Answer 1

A head gasket leak seems most likely: remove rad cap when cold, let engine warm up, check for bubbling or froth in coolant. Another tipoff is if you have to add coolant regularly (is expansion tank often dry?) Worst case is if the exhaust shows 'white', that's steam from water in combustion chamber. First, pull all the spark plugs, keep them in order, and check for one or two very clean plugs (again steam) to localize damage. Also, does engine run rough after cold start, then smooth out? That's also sign of one or two 'wet' cylinders. Gasket, again.
A cracked head is less likely, but produces same symptoms. Water loss is true for both cases; check for drips and rusty-looking stains on or around engine- I would guess you have already checked for loose hose clamps or soft-feeling upper coolant hose to radiator.
If the engine oil is frothy or other than black/clear, (does oil level tend to rise?) then there is leakage in heads or block. Total worst-case.

Answer 2

its prolly your fan not kickin in
start it up in your driveway and when its starts to overheat pop your hood and look to see if its runnin

as long as u aint leakin water or havin a lot of smoke most likely your heads are ok but be careful cas if they keep overheating they will

Answer 3

Faulty electric cooling fan.
