I'm stranded - 4.8 blew a radiator apart and then hole in replacement

[SpecialDave]

My pressure is way up and split the top open on my radiator so I managed to get a replacement from wreckers and it either had or developed a small hole - what would cause my system to have increased pressure - I'm sitting in a car park on a night that may have snow - I have heaps of tools etc.

Heater core? Any suggestions as I'm lowcash and need to get her going at least to limp home

[Sir Roofy]

thermostat jammed shut hope someone is close by to help you out

[SpecialDave]

How does one Unjam thermostat?

if you think that's the problem just take it out and get yourself home
keeping an eye on temps you should be ok

Pressure is due to cap not working or leak from a cylinder pressurising the system.

Take the cap off and check for air bubbling out of the radiator. If not too bad you could possible drive it.

where are you?
I'd try just removing the thermostat just to get home. Hopefully this might help.

Therms removed now in motion - fingers crossed

Good luck bud, hope you don't have far to go. I assume your not in the RACV?

[SpecialDave]

Nope and couldn't afford to keep roadside (going through very ordinary divorce) so it's gotten very hot and I'm pulled over letting her cool - only another 20kms to go

Bugger mate, sorry dude, that would be shit. Have you got plenty of water? Where are you? If I was close I'd come get you mate but I'm in Geelong mate.
