Dont consider it as an option ever.

[jakey]

Do not joke

Sorry J, just made a Breaking Bad reference - obviously my intentions are not as such.

How are you going with yours at the moment.??
