Ok thank for all the help I now no it my matrix has gone . Don't really want to take the dash out . I have seen on e bay u can get this filler stuff that u put in the rad ,for £9.99 ish .they say it will find the hole and fill it .will this stop the leak . & stop the mist coming in the vents . Or am I just wish full thinking . Any help . Will this work or not

 

Novastop nothing else, hard to find and about £15 a bottle but worth every penny it does exactly what it says on the tin.

 

1509joe . Will this work and it's call novastop . Will have a look for it . When I 1st worm the car up & put the heating on mist comes out of the vents and u can not see out of the front screen . But after a few mins it go's . But all way the next day it's back again . I no it's the matrex that's gone and even I small hole can make this happen . But as u no it means taking the dash out 1/2 day job .

 

Hi this heater thing is not right today the mist only come in the vents for a few sec then it was gone . And the heater worked fine . Any idea on this.
& do u think this rad fix stuff will work . And how do u do it . Run the car for say 10 mins then put the heaters on full and making sure it's on the front screen . Then put the fans on full . Plus do I just put it in to the red . So undo the metal cap then pour it in. P.s the over flow by the battery shod that have water in I.e top that up as well or is it not ment to have water in till things go wrong.
Sound like I don't no much about this and u will be right . This is my 1st Subaru

 

Empty some water out of the header tank on the manifold start the engine with cap off. Warm engine up to operating temperature. Pour in half the bottle top up replace cap. Heater on and run at fast idle for ten minutes. DO NOT PUT ANY IN EXPANSION TANK NEXT TO THE BATTERY. Job done. Yes the bottle next to the battery should have coolant in it fill to max mark.

 

Thank u for all your help . It worth a try £300 plus parts . Or 1/2 days work doing it my self . Thank u

 

Radiator is aluminium, would assume the heater matrix is also. The heads and the block are aluminium.

What do you thinks going to the water galleries?

 

Are you sure you matrix has gone?
I certainly wouldn't be putting any of that shoite in my coolant system, asking for more trouble!
