Start the engine from cold with the radiator cap off. Watch the coolant in your radiator until it either starts swirling or bubbling.

swirling = good
bubbling = bad

if the head is bad you may also see oil in your coolant (floats on top of the coolant) and if it's really bad then the coolant will literally blow out of the radiator. But I don't think that's going on for you.

Are you sure all the hoses went on right when you flushed the rad and re-installed everything? You could simple have bypassed/blocked something accidently.

specifically,

big bubbles arent bad.

heaps of little, frothy bubbles = really, really, really bad.

na all the hoses got put on properly.

SL666 - Yes it is actually over heating, and yeh cheers it was tested on 120psi hehe oops it overheats after bout 15 to 20 mins of driving.

I have bleed the system as thats the only way i top the coolent up.... I put bout half a litre in when cars turned off the i fill it up when i have it turned on (after bout 30 seconds after turning it on).

Lance - HAHAHA what do you mean by the NOSE knows *sniff sniff* ????? Also considering that the car has been spiking resently i have takin the BC off and i have put the TVIS back on... But its still spiking!!! hehehe ( F&$K NOES )( Theres no splits or holes in the tubing!! )

Gazz - Yes, the thermostat was put back in the correct way.

mtp 69 i - Also the best way i have found if the heads crack is that the oil on the dip stick is milky. But not to sure bout the bubble factor....
Never heard of it that way. haha

SL666 - What do you mean by "Heater Hoses"??? Wheres the heater located? And wot does it look like???

Neways let me no more, cos id love for the car to run perfectly so i can come on the 25th cruise!!!!

so far looking bad!!!

P.S Would anyone be able to come out and have a look at it??? Give me a call on 0405 282 223. And posably fix it or something!!! hahaha....

OK OK OK

If it is the head would a 3SGE head work with the 3SGTE??? Or would i have to use the 3SGTE head off a wreck???
Whats a good company that would recon a head and for how much do you think theyll do it for???

Heater hoses are the hoses that run the water through the firewall into the car to run the heater inside..

A cracked head, or a blown headgasjet might be caused by a car overheating, but i don't think they usually cause it.. not without filling the radiator with air etc..

Does it push water into the overflow bottle? and pull it back out?

when its overheating, is the radiator core *HOT* everywhere? even the bottom tank?

first place to look is the cheapest places... thermostat

thermo fan cut in and out as normal?

I'd cut the bottom of a coke bottle (pref a 2l) stick it upside down in the radiator filler, 2/3 fill it with water, run the car till it gets fully up to temp, make sure the heater is turned to hot, but the fan is off.

Any crud in the system should float out, watch the temp gauge, make sure it doesn't overheat or anything.. check the radiator core and make sure its getting hot water flowing through it..

i'd probably chuck a thermostat at it before that though.. just because they are relatively cheap and seem to f*ck out easilly..

Fixed, thanx for pointing that out.

Milky oil indicates communication between the water jacket and oil feed. There can be a failure between the combustion chamber and cooling system without getting milky oil.

I have suggested previously to others about using a cold screwdrier into the sparkplug hole of a warm engine just after it has been run. If condensation forms on the screw driver then you have a problem.

Try taking the car for a drive with the thermostat removed (or the old one cut up to provide partial restiction) and the thermofans constantly running. With any luck the engine won't get to operating temp, and although it is definitely not a long term solution you have verified the coolant is being circulated and can be cooled sufficiently.

If succeessful then put the thermostat back with the fans on full time.

you're absoslutely correct about the milky oil not always a symptom of bad head gasket.

Also, I'd never heard of that screwdriver trick, that's pretty cool!
