Quite simply, I was driving along today, and noticed steam coming out of the bonnet. I pulled over at a servo, put a couple of litres of water in the overflow bottle (I thought it'd be better than nothing, and I wasn't game to open the radiator cap). I managed to get about another kilometre before it stopped, with more steam coming from the bonnet (mainly around engine), and wouldn't start again (turn key, nothing)
I identified the culprit (heater hose), and replaced it, and added more water, but now it's not driving all that well. It won't start without touching the accelerator (just won't kick over properly, and it's R31 Pintara GXE auto), and it's a little bit rough.
Also, it sometimes randomly loses power for a few seconds at a time (which it was doing a bit beforehand, as well, i put the foot down a bit harder, and it stops in a few seconds), although apparently the injectors are a bit blocked, so that could be the cause of that. On top of that, after a short trip tonight (7km, mostly at 100km/h), I got back home and could hear excessive bubbling from around the overflow bottle.
I'm just wondering if I've maybe blown something (like a head/head gasket)? I'm thinking about flushing out the cooling system and putting new coolant in tomorrow, but I'm just wondering if anyone has any other ideas?
Thanks a lot in advance,
