Hey Guys,
Dont post much hear, but spend heaps of time looking at the forum...

Anyway...i have an issue...i pulled up in my VS commodore ute this afternoon and could here a hissing sound coming from under the bonnet. Upon further inspection it seemed to be leaking from a "purge tank" that is bolted to the radiator area at the front on the drivers side. There are 3 hoses coming from this tank...

Ok...so i have looked through some books etc i have hear and done a search online but still have no clue what this tank does nor how to fix the problem. I am assuming that the "purge tank" will need to be replaced, but what is it for and is it something i can do??

Any help will be really appreciated...

Cheers

Here are some photos of the location of the tank....

Are you 100% sure its coming from there? Iv never heard one hiss before? And its under vacuum.

Looking at the bottom picture, I would be tempted to check the top radiator hose, they will often split at the clamp and you won't see it. That hose looks pretty gone to me as can be seen by the rounding at the back of the clamp.

Yep agreed with above, and the suspected "water marks" on the Carbon Canister is a bit of a dead give away there is a leak coming from the hose.

Thanks guys...i will check it out in the morning. I was sure the hissing was coming from the canister...but i will check out the hose.

I reckon it ain't the hose...it's the side tank that's split where the top hose clamps on....this is the usual fail point. If not replaced soon, it will blow completely. Ebay has radiators for about $100 delivered.

SO would the carbon cannister not be holding pressure and the hose would be?? I just had a quick look at the hose and it looks fine.

Hmm...so the radiator itself huh?? I will have to check it out.

Ok...so after doing a search on buggered radiators i found this...Leaking Radiator

Sounds pretty close to what i have.

Will a new radiator fix the entire problem?? I see they go for about $80 off ebay....is that the best bet for a new one??

Thanks again...

Well what a saga this has turned out to be. I took the radiator out and in the process of taking the transmission cooler hoses off discovered that who ever put them on cross thread one when they were doing it up. Then when i went to undo the other end of the the hose from the trans cooler, it broke to...

I have also discovered a leak coming from my water pump....

So from what looked like an easy job replacing the radiator is gonna end up costing me about bloody $350 and a shit load more rooting around....

END RANT...

Do the heater tap, rad cap and thermostat while your in there.

If you order a radiatior with push on trans fittings, you can then just double clamp trans hose on to it.
