Why! I've never needed to do that, and I've done it many times in the 23 years of owning my Patrol, to complete circulation the flow out from under the top tank is required.also put a vice grip near cap overflow on small hose from top tank to coolant resy
I closed the main tank and filled from the top tank with a sealed funnel.Why! I've never needed to do that, and I've done it many times in the 23 years of owning my Patrol, to complete circulation the flow out from under the top tank is required.
Yes it is, I had no white smoke when my gasket failed to the small water gallery between cylinder 3 and 4. I had done pressure tests, I had done the sniff test and all passed (we do know the sniff test on diesels is not always effective), but I still had bubbling in the lower tank so time to remove head and look.I closed the main tank and filled from the top tank with a sealed funnel.
I am still getting severe bubbling so sadly think I have a headgasket issue.
@geeyoutoo is it possible for this to happen and not have white smoke out the exhaust?
Yeah I'm pretty certain it's a small leak in the gasket. If it was a piston I'm sure I would have loss of power.Yes it is, I had no white smoke when my gasket failed to the small water gallery between cylinder 3 and 4.

if u are in perth wa i have a test kit u could use to check exhaust leak.. i picked it up just before christmas to check mine.Yeah I'm pretty certain it's a small leak in the gasket. If it was a piston I'm sure I would have loss of power.
Check my post #27, sniff testing a diesel cooling system is not reliable, I knew it already but had a local guy do it anyway, it passed and I still had bubbling.if u are in perth wa i have a test kit u could use to check exhaust leak.. i picked it up just before christmas to check mine.![]()
That’s a why i thought id offer up mine as not worth spending money if u don’t have to. when i did my test it was an instant result. either way i have one if anyone wants to borrow.

Interesting, not my experience after many coolant changes. Just to clarify, I also have the pressure cap off the upper tank.Just to add my experience to this. I found it difficult to remove air lock without pressuring the system.
The funnel/ plastic bottle method should work with heater on but I found it didn’t seem to fully circulate without the cap on the header tank.
Keep us informed mate.Cheers guys
It is now bubbling the coolant res instantly so definitely a head gasket.
Just really hoping that's all's it is
If you see it come up for sale you will know it was more 😂. Budget can't afford much more than a head gasketKeep us informed mate.
Just go’s to show every car a little different. I have had mine for 13 yrs and done about 8 flushes over that time use to fill from radiator then about 8 yrs ago started filling from top tank and seemed to work better so just kept doing it. With mine i need to rev a bit for it to heat up enough for thermostat to open and normally go for a quick drive afterwards then check coolant once back and cooled down a bit. So far this works for me.Just to add my experience to this. I found it difficult to remove air lock without pressuring the system.

I put mine on fast heat up idle, 1200rpm.Just go’s to show every car a little different.

best of luck with the head gasket flow.
