car dumping coolent

[Major Monaro]

Ok so my ro 6.0 vxr keeps dumping water after I've switched the engine of, seems like it's boiling over and coming out under the overflow tank. Haven't heard my fans either, any ideas people. Thanks

[Major Monaro]

Also when I checked the overflow from cold it was empty and when I took off the main rad cap the level was about 5 inches from the top so topped up the overflow and now it's dumping again, could this be too much water in the system. It has just had its 50 k big service

Maybe time for a new rad m8

[Major Monaro]

It had a new rad 18 months ago mate

[jameshsv]

OH that dont sound good then maybe air in system or hopefully a hose needs replacing

[Major Monaro]

Would a worn rad cap do this do u think

Why did you not top up the main tank ?

[Major Monaro]

Tried that and same result mate. The temp quage in car seems normal it's never gone over half way. Need to speak to monkfish as not sure if the 50k service has anything to do with coolant replacement/level

I was loosing coolant on mine, changed cap and all was fine

[Major Monaro]

Sounds like hopefully it's the cap then shall get the fish to send me one out. Will report back

FWIW I've never been advised to top up the overflow only ever the main rad and add fluid SLOWLY otherwise you'll only make matters worse.

i had this problem on a prelude i used to own after a radiator change.....the stealers didnt get rid of all the air in the system so it used to blow most of the coolant out everytime i topped it up.

TIs it still happening
Thought it was solved , oh well mines not broke been out all day upsetting most performance
Cars today had lots of fun
Perhaps it's time to think about moving on to something more reliable
