Check fluid level.
Check hoses for cracks/splits.
Have radiator specialist pressure test cooling system.
Check engine oil for level and or discolouration.
Tech 2 test for any error codes - if any, respond/repair accordingly.

Yep as BenBoy says also if water gets in the oil it foams up
I'd change the thermostat it might be sticking shut

check the coolant cap... next to the throttle body

Check if your thermos coming on??

Also try bleeding air from the radiator bleed screw. Search for the procedure on here somewhere.

if you wanna bleed your radiator, take the big plastic shroud off the front of the engine bay..on the left at the top of the radiator, on the side facing towards the engine, there will be a little screw..white if i remember correctly, just have the engine running, undo that screw bit by bit untill a bit of coolant pisses out...wait a little while, do it again...feel the top and bottom radiator hoses, when they're gettting quite hot (meaning ur thermostat is fully opened), do the same again, and that should be it

I would say it is either your thermostat or coolant lid. I would try replacing these and then see what happens. Even if it isnt the cause they are the cheapest options and will prob need replacing anyways.

My Car was overheating recently 2005 SS, took it to holden and they told me it was my radiator, so I replaced it.
Car overheated 2 days later. took it back to holden and they said, nah its not your radiator its your thermostat.
same day the car over heated. took it to a different emchanic at AUTOMASTERS and they told me it was quite evident it was my water pump.
They quoted me shitloads for one to be installed ($850) and so did holden so I found one online for $177. brand new aftermarket. and got Ultratrutune to installit and bleed radiator again.
THIS FIXED MY PROBLEM!!!!!
