Header tank bubbling ?

[WizardKing]

After a good run, on my return home from having my transfer box and trans. cooler fitted (cheers Kev!), I found water bubbling in my header tank.

Might this be down to the radiator-cap issue ?

[swinks]

Yes..., but also:
- air in the system (not refilled properly)
- loosen/leaking hose (you're loosing coolant, air gets in)
- leak in new radiator
- worst nightmare: headgasket failure

Sounds farmiliar bud. Just one of the issues i had before i got rid of it.
Hope you get it sorted...... I had a new rad fitted shortly b4 I sold it. Have you changed it again since?

[WizardKing]

Thanks. No, same rad. (I thought it was new, b.t.w.)

I'll be trying another cap on it tomorrow and shall report back after.

mine did that when the radiator cap was bung

Update :

I've now done four 80 mile trips (motorways) and haven't topped-up the header tank, at all !! [Previous to fitting a new rad-cap, I'd have done it 4 times.]

Hopefully, it's sorted. /Banana




Cheers for the info, Subaru ETA, gives me a bit more confidence.
