Coolant System Corrosion

Recommended Posts

In reference to my previous thread: http://www.mkivsupra.net/vbb/showpost.php?p=2294617&postcount=17

 

There was no cover over the coolant pipework and as a result (i would imagine) there is rust inside as well as a number of bugs and who knows what else.

 

How would I get this out? Is there some way of doing a flush of the coolant system in it's current condition? I think this would need doing before the engine came out as it can be run as it is now.

 

Any advice?

 

Thanks as always :)

I wouldn't have the first clue what to do with something like that, and being on the IoM there's not much choice available :(, and I wouldn't trust many with this type of thing over here anyway.

 

If I feed water through the top rad hose will the thermostat not stop the water from getting fully round the system? Or can this be removed?

no u just gotta get it upto temperture for it to open, thats if it works of course.

I really wouldnt worry about it now, whatever is in there its to late now, just put it in then give it a good few flushes as many times as you think.

You dont wanna risk causing damaged to head gaskets etc

Which pipework are you talking about?

 

There is naturally some amount of corrosion in a coolant passageway anyway.

 

I would be a lot more concerned about starting it up and revving it up with nothing properly connected....

 

The top rad hose is the one I was thinking of. I think the best thing to do would be to get a rad on there, do some flushes and hope for the best!

 

I just hope some little spider family hasn't decided to make it's home in there and block something up! Is this even possible? Engine internals are pretty much new to me so I rely on help from you guys for this info! :)
