Overheating

[Chookz103]

Hi crew my ve v8 keeps blowing of the top radiator hose and losing water it seams like the system is pressurised,I have drained and flushed the cooling system and replaced both top and bottom hose and put a new radiator cap it will only go like 10 minutes of driving I found the top plastic part on the radiator were the top hose goes onto is broken of and there is nothing to stop the hose slipping off
Your thoughts

Not uncommon.

New radiator will fix it.

Radiator is broken, need to buy a new one.

Or a suss head gasket pressurising the cooling system?

Test the cap. Is it opening?

Compression test first. Radiator second.

How many times has the radiator neck broken off?
If you keep trying to connect the hose to that broken neck that is obviously the reason why the hose keeps popping off.
Radiators typically fail at about 200,000km. How many ks has yours done?

Edit: Bloody hell. Get a new radiator. I didn’t read the post as well as I should have.

Phew, I thought a compression test was a bit over the top for a broken old radiator
