What's Happened To My Cooling System?

So I just went from a subway run (literally 5 mins) and when I was parking up the driveway I smelt coolant... I immediately popped the hood and saw it spraying everywhere so I turned off my car...

After letting it cool down I took off the radiator cap and there's brown gunk shit all over it..

I topped up the coolant which seemed empty but it only took about 2L till full?

Can anyone help me? I don't know what to do and I don't wanna turn my car back on like this :P

could b a blocked radiator

i would try to flush it out and clean it.

AS well as flushing out the engine to make sure u get it out.

if that fails

get a new radiator. Give the engine another flush to make sure its all out.

add a new radiator cap as well.

and where was it spraying from? The radatior cap? or the radiator it self?

Or even the water pump?

Yeah I think you're right I reckon its a blocked radiator.. I don't know how to flush it out myself so I guess I'll have to get it towed to xspeed or somewhere... I hope its not the water pump, I'm on my second water pump already within 5k km... but thats another story..

flushing the radiator is easy

You dont have to pull it out to do it but i would recommend it.

If you can pull it out. Make sure you undo the drain plug underneath first... from memory its on the passenger side bottom of the radatior.

After its outs just shove a hose down the radiator and clean it all out.

THe engine wise you can just put the garden house up the radiator piping to clean it out.

also get a new radiator cap. if the cap doesnt seal right, pressure doesnt build and a fluids boiling point varies directly to the pressure, so low pressure == low boiling point, high pressure == hight boiling point.

Not sure what the boiling point is of coolant, or if this is even the cause, but an old car of mine had overheating and coolant spraying issues and i replaced everything (hoses thermostat etc etc) but the cap last...

damn cap fixed it.

and they're cheap so why not.

turned out it was a busted radiator hose... i took all the radiator off before noticing it ;) oh well, i got a replacement from nissan for $28... also changed the thermostat and radiator cap too while it was all apart :blink:

i think im gonna take it to natrad though since im concerned about that gunk stuff.. its in all the walls of the pipes and would rather get it cleaned out properly

      Hows your intake piping? Are you still running stock? Having in the stock AFM position would mean, if the BOV was shut/venting out, it'd create the almost stalling kind of effect right // "the rich pulse behaviour" due to MAF thinking air is flowing ? But this would be better than having the bov in the stock position + MAF on/just before cross over piping right?

      Essentially, yes. Although I wouldn't put the AFM on the crossover pipe. I'd want to put it into what amounts to the correct size tube, which is more easily done in the intercooler pipework. I bought a mount tube for card stile AFM that replaces the stock AFM - although being a cheap AliExpress knockoff, it had not flange and I had to make and weld my own. But it is the same length and diameter as the stock RB AFM, goes on my airbox, etc etc. I don't have a sick enough rig to warrant anything different, and the swap will take 5 minutes (when I finally get around to it and the injectors & the dyno tune).

      So to summarise, the best thing to do is to move recirc to between turbo and IC, and maf on the crossover pipe. Meaning I'd need a recirc flange, drill a hole in the piping on turbo outlet area. And drill hole on crossover to fit/weld maf sensor? Either that or put the MAF on the turbo inlet right?  Is an aftermarket recirc/blowoff valve recommended? Do currently have family in Japan so could probably bring something back with maybe a cheeky lil SuperAutobacs run?

      Lets play a game - What is causing my oil consumption?

      By tsuokun · Posted

      Yep, so far most have said that it looks like corrosion on the wall from piston not moving. Which then has probably damaged the oil rings and caused those vertical marks. The longest the engine was still after the rebuild, was the winter of 2018 - 2019, plus the boat trip to Japan. When I shipped the car, it had normal gas in the tank but before that winter pause, it had E85 in tank.  In any case, even if either one of those was the cause, it happened close to 6 years ago and the car has been driven something like 30 000kms after the fact. Again, apart from the plugs and the dip stick, there is nothing in the way the car runs that would indicate what has been going on in the engine. I am going to consult a shop and ask their opinion, what would be the best approach. I do have some access to a garage I could use to diagnose further myself, but time is very restrictive. Might end up buying another engine that could be used while this one is being remedied. Without pulling the head, it will be impossible to find out if it needs another bore, but here's to hoping a hone would suffice.  Goddamnit, I would really have preferred this not happening.

      Got this r31 silhouette flood car to rebuild.

      Boot is going to be replaced eventually. I just wire brushed what I could and rust converted. Then painted in rust kill primer. the spoiler also got repainted and plugs replaced on the ends. The under side of the bonnet is going to be black also, currently white. But red on the top side, same colour code as the silo to begin.
