Ok get ready for a real headache. To change that head gasket you will have to have a lift, some special tools and about 20 hours( for a trained mechanic). It involves removing the rack and pinion steering, oil pan, all of the parts off of the front of the engine, and timing cover. Then the fun begins. That engine has no timing marks on the outside of the engine. You will have to pull the exaust, and intake manifolds, valve cover and coils. Roll the motor by hand till you get all the timing marks lined up han then you can remove the head. If you are not a trained mechanic, you are really getting a tough one to start on. You will need a manuel on all the specs, Good Luck

I think there's a good chance you are right. A trip to your local garage for a pressure test on the rad or a compression test on the engine will let you know for sure. You are probably looking at replacing head gaskets. Hope this helps.

Running hot, changed thermostat and flushed coolant, also changed top hose. Any ideas why it would still run hot?

1. blocked radiator core
2. blown head gasket
3. cracked head
4. water pump
These would be the major problems causing the overheating.
Timing could be another but unless the timing has been changed recently it is most probably one of the causes
