quick question GT legacy

[swiftbrad]

heyas,

Traffic was chaos after work, ages spent idling at lights before moving a few metres. Noticed temp guage was reading slightly over half way when it always reads slightly under half way. It didnt get any hotter and when we were finally moving again it dropped back to normal.

Waited a few hours for it to cool down and it took 1.5L to fill it back up, cant really be a good sign.

Question being, with rad cap off and applying gentle throttle, after taking foot off gas the water gentle overflows the rad but is quite frothy on top, lol. Is that normal?

Dipstick oil doesnt look milky but the water has clearly gone somewhere and havnt noticed any leaks on driveway etc.

cheers

TBH sounds normal to me. Make sure you have the over flow topped up too. Check in a few weeks, and if the over flow hasn't changed, nothing to worry about.

sounds like your thermastat is given up the ghost my freind.it might not be opening all the way causing the water to back up on itself.get it check first. ;)before you start panicing.

Sounds familiar, bar the temp gauge fiddling around. My 20G-powered Legacy loves to froth with a bit of throttle too, but refuses to budge on the temp gauge. She consumes water too.

Is that burning money I smell? :-X

Has it done it since, swiftbrad?

I had similar problems with my BF5 GT when I bought it last June. I was concerned that we were dealing with potential head gasket failure but it was just the radiator. It was so clogged up that even the flush didn't get all the crud out of the cooling system. I fitted a s/h radiator which was known to be good, and the problem was solved.

As a precaution we also fitted a new water pump and thermostat but the radiator was the prime culprit. I've had no more concerns with engine temps since then, and that was over 25,000km ago. The wagon gets used for towing, long trips and peak hour traffic periodically so if there was a problem it would have shown up by now.

Think I was a lil panicky on the frothing thing, hasnt over heated since but seems to lose about 250ml of water in 2 days, so just keeping eye on water level until I get time to get it sorted. Its such a small loss that I havnt noticed anything on driveway etc I guess. Not sure but I'd say if it was head gasket issues it would have reared its ugly head by now. I do 100kms a day so have done heaps since first post.

Hmm yeah - know the panic. Been there done that with blown thermostat, blown waterpump and resulting blown headgasket...trust me ya know about it!

Possibly time to look at a few frothing radiators at this point. Or give 'em a rabies shot.
